Hi everyone,

We're a bit late on this. Please let Dick and I know ASAP if you'd like 
a slot on the London meeting agenda.

Thanks,

--f403045e8b7cf9732c0566722ce0
Content-Type: text/plain; charset="UTF-8"

I have a few other suggestions:

1. In section 1.2 we could drop the definition of Identity Provider and
Relying Party. I don't think these are necessary in this spec.

2. In section 2.1, the description of the PUSH delivery mode states that
the response must contain "Content-Type: application/json". I think that is
the case only for error responses, I think on success no Content-Type is
needed at all.

3. In section 2.2, it is stated that "the Event Receiver SHALL indicate an
HTTP Status 400 error with an error code as described in Section 2.4". I
think that some error codes should be matched by other 4xx codes (for
example 401 and 403). I think it would be useful to list all the possible
error codes and corresponding HTTP Status codes in this section and not
refer to 2.4,

4. In section 2.3.1, the description of maxEvents, at the very end. A
conflict between zero request events and returnImmediately is described and
the later should be ignored. I think this should not be a silent ignore but
an error condition,

The current spec is at:
https://tools.ietf.org/html/draft-ietf-secevent-delivery-01

I am happy to send pull requests for all these changes. Let me know.

Thanks,
Marius

Marius,

Thanks.

Item 1 and 2 look reasonable.

for Item 3, 4, I think the group should review. See below.

Given the submission deadline is Monday, it would be good to wait group =
confirmation of your proposals.

conflict between zero request events and returnImmediately is described =
and the later should be ignored. I think this should not be a silent =

<PH>The value of 0 is used to allow a poller to acknowledge previously =
received SETs without having to process or wait for new events. Thus =
returnImmediately is assumed. Thus the value of returnImmediately is =
ignored.

Some participants indicated a desire to keep acknowledgement threads =

Annabelle,

Apologies, but =E2=80=9Csignificance of this case=E2=80=9D does not seem =
to add actionable information or aid in understanding. Also "if any=E2=80=9D=
 seems unclear.

Can you propose something else (with before and after text)?

Thanks,

I think jwtAud and jwtIss should be 403 and not 400.

<PH>
jwtAud and jwtIss are issues with the payload.  403 indicates the wrong =
authorization credential was used. E.g. a bad authorization header.

It is important to distinguish between an http authorization header and =
a malformed SET.
>=20

<PH>
I think dup is no longer needed as we changed language to allow =
recovery.

setType - We should maybe update the terminology to setEventUri =
indicating the receiver is refusing a specific event type.

406 is the closest, yet that code is about media types not being =
acceptable.  406 can occur if someone requests application/xml for =
example.

<PH>
See section 2.3.3, in particular acknowledge only (2.3.3.2).  =
=E2=80=9CmaxEvents=E2=80=9D:0 is what makes a request ack only. It can =
be expressed in a more obvious way, but I believe the discussion was =
this was simpler overall.

returnImmediately:true in the case of 2.3.3.2 is redundant. It isn=E2=80=99=
t an error because control always returns immediately.  =
returnImmediately:false would however would be an error because there is =
nothing to return in section 2.3.3.2.

Looking at the text, it looks like we need to clarify that either an =
error is returned or just an acceptance when maxEvents is 0.

                                I will be document shepherd for the SET
                                spec. As such, I just reread it once
                                again, and I think it is in very good
                                shape. Here are my (mostly editorial)
                                comments.<br>
                                <br>
                                - Abstract: please add the following to
                                clarify, e.g. after the first sentence:
                                SETs serve to exchange information about
                                identity-related events.<br>
                                - A security subject MAY be permanent -
                                this is descriptive text, please change
                                "MAY" to "may".<br>
                                - "SETs have no capability for error
                                signaling to ensure the validation of a
                                received SET" - SETs are a format, so it
                                is a higher level protocol that may or
                                may not signal errors. I suggest to
                                remove this sentence.<br>
                                - "has occurred about a Subject." Should
                                this be "has occurred to a Subject”?<o:p></o:p></span></p>

                                full names of the claims ("Issuer", "JWT

                                - IMO the distinction between JWTs and
                                SETs with regard to the need to use
                                "exp" is not convincing. I suggest we
                                refer to Sec. 4.5 for a better rationale
                                why we make this claim NOT RECOMMENDED
                                rather than OPTIONAL as in RFC 7519.<br>
                                - txn: this paragraph should speak about
                                SETs rather than JWTs.<o:p></o:p></span></p>

Marius,

given the timeline, please make whatever changes you see fit, and 
present them in London with the understanding that the group might ask 
you to backtrack.

Thanks,
	Yaron

I am not suggesting 401, but 403. The request is perfectly valid, but the
iss or aud presented are not allowed to send events to this receiver.

Maybe you are right, we can probably drop "dup". I don't see any value in
it for a Transmitter.

setEventIdentifier? To go with the latest terminology in the SET spec.

Even 403 might be a could status in this case. 406 seems to be related to
the "Accept" header, and that's not the case here. 415?

How about invalid "typ" claim in the SET header?  415?

Also, how about 429 for too many requests?

Agreed with all of the above. I was suggesting to return an error for
maxEvents:0 and returnImmediately:false.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Security Events WG of the IETF.

        Title           : SET Token Delivery Using HTTP
        Authors         : Phil Hunt
                          Marius Scurtescu

	Pages           : 26
	Date            : 2018-03-04

Abstract:
   This specification defines how a series of security event tokens
   (SETs) may be delivered to a previously registered receiver using
   HTTP POST over TLS initiated as a push to the receiver, or as a poll
   by the receiver.  The specification also defines how delivery can be
   assured subject to the SET Token Receiver's need for assurance.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Security Events WG of the IETF.

        Title           : Security Event Token (SET)
        Authors         : Phil Hunt
                          Michael B. Jones

	Date            : 2018-03-04

Abstract:
   This specification defines the Security Event Token (SET) data
   structure.  A SET describes a statement of fact from the perspective
   of an issuer about the state of a security subject, which is intended
   to be shared with one or more recipients.  This statement of fact
   represents an event that occurred to the security subject.  In some
   use cases, the security subject may be a digitial identity, but SETs
   are also applicable to non-identity use cases.  A SET is a JSON Web
   Token (JWT), which can be optionally signed and/or encrypted.  SETs
   can be distributed via protocols such as HTTP.

&nbsp;&nbsp;This specification defines the Security Event Token (SET) =
data<br class=3D""> &nbsp;&nbsp;structure. &nbsp;A SET describes a =
statement of fact from the perspective<br class=3D""> &nbsp;&nbsp;of an =
issuer about the state of a security subject, which is intended<br =
class=3D""> &nbsp;&nbsp;to be shared with one or more recipients. =
&nbsp;This statement of fact<br class=3D""> &nbsp;&nbsp;represents an =
event that occurred to the security subject. &nbsp;In some<br class=3D""> =
&nbsp;&nbsp;use cases, the security subject may be a digitial identity, =
but SETs<br class=3D""> &nbsp;&nbsp;are also applicable to non-identity =
use cases. &nbsp;A SET is a JSON Web<br class=3D""> &nbsp;&nbsp;Token =

Generally looks fine. I think the main thing that need to be resolved is
what is MTI. From Singapore, there was a suggestion that it be up to the
transmitter to decide whether to push, pull or both. This is not ideal as
some Transmitters may support push while other Receivers may only be able
to accept pull. It seems there is a bit of an enterprise/consumer split
here where enterprise receivers are more likely to need pull to deal with
firewalls while consumer transmitters are likely to want to support only
push to protect themselves from polling load of high number of clients.

I don't see much way around this situation for the spec. It seems
unreasonable to force large consumer transmitters to take high frequency
polling from a large number of clients and it's impossible for some
enterprise receivers to get outside their firewall restrictions. I think
the only answer is with the formation of intermediary services. These can
serve as a queuing mechanism taking the signals from consumer Transmitters
and enabling polling of them by enterprise Receivers. Similarly, these
service providers could also poll for data form enterprise Transmitters
that only support polling and then post those events to consumer Receivers.

I think we should accept that forcing both push and pull on the whole
ecosystem is unreasonable and that if there is a high need for interop
between consumer and enterprise, service providers will step in to provide
the glue.

The solution we discussed was to split the delivery draft into two: one
separate draft for push and another separate draft for poll. This way each
provider can chose to implement the delivery methods they want. This also
sets the precedent to create other delivery methods easily.

I will start a separate thread on this regard. Hopefully in London the
working group can have a discussion and decision around this.

<div>Generally looks fine. I think the main thing that need to be resolved =
is what is MTI. From Singapore, there was a suggestion that it be up to the=
 transmitter to decide whether to push, pull or both. This is not ideal as =
some Transmitters may support push while other Receivers may only be able t=
o accept pull. It seems there is a bit of an enterprise/consumer split here=
 where enterprise receivers are more likely to need pull to deal with firew=
alls while consumer transmitters are likely to want to support only push to=
 protect themselves from polling load of high number of clients.=C2=A0</div=
><div><br></div><div>I don&#39;t see much way around this situation for the=
 spec. It seems unreasonable to force large consumer transmitters to take h=
igh frequency polling from a large number of clients and it&#39;s impossibl=
e for some enterprise receivers to get outside their firewall restrictions.=
 I think the only answer is with the formation of intermediary services. Th=
ese can serve as a queuing mechanism taking the signals from consumer Trans=
mitters and enabling polling of them by enterprise Receivers. Similarly, th=
ese service providers could also poll for data form enterprise Transmitters=
 that only support polling and then post those events to consumer Receivers=
.=C2=A0</div><div><br></div><div>I think we should accept that forcing both=
 push and pull on the whole ecosystem is unreasonable and that if there is =
a high need for interop between consumer and enterprise, service providers =
will step in to provide the glue.=C2=A0</div></div></blockquote><div><br></=
div><div>The solution we discussed was to split the delivery draft into two=
: one separate draft for push and another separate draft for poll. This way=
 each provider can chose to implement the delivery methods they want. This =
also sets the precedent to create other delivery methods easily.</div><div>=
<br></div><div>I will start a separate thread on this regard. Hopefully in =
London the working group can have a discussion and decision around this.</d=

Content-Type: text/plain; charset="UTF-8"

The current delivery draft defines both a push and a poll delivery methods:
https://tools.ietf.org/html/draft-ietf-secevent-delivery-02

Two issues have been raised with the current draft:

1. Many implementors raised the concern that they want to implement either
push or poll, but not both. With both delivery methods in one spec
optionality is tricky, the suggestion was to make them MTI, but not
mandatory to deploy which is very confusing.

2. For the draft to move to Last Call status we need implementors for all
parts of the draft. Currently there are push implementations, but not poll
implementations. By separating them we can allow the more mature method to
move forward while allowing the less mature method to be refined and gain
implementation feedback.

Also, by having separate specs per delivery method we set the stage for
other delivery methods to be added easily.

Can we add this to the agenda to be discussed in London?

The discussion should answer:
A. Do we have consensus for splitting the delivery spec into two?
B. If yes for A, can the two new specs replace the existing spec and stay
as working group drafts (this would be ideal)? As opposed to the two new
specs starting from scratch as I-Ds.

If it helps, I am happy to send to the list two separate specs as TXT/PDF
so we have something concrete to look at. Let me know.

I will not be in London, but will try to attend remotely.

Thanks,
Marius

I agree polling is expensive, however the number of streams is minimal compa=
red to the users being federated. After all this is a backchannel service.=20=


Push is complicated by management and status checking which occur in the opp=
osite direction to the set delivery requiring mutual credential sets etc.=20=


Polling on the other hand could be done with a single set of credentials for=
 delivery pick up and management.=20

Further polling could be made bi directional=E2=80=94>halving the number of c=
onnections to support and manage.=20

I am not saying go one way or another. Just want to hi-light that both have t=
heir pros and cons.=20

Ps. There are a lot of network and firewall restrictions in backchannel data=
 services in general.  This is not exclusive to enterprise firewalls.=20

I suggest exploring more options during the week in London.=20

Due to some scheduling conflicts only a few could make it today. I also =
notice that the proposed time of 6PM for tomorrow is in the middle of =
the plenary.

Instead of the 6PM session, I would like to suggest we get together for =
lunch at the Fiamma restaurant(in the hotel) Wednesday at noon instead =
of 6PM

If that works, please confirm and I will cancel the 6PM session.

Thanks

Subject: [Id-event] rescheduled working meeting

Due to some scheduling conflicts only a few could make it today. I also not=
ice that the proposed time of 6PM for tomorrow is in the middle of the plen=
ary.

Instead of the 6PM session, I would like to suggest we get together for lun=
ch at the Fiamma restaurant(in the hotel) Wednesday at noon instead of 6PM

If that works, please confirm and I will cancel the 6PM session.

Thanks

We held a couple of brief sessions over the last couple days.

We talked about the issue of breaking up the delivery document, multiple =
delivery methods, and optionality.

Some observations:

1. Yaron indicated that the IETF will likely require one method be MTI =
(mandatory to implement).

While PUSH has better scale (because it does not need HTTP Long =
Polling), the POLL method has broader utility due to the presence of =
receivers with firewalls, gateways (IoT devices), or are mobile =
applications that cannot implement endpoints to receive HTTP POSTs.

2.  If POLL is chosen as the MTI method, many will still likely prefer =
PUSH and so that will likely get implemented sooner by some

3.  There was a general feeling that the delivery draft should stay as =
one draft.

Annabelle will present her recommendations at the formal meeting on =
Friday where we can get broader input.

Thanks everyone.

Receivers with this issue can mitigate the problem by implementing an
intermediary routing service which will accept messages from push
transmitters and buffer them until their clients poll for them.

Google has no plans to implement polling due to the fact that we cannot
effectively rate limit the polling interval from potentially hundreds of
thousands of clients. This represents a DDoS risk to us. This is especially
true if our service were to go down for a non-trivial period of time and
our universe of clients would likely all hammer us once we got online again.

Subject: [Id-event] rescheduled working meeting

Due to some scheduling conflicts only a few could make it today. I also not=
ice that the proposed time of 6PM for tomorrow is in the middle of the plen=
ary.

Instead of the 6PM session, I would like to suggest we get together for lun=
ch at the Fiamma restaurant(in the hotel) Wednesday at noon instead of 6PM

If that works, please confirm and I will cancel the 6PM session.

Thanks

Phil

It would be very useful to point to other working groups and specs where
this was the case.

What is the mechanism by which a specific delivery method is made MTI?
Which meta document specifies that?

What happens if a provider is not implementing the MTI delivery method?
What does that exactly mean?

Just trying to understand what the process is.

To me it is very unlikely that IoT or mobile devices will use POLL (or
PUSH). They will need some other delivery methods appropriate for their
architecture. Having the current PUSH or POLL mandatory for these cases
does not make sense to me,

Many will simply not implement POLL if what they need is PUSH, and vice
versa. Again, I don't see how the working group can pick any delivery
method and make it MTI. And MTI in what context?

Can we escalate this issue within IETF to get guidance?

I don't see how that is helping, but if implementors can chose either PUSH
or POLL from the current draft then that's fine. But in that case splitting
should also be acceptable.

Hi Marius,

The decision about whether we need to have an MTI protocol and which one 
it should be is up to the WG consensus, like everything else. But with 
my WG chair hat on, it is my strong conviction that we need to have one 
MTI method to encourage interoperability and reduce fragmentation. This 
is based on my IETF experience, and not on any meta-document as far as I 
can tell. Just think of implementers that are not part of the WG, and 
just read the RFCs two years from now. They need to have a clear message 
which method will allow them the best (though maybe not perfect) 
interoperability. Also, I personally do not have a preference which of 
the methods becomes MTI.

It is common at the IETF to say that "there is no IETF police", in other 
words if you choose to not implement an MTI protocol/feature, nobody is 
going to come after you and punish you. It is between you and your 
market. I fully expect some of the WG participants to only implement the 
non-MTI method.

We can absolutely ask the incoming AD for more guidance in this area.

I think keeping the two methods within the same document will speed up 
and simplify the process, compared to running two docs in parallel. They 
do have enough commonalities.

Thanks,
	Yaron

Section 2.2 for "exp" states:

"this claim is the time after which the JWT MUST NOT be accepted for
processing.  In the context of a SET however, this notion does not
typically apply, since a SET represents something that has already occurred
and is historical in nature. Therefore, its use is NOT RECOMMENDED."

Similarly, section 4.5 makes recommendations against "exp".

At IETF 100 in Singapore we briefly talked about this and the following
problem came up: without "exp" how long should a receiver cache "jti"
values to prevent double submissions (and replay attacks)?

Today the same problem was raised as implementation feedback.

It seems that "exp" should rather be required. Thoughts?

What happens to section 4.5 if "exp" is required?

Also, a required (or recommended) "exp" leads to implementation challenges
when it comes to delivery. A transmitter that is retrying to deliver
unconfirmed SETs, will have to probably re-mint them on each delivery
attempt, as opposed to simply cache a minted SET and keep retrying with
that. Or the transmitter will have to set an expiration period longer than
the retry period, but long expiration periods put bigger loads on receivers
(larger cache).

Any chance this can be discussed on Friday?

Hi Yaron,

I don't think anyone can argue with the desire for strong interop and less
complexity.

Wearing our implementor hats, what delivery method would optimally cover
all use cases? Do we want a delivery method that in theory can cover most
use cases, but it is suboptimal for many of them? How would a mobile or IoT
device use the current PUSH or POLL methods?

We are not talking about alternative delivery methods for the same use
case, but different methods for each separate use case. I totally agree
that as a workinggroup we should support one method per use case, for
example one method for HTTP receivers sitting behind firewalls. I am using
"use case" in a generic way, more like "profile".

Why declare one method as MTI when it is clear that it will not work for
many use cases and that implementors for those use cases will be forced to
ignore the MTI?

Regarding the current delivery draft, why do you think that keeping the two
methods together is beneficial? The overlap between the two is minimal.
Here are the reasons why I think the draft should be split:

1. The two methods have different maturity levels. The PUSH method is
already implemented and more implementation will come online soon. The POLL
method has no implementation yet, as far as I know. By keeping them
together we hold back one and put pressure to rush the other. That's
lose-lose.

2. With two methods in one drafts it is very ambiguous what is MTI. With
two separate drafts each implemetor can chose what works for their use
cases. Interop will work out based on use cases, I don't think we have to
force it.

The clear message for implementors two years from now would be a clear
description for each method as to what use cases it is applicable to. No
confusion at all, if you are behind a firewall then POLL is your only
option. If you are delivering to IoT then whatever method works for that
use case (we don't have one yet).

I asked about a meta-document from a practical point of view. How/where
will the MTI delivery method be defined? Same with IETF police, maybe you
misunderstood. I am not worried about implementors disregarding
recommendations. Since the unit for specifications are RFCs, how can some
RFC be declared as MTI? In what context? Again, from a practical editorial
point of view.

Guidance would be very useful IMO.

Thanks,
Marius

e, be based on a deployment-specified delta from the =E2=80=9Ciat=E2=80=9D (=

Speaking to one draft I worked on where we faced this decision, PKCE
Section 4.2 <https://tools.ietf.org/html/rfc7636#section-4.2> defined two
methods to transform the code challenge, plain text (no transformation),
and SHA256.

"S256" is declared as MTI in the spec, and "plain" is not. In this case we
actually say "Mandatory to Implement", but gating SHA256 with a "MUST" and
the "plain" with a "MAY" would have achieved the same effect.

I advocated for making S256 MTI (when I first reviewed the draft, both were
given equal weighting) so that native app clients would not need to perform
discovery on the server to work out which method they can use (and provide
additional API methods for the developer to specify the transform for
servers that don't support discovery). Since SHA256 is MTI, all native app
clients can rely on it being implemented.  And that's what AppAuth does, it
has no support for "plain", and doesn't bother with doing discovery on the
PKCE method, which greatly simplified the implementation (and it's
completely seamless to users of AppAuth). As we required MTI on the more
secure option of the two, this also resulted in more secure implementations
by default.

YMMV =E2=80=93 but that's what we did in that case :-)

<br>
The decision about whether we need to have an MTI protocol and which one it=
 should be is up to the WG consensus, like everything else. But with my WG =
chair hat on, it is my strong conviction that we need to have one MTI metho=
d to encourage interoperability and reduce fragmentation. This is based on =
my IETF experience, and not on any meta-document as far as I can tell. Just=
 think of implementers that are not part of the WG, and just read the RFCs =
two years from now. They need to have a clear message which method will all=
ow them the best (though maybe not perfect) interoperability. Also, I perso=
nally do not have a preference which of the methods becomes MTI.<br>
<br>
It is common at the IETF to say that &quot;there is no IETF police&quot;, i=
n other words if you choose to not implement an MTI protocol/feature, nobod=
y is going to come after you and punish you. It is between you and your mar=
ket. I fully expect some of the WG participants to only implement the non-M=
TI method.<br>
<br>
We can absolutely ask the incoming AD for more guidance in this area.<br>
<br>
I think keeping the two methods within the same document will speed up and =
simplify the process, compared to running two docs in parallel. They do hav=
e enough commonalities.<br>

We just finished having that exact argument over SET. The apparent consensu=
s was that interoperability across profiles was not desired. I would like t=
o see the working group to discuss whether or not profilers and implementer=
s expect or want interoperable delivery methods, lest we repeat the same de=
bate. There is little point in secevents labeling something MTI if only a s=
mall subset of people will be using it.

Similarly I am concerned about the working group trying to bless one method=
 or the other as MTI in the name of maximizing interoperability without evi=
dence that said method will be used in the majority of deployments, particu=
larly when there are valid technical reasons to favor either one over the o=
ther in different scenarios.

Hi Yaron,

I don't think anyone can argue with the desire for strong interop and less =
complexity.

Wearing our implementor hats, what delivery method would optimally cover al=
l use cases? Do we want a delivery method that in theory can cover most use=
 cases, but it is suboptimal for many of them? How would a mobile or IoT de=
vice use the current PUSH or POLL methods?

We are not talking about alternative delivery methods for the same use case=
, but different methods for each separate use case. I totally agree that as=
 a workinggroup we should support one method per use case, for example one =
method for HTTP receivers sitting behind firewalls. I am using "use case" i=
n a generic way, more like "profile".

Why declare one method as MTI when it is clear that it will not work for ma=
ny use cases and that implementors for those use cases will be forced to ig=
nore the MTI?

Regarding the current delivery draft, why do you think that keeping the two=
 methods together is beneficial? The overlap between the two is minimal. He=
re are the reasons why I think the draft should be split:

1. The two methods have different maturity levels. The PUSH method is alrea=
dy implemented and more implementation will come online soon. The POLL meth=
od has no implementation yet, as far as I know. By keeping them together we=
 hold back one and put pressure to rush the other. That's lose-lose.

2. With two methods in one drafts it is very ambiguous what is MTI. With tw=
o separate drafts each implemetor can chose what works for their use cases.=
 Interop will work out based on use cases, I don't think we have to force i=
t.

The clear message for implementors two years from now would be a clear desc=
ription for each method as to what use cases it is applicable to. No confus=
ion at all, if you are behind a firewall then POLL is your only option. If =
you are delivering to IoT then whatever method works for that use case (we =
don't have one yet).

I asked about a meta-document from a practical point of view.. How/where wi=
ll the MTI delivery method be defined? Same with IETF police, maybe you mis=
understood. I am not worried about implementors disregarding recommendation=
s. Since the unit for specifications are RFCs, how can some RFC be declared=
 as MTI? In what context? Again, from a practical editorial point of view.

Speaking to one draft I worked on where we faced this decision, PKCE Sectio=
n 4.2<https://tools.ietf.org/html/rfc7636#section-4.2> defined two methods =
to transform the code challenge, plain text (no transformation), and SHA256=
.

"S256" is declared as MTI in the spec, and "plain" is not. In this case we =
actually say "Mandatory to Implement", but gating SHA256 with a "MUST" and =
the "plain" with a "MAY" would have achieved the same effect.

I advocated for making S256 MTI (when I first reviewed the draft, both were=
 given equal weighting) so that native app clients would not need to perfor=
m discovery on the server to work out which method they can use (and provid=
e additional API methods for the developer to specify the transform for ser=
vers that don't support discovery). Since SHA256 is MTI, all native app cli=
ents can rely on it being implemented.  And that's what AppAuth does, it ha=
s no support for "plain", and doesn't bother with doing discovery on the PK=
CE method, which greatly simplified the implementation (and it's completely=
 seamless to users of AppAuth). As we required MTI on the more secure optio=
n of the two, this also resulted in more secure implementations by default.

YMMV - but that's what we did in that case :-)


Guidance would be very useful IMO.

Thanks,
Marius

It is common at the IETF to say that "there is no IETF police", in other wo=
rds if you choose to not implement an MTI protocol/feature, nobody is going=
 to come after you and punish you. It is between you and your market. I ful=
ly expect some of the WG participants to only implement the non-MTI method.

We can absolutely ask the incoming AD for more guidance in this area.

I think keeping the two methods within the same document will speed up and =
simplify the process, compared to running two docs in parallel. They do hav=
e enough commonalities.

Thanks,

    We held a couple of brief sessions over the last couple days.

    We talked about the issue of breaking up the delivery document,
    multiple delivery methods, and optionality.

    Some observations:

    1. Yaron indicated that the IETF will likely require one method be
    MTI (mandatory to implement).


It would be very useful to point to other working groups and specs where th=
is was the case.

What is the mechanism by which a specific delivery method is made MTI? Whic=
h meta document specifies that?

What happens if a provider is not implementing the MTI delivery method? Wha=
t does that exactly mean?

Just trying to understand what the process is..


    While PUSH has better scale (because it does not need HTTP Long
    Polling), the POLL method has broader utility due to the presence of
    receivers with firewalls, gateways (IoT devices), or are mobile
    applications that cannot implement endpoints to receive HTTP POSTs.


To me it is very unlikely that IoT or mobile devices will use POLL (or PUSH=
). They will need some other delivery methods appropriate for their archite=
cture. Having the current PUSH or POLL mandatory for these cases does not m=
ake sense to me,


    2.  If POLL is chosen as the MTI method, many will still likely
    prefer PUSH and so that will likely get implemented sooner by some


Many will simply not implement POLL if what they need is PUSH, and vice ver=
sa. Again, I don't see how the working group can pick any delivery method a=
nd make it MTI. And MTI in what context?

Can we escalate this issue within IETF to get guidance?



    3.  There was a general feeling that the delivery draft should stay
    as one draft.


I don't see how that is helping, but if implementors can chose either PUSH =
or POLL from the current draft then that's fine. But in that case splitting=
 should also be acceptable.



    Annabelle will present her recommendations at the formal meeting on
    Friday where we can get broader input.

    Thanks everyone.

any meta-document as far as I can tell. Just think of implementers that are=
 not part of the WG, and just read the RFCs two years from now. They need t=

 will allow them the best (though maybe not perfect) interoperability. Also=
, I personally do not have a preference which of the methods becomes MTI.<b=

<br>
It is common at the IETF to say that &quot;there is no IETF police&quot;, i=
n other words if you choose to not implement an MTI protocol/feature, nobod=
y is going to come after you and punish you. It is between you and your mar=
ket. I fully expect some of the WG participants
 to only implement the non-MTI method.<br>
<br>
We can absolutely ask the incoming AD for more guidance in this area.<br>
<br>
I think keeping the two methods within the same document will speed up and =
simplify the process, compared to running two docs in parallel. They do hav=

&nbsp; &nbsp; Some observations:<br>

&nbsp; &nbsp; 1. Yaron indicated that the IETF will likely require one meth=

&nbsp; &nbsp; MTI (mandatory to implement).<br>
<br>
<br>
It would be very useful to point to other working groups and specs where th=
is was the case.<br>
<br>
What is the mechanism by which a specific delivery method is made MTI? Whic=

<br>
What happens if a provider is not implementing the MTI delivery method? Wha=
t does that exactly mean?<br>
<br>
</span>Just trying to understand what the process is..<span><br>
<br>
<br>
&nbsp; &nbsp; While PUSH has better scale (because it does not need HTTP Lo=
ng<br>
&nbsp; &nbsp; Polling), the POLL method has broader utility due to the pres=
ence of<br>
&nbsp; &nbsp; receivers with firewalls, gateways (IoT devices), or are mobi=
le<br>
&nbsp; &nbsp; applications that cannot implement endpoints to receive HTTP =
POSTs.<br>
<br>
<br>
To me it is very unlikely that IoT or mobile devices will use POLL (or PUSH=
). They will need some other delivery methods appropriate for their archite=
cture. Having the current PUSH or POLL mandatory for these cases does not m=
ake sense to me,<br>
<br>
<br>
&nbsp; &nbsp; 2.&nbsp; If POLL is chosen as the MTI method, many will still=
 likely<br>
&nbsp; &nbsp; prefer PUSH and so that will likely get implemented sooner by=
 some<br>
<br>
<br>
Many will simply not implement POLL if what they need is PUSH, and vice ver=
sa. Again, I don't see how the working group can pick any delivery method a=
nd make it MTI. And MTI in what context?<br>
<br>
Can we escalate this issue within IETF to get guidance?<br>
<br>
<br>
<br>
&nbsp; &nbsp; 3.&nbsp; There was a general feeling that the delivery draft =
should stay<br>
&nbsp; &nbsp; as one draft.<br>
<br>
<br>
I don't see how that is helping, but if implementors can chose either PUSH =
or POLL from the current draft then that's fine. But in that case splitting=
 should also be acceptable.<br>

Thanks William.

Yes, if both delivery methods are described in one draft then the draft
maybe declare one MTI and the other not. In this case the MTI is in the
context of the draft or RFC, in order to claim that you support the RFC you
have to respect the MTI.

But if the delivery methods are in separate drafts then I don't see how
that can be done. You are claim to support one RFC or the other.

This is all technical details on how MTI can be specified. The question if
an MTI for delivery methods is desirable or not is totally different.

<br>
The decision about whether we need to have an MTI protocol and which one it=
 should be is up to the WG consensus, like everything else. But with my WG =
chair hat on, it is my strong conviction that we need to have one MTI metho=
d to encourage interoperability and reduce fragmentation. This is based on =
my IETF experience, and not on any meta-document as far as I can tell. Just=
 think of implementers that are not part of the WG, and just read the RFCs =
two years from now. They need to have a clear message which method will all=
ow them the best (though maybe not perfect) interoperability. Also, I perso=
nally do not have a preference which of the methods becomes MTI.<br>
<br>
It is common at the IETF to say that &quot;there is no IETF police&quot;, i=
n other words if you choose to not implement an MTI protocol/feature, nobod=
y is going to come after you and punish you. It is between you and your mar=
ket. I fully expect some of the WG participants to only implement the non-M=
TI method.<br>
<br>
We can absolutely ask the incoming AD for more guidance in this area.<br>
<br>
I think keeping the two methods within the same document will speed up and =
simplify the process, compared to running two docs in parallel. They do hav=
e enough commonalities.<br>

Thanks,<br>

=C2=A0 =C2=A0 We held a couple of brief sessions over the last couple days.=
<br>
<br>
=C2=A0 =C2=A0 We talked about the issue of breaking up the delivery documen=
t,<br>
=C2=A0 =C2=A0 multiple delivery methods, and optionality.<br>
<br>
=C2=A0 =C2=A0 Some observations:<br>
<br>
=C2=A0 =C2=A0 1. Yaron indicated that the IETF will likely require one meth=
od be<br>
=C2=A0 =C2=A0 MTI (mandatory to implement).<br>
<br>
<br>
It would be very useful to point to other working groups and specs where th=
is was the case.<br>
<br>
What is the mechanism by which a specific delivery method is made MTI? Whic=
h meta document specifies that?<br>
<br>
What happens if a provider is not implementing the MTI delivery method? Wha=
t does that exactly mean?<br>
<br></span>
Just trying to understand what the process is..<span><br>
<br>
<br>
=C2=A0 =C2=A0 While PUSH has better scale (because it does not need HTTP Lo=
ng<br>
=C2=A0 =C2=A0 Polling), the POLL method has broader utility due to the pres=
ence of<br>
=C2=A0 =C2=A0 receivers with firewalls, gateways (IoT devices), or are mobi=
le<br>
=C2=A0 =C2=A0 applications that cannot implement endpoints to receive HTTP =
POSTs.<br>
<br>
<br>
To me it is very unlikely that IoT or mobile devices will use POLL (or PUSH=
). They will need some other delivery methods appropriate for their archite=
cture. Having the current PUSH or POLL mandatory for these cases does not m=
ake sense to me,<br>
<br>
<br>
=C2=A0 =C2=A0 2.=C2=A0 If POLL is chosen as the MTI method, many will still=
 likely<br>
=C2=A0 =C2=A0 prefer PUSH and so that will likely get implemented sooner by=
 some<br>
<br>
<br>
Many will simply not implement POLL if what they need is PUSH, and vice ver=
sa. Again, I don&#39;t see how the working group can pick any delivery meth=
od and make it MTI. And MTI in what context?<br>
<br>
Can we escalate this issue within IETF to get guidance?<br>
<br>
<br>
<br>
=C2=A0 =C2=A0 3.=C2=A0 There was a general feeling that the delivery draft =
should stay<br>
=C2=A0 =C2=A0 as one draft.<br>
<br>
<br>
I don&#39;t see how that is helping, but if implementors can chose either P=
USH or POLL from the current draft then that&#39;s fine. But in that case s=
plitting should also be acceptable.<br>
<br>
<br>

Leif, I believe you raised this issue at a past meeting. Do you have any
thoughts?

"exp" does not apply to the event(s), it applies to the envelope, same as
"iat". Here is the definition from RFC 7519:
"The "exp" (expiration time) claim identifies the expiration time on or
after which the JWT MUST NOT be accepted for processing."

Transmitters don't "invent" the value, the value falls out of re-try
parameters and the specific delivery method used. Are IdPs inventing the
exp in an Id Token?

Also, "exp" in a SET should probably be "RECOMMENDED" and not "MUST".

For sure, but an exp claim makes the whole process more secure. A receiver
may decide to cache for 2 minutes (and not accept SETs older than 2
minutes, hopefully), but a transmitter my keep re-trying to send events for
10 minutes. Many things can go wrong if exp is not present.

Yaron just raised concerns about interop, pushing this issue to profiles is
not helping interop IMO.

Given the discussion around having a single MTI method for SET Delivery, =
and consensus issue emerging on choosing PUSH or PULL for MTI, this =
draft is submitted as a *compromise* which merges both methods into a =
single =E2=80=9Csymmetric=E2=80=9D approach capable of addressing both =
communities concerns and all use cases. The draft has 3 examples which =
show how PULL-only, PUSH-only, and how PUSH-PULL may be accomplished =
using the unified approach.

Whether =E2=80=9Cpushing=E2=80=9D (e.g. from an issuer to a receiver =
HTTP endpoint) or =E2=80=9Cpulling=E2=80=9D (by a receiver from an =
issuer HTTP endpoint), the same transfer and response methods and =
formats are always used.  Because delivery can be either direction or =
both directions, the sender and receiver are free to choose role as HTTP =
Client or Server based on the environmental and network restrictions =
they face.

Where possible, we have kept the protocol signalling and responses the =
same or simpler. Three changes in particular:=20
* Transmitter/receiver terminology is dropped (due to bi-directionality) =
and replaced with HTTP Client vs. HTTP/SSTP Server. (non-normative)
* Both pushers and pullers use the same multi-SET format.  (normative =
change for PUSH)
* The flag maxEvents=3DN is now replaced with a simple boolean =
returnEvents and now also allows the HTTP client to indicate it does not =
want to pull events=20

Previous features and capability(such as multi-threading) =
characteristics have been preserved. For example, error signalling was =
the same for both methods and remains the same.

Tony and I recognize that as separate methods, there could be more =
optimization. For example, in PUSH mode, receivers now have to process a =
JSON structure that contains multiple SETs vs. just parsing one set. We =
considered preserving single-event (application/jwt) format, and could =
still do so. However, having multiple content-types seems to add =
unnecessary complexity and more implementer coding.

I agree with this logic. It's only relevant when multiple alternatives are
documented in a single RFC.  If there are conflicting opinions on which
should be MTI, and they're different enough, perhaps that is an indication
that separate specifications would be better.

Another MTI example: OAuth 2.0 Section 2.3.1
<https://tools.ietf.org/html/rfc6749#section-2.3.1> mandates that servers
support HTTP Basic for client authentication, while also documenting
request-body for clients that are unable to use HTTP Basic Authentication.
AppAuth took advantage of this MTI too, by only authenticating using HTTP
Basic, since it is capable of doing so, and this simplified the API surface
substantially.

Hi Marius,<br>
<br>
The decision about whether we need to have an MTI protocol and which one it=
 should be is up to the WG consensus, like everything else. But with my WG =
chair hat on, it is my strong conviction that we need to have one MTI metho=
d to encourage interoperability and reduce fragmentation. This is based on =
my IETF experience, and not on any meta-document as far as I can tell. Just=
 think of implementers that are not part of the WG, and just read the RFCs =
two years from now. They need to have a clear message which method will all=
ow them the best (though maybe not perfect) interoperability. Also, I perso=
nally do not have a preference which of the methods becomes MTI.<br>
<br>
It is common at the IETF to say that &quot;there is no IETF police&quot;, i=
n other words if you choose to not implement an MTI protocol/feature, nobod=
y is going to come after you and punish you. It is between you and your mar=
ket. I fully expect some of the WG participants to only implement the non-M=
TI method.<br>
<br>
We can absolutely ask the incoming AD for more guidance in this area.<br>
<br>
I think keeping the two methods within the same document will speed up and =
simplify the process, compared to running two docs in parallel. They do hav=
e enough commonalities.<br>
<br>
Thanks,<br>

=C2=A0 =C2=A0 We held a couple of brief sessions over the last couple days.=
<br>
<br>
=C2=A0 =C2=A0 We talked about the issue of breaking up the delivery documen=
t,<br>
=C2=A0 =C2=A0 multiple delivery methods, and optionality.<br>
<br>
=C2=A0 =C2=A0 Some observations:<br>
<br>
=C2=A0 =C2=A0 1. Yaron indicated that the IETF will likely require one meth=
od be<br>
=C2=A0 =C2=A0 MTI (mandatory to implement).<br>
<br>
<br>
It would be very useful to point to other working groups and specs where th=
is was the case.<br>
<br>
What is the mechanism by which a specific delivery method is made MTI? Whic=
h meta document specifies that?<br>
<br>
What happens if a provider is not implementing the MTI delivery method? Wha=
t does that exactly mean?<br>
<br></span>
Just trying to understand what the process is..<span><br>
<br>
<br>
=C2=A0 =C2=A0 While PUSH has better scale (because it does not need HTTP Lo=
ng<br>
=C2=A0 =C2=A0 Polling), the POLL method has broader utility due to the pres=
ence of<br>
=C2=A0 =C2=A0 receivers with firewalls, gateways (IoT devices), or are mobi=
le<br>
=C2=A0 =C2=A0 applications that cannot implement endpoints to receive HTTP =
POSTs.<br>
<br>
<br>
To me it is very unlikely that IoT or mobile devices will use POLL (or PUSH=
). They will need some other delivery methods appropriate for their archite=
cture. Having the current PUSH or POLL mandatory for these cases does not m=
ake sense to me,<br>
<br>
<br>
=C2=A0 =C2=A0 2.=C2=A0 If POLL is chosen as the MTI method, many will still=
 likely<br>
=C2=A0 =C2=A0 prefer PUSH and so that will likely get implemented sooner by=
 some<br>
<br>
<br>
Many will simply not implement POLL if what they need is PUSH, and vice ver=
sa. Again, I don&#39;t see how the working group can pick any delivery meth=
od and make it MTI. And MTI in what context?<br>
<br>
Can we escalate this issue within IETF to get guidance?<br>
<br>
<br>
<br>
=C2=A0 =C2=A0 3.=C2=A0 There was a general feeling that the delivery draft =
should stay<br>
=C2=A0 =C2=A0 as one draft.<br>
<br>
<br>
I don&#39;t see how that is helping, but if implementors can chose either P=
USH or POLL from the current draft then that&#39;s fine. But in that case s=
plitting should also be acceptable.<br>
<br>
<br>
<br>
=C2=A0 =C2=A0 Annabelle will present her recommendations at the formal meet=
ing on<br>
=C2=A0 =C2=A0 Friday where we can get broader input.<br>

I hope neither method will become MTI.

An MTI would work well if the MTI method could potentially cover all
delivery cases, and the other method extends or enhances the MTI with
features. But in the case of HTTP push vs pull, we have two delivery
methods intended to solve different use cases. Designating one of them
MTI is a bit like making apples MTI for oranges.

I don't think anyone can argue with the desire for strong interop and
less complexity.

Wearing our implementor hats, what delivery method would optimally cover
all use cases? Do we want a delivery method that in theory can cover most=

use cases, but it is suboptimal for many of them? How would a mobile or I=
oT
device use the current PUSH or POLL methods?

We are not talking about alternative delivery methods for the same use
case, but different methods for each separate use case. I totally agree
that as a workinggroup we should support one method per use case, for
example one method for HTTP receivers sitting behind firewalls. I am usin=
g
"use case" in a generic way, more like "profile".

Why declare one method as MTI when it is clear that it will not work for
many use cases and that implementors for those use cases will be forced t=
o
ignore the MTI?

Regarding the current delivery draft, why do you think that keeping the
two methods together is beneficial? The overlap between the two is minima=
l.
Here are the reasons why I think the draft should be split:

1. The two methods have different maturity levels. The PUSH method is
already implemented and more implementation will come online soon. The PO=
LL
method has no implementation yet, as far as I know. By keeping them
together we hold back one and put pressure to rush the other. That's
lose-lose.

2. With two methods in one drafts it is very ambiguous what is MTI. With
two separate drafts each implemetor can chose what works for their use
cases. Interop will work out based on use cases, I don't think we have to=

force it.

The clear message for implementors two years from now would be a clear
description for each method as to what use cases it is applicable to. No
confusion at all, if you are behind a firewall then POLL is your only
option. If you are delivering to IoT then whatever method works for that
use case (we don't have one yet).

I asked about a meta-document from a practical point of view.. How/where
will the MTI delivery method be defined? Same with IETF police, maybe you=

misunderstood. I am not worried about implementors disregarding
recommendations. Since the unit for specifications are RFCs, how can some=

two methods to transform the code challenge, plain text (no
transformation), and SHA256.

"S256" is declared as MTI in the spec, and "plain" is not. In this case
we actually say "Mandatory to Implement", but gating SHA256 with a "MUST"=

and the "plain" with a "MAY" would have achieved the same effect.

I advocated for making S256 MTI (when I first reviewed the draft, both

Yes, if both delivery methods are described in one draft then the draft

              <pre wrap=3D"">Hi Marius,

The decision about whether we need to have an MTI protocol and which
one it should be is up to the WG consensus, like everything else. But wit=
h
my WG chair hat on, it is my strong conviction that we need to have one M=
TI
method to encourage interoperability and reduce fragmentation. This is
based on my IETF experience, and not on any meta-document as far as I can=

tell. Just think of implementers that are not part of the WG, and just re=
ad
the RFCs two years from now. They need to have a clear message which meth=
od
will allow them the best (though maybe not perfect) interoperability. Als=
o,
I personally do not have a preference which of the methods becomes MTI..

It is common at the IETF to say that "there is no IETF police", in
other words if you choose to not implement an MTI protocol/feature, nobod=
y
is going to come after you and punish you. It is between you and your
market. I fully expect some of the WG participants to only implement the
non-MTI method.

We can absolutely ask the incoming AD for more guidance in this area.

I think keeping the two methods within the same document will speed up
and simplify the process, compared to running two docs in parallel. They =
do
have enough commonalities.

Thanks,
        Yaron

    We held a couple of brief sessions over the last couple days.

    We talked about the issue of breaking up the delivery document,
    multiple delivery methods, and optionality.

    Some observations:

    1. Yaron indicated that the IETF will likely require one method be
    MTI (mandatory to implement).


It would be very useful to point to other working groups and specs
where this was the case.

What is the mechanism by which a specific delivery method is made MTI?
Which meta document specifies that?

What happens if a provider is not implementing the MTI delivery
method? What does that exactly mean?

Just trying to understand what the process is..


    While PUSH has better scale (because it does not need HTTP Long
    Polling), the POLL method has broader utility due to the presence
of
    receivers with firewalls, gateways (IoT devices), or are mobile
    applications that cannot implement endpoints to receive HTTP POSTs.


To me it is very unlikely that IoT or mobile devices will use POLL (or
PUSH). They will need some other delivery methods appropriate for their
architecture. Having the current PUSH or POLL mandatory for these cases
does not make sense to me,


    2.  If POLL is chosen as the MTI method, many will still likely
    prefer PUSH and so that will likely get implemented sooner by some


Many will simply not implement POLL if what they need is PUSH, and
vice versa. Again, I don't see how the working group can pick any deliver=
y
method and make it MTI. And MTI in what context?

Can we escalate this issue within IETF to get guidance?



    3.  There was a general feeling that the delivery draft should stay
    as one draft.


I don't see how that is helping, but if implementors can chose either
PUSH or POLL from the current draft then that's fine. But in that case
splitting should also be acceptable.



    Annabelle will present her recommendations at the formal meeting on
    Friday where we can get broader input.

    Thanks everyone.

Thank you Valery for taking the minutes. All, please let us know if 
anything is incorrect or missing.

In addition, we had a series of hums on the SET Delivery draft. Per IETF 
process, we need to validate them on the list. So if you weren't in the 
room and you have a major objection to the results of these hums, please 
speak up. I do suggest that before doing so, you review the actual 
recorded meeting: https://www.youtube.com/watch?v=r0hbpQqsN6s.

IETF 101 London Friday 23 March 2018 9:30 - 11:30

[Yaron] (WG status update, agenda bashing)
[Annabelle] asks for 10 minutes for discussion

[Mike] (presents Security Event Token draft update)

[Annabelle] (presents SET Token delivery using HTTP draft)
[Mike] Microsoft needs for both POLL and PUSH
[Phil] Redefining smth in HTTP may cause problems
[William] Return codes are only for browsers to display messages for users
[Phil] It's needed for resending in case of error (?)
[Annabelle] What is MTI - push or poll?
[Phil] With PUSH  happened immediately...
[Leif] What is MTI for server or for client?
[William] Each option has an explicit use case
[Yaron (as chair)] We need to have only one preferred option
[Phil] There are very different cases
[Phil] Push is simple, but in terms of applicability it's not a long 
term use case
[Annabelle] There use cases for both
[Phil] Take two and then abandon one
[William] Why does the chair require a single MTI
[Leif] It's from chair's experience, WG consensus needed
[William] We have use cases for both
[Mike] Procedurally it's better to keep both methods in one draft
[Yaron] Having two methods complicates the description which method is 
for which situation etc.
[William] Still have interoperability issue for receiver
[Yaron] Need to resolve this
[Leif] WG should decide
[Ben as AD] If the WG doesn't select a single method the IESG would 
probably object
[Annabelle] SET will probably be profiled for different use cases
[Yaron] Is going to make hums about selecting a single delivery method 
and whether we need to split the draft
[John] What is hum about - mandatory to implement or to deploy?
[Leif] We should analyze scenarios
[Annabelle] The protocol are unidirectional, so MTI for 
transmitter/receiver is problematic
[Justin] No negotiation, either it is or not, MTI for the receiver is
dictated by what the receiver supports
[Phil] They both must be able HTTP, the roles can be changed
[Leif] Confusion between MTI and to deploy, a good question - select MTI 
for transmitter
[Annabelle] Every transmitter should have both
[Tero] Minimal implementation requires one, bigger may have both, single 
MTI is better then two for limited devices
[Annabelle] IoT implementers have special requirement
[William] They are application specific, we expected profile this
[Yaron] Hum if we need a single MTI for transmitter - silence
Later edit: Clearly no support for a single MTI.
[Justin] Hum must be for multiple discrete options
[Yaron] Hum on use cases for two methods - some hums
[Yaron] Hum if both should be MTI - some hums
[Yaron] Hum if should not specify MTI - some hums
Later edit: room was split between two MTIs and no MTIs.
[Annabelle] We should split the spec
[Justin] Agree to split the spec
[Justin] I hummed for both MTI for transmitter, because they are not 
usually constrained
[Annabelle] SET is possibly to be used w/o HTTP, this is only MTI for 
those using HTTP; both MTI is problematic because implementers will do 
unnecessary stuff
[William] If both are MTI, we need 2 specs
[John] Splitting the spec is the best way
[Mike] If split, then the information for developers will be duplicated
[Ben] Why single document better (?)
[Mike] My experience with JOSE
[Annabelle] Significant overlap between documents is SET, otherwise 
little commonality
Later edit: existing editors volunteered to take Push-specific doc, 
Annabelle and Mike volunteered to work on Poll.
[from jabber] Little commonality between two methods
[Mike] We'll do both, we have use cases for both
[Yaron] Hum if split documents - some long hums
[Yaron] Hum if one document - some hums
[Yaron] Room is in favor of splitting the documents
[Yaron] Wrap up: no MTI, split the document into two, transmitter 
implements either or both

[Annabelle] (presenting Subject Identifier Types)
[Mike] 3rd party specifications cannot establish IANA registry
[Leif] IANA Expert?
[Ben] FCFS, doesn't need Expert, or specification required
[Leif] I support this idea
[William] I also support
[Yaron] Any objections to adopt this document? No objections, publish as 
WG document

[Annabelle] Expiration ("exp") claim is not recommended; however it has 
some value
[Mike] It's a layering violation; problems with caching
[Annabelle] We're not talking about caching, you don't want to grow 
anti-replay database forever, having expiration helps
[Phil] The past doesn't expire, it's up to receiver how to use it, 
caching doesn't make sense
[Yaron] What about replay protection?
[Mike] JTI helps to detect replay (?) [from jabber] Transport should 
deal with replay
[John] Expiry is expected to mean that token should not be processed 
after that, it's not an indication that information is no longer valid
[Mike] It must not be mandatory
[Annabelle] Currently the draft says it's not recommended
[Mike] We have to allow it to be optional because of the need to 
distinguish from access tokens.
[Ben] Some use case when processing expired token (?)
[John] Have an explicit expire for JTI, there are other solutions
[Phil] I prefer to add a new attribute to SET, not changing ...
[Yaron] The document in LC, smaller changes are OK without blocking the 
doc's progress.
[Phil] Replay and caching are different for PUSH and POLL, prefer to see 
in HTTP header
[Brian] Expiration is not necessary, receiver has policy to follow
[Annabelle] No-one is advocating using exp for caching
[from jabber] JTI expiration belongs to JTI not to transport
[Yaron] We're not ready to have hum, room thinks there is an issue, 
please work through it on the list.

[Phil] Presents his SSTP Delivery draft - symmetric transport protocol, 
parameters used in requests and response are same
[Phil] We would change optionality from two methods to a single one, may 
be a compromise
[Yaron] The protocol was only published yesterday, so we are not ready 
to discuss now.

[Meeting adjourned.]

There was some other discussion i believe it was about status 400 which info=
rms the client of jwt related error and that using status 403 would not let c=

Reviewer: Russ Housley
Review result: Has Issues

I reviewed this document as part of the Security Directorate's ongoing
effort to review all IETF documents being processed by the IESG.  These
comments were written primarily for the benefit of the Security Area
Directors.  Document authors, document editors, and WG chairs should
treat these comments just like any other IETF Last Call comments.

Document: draft-ietf-secevent-token-07
Reviewer: Russ Housley
Review Date: 2018-03-27
IETF LC End Date: unknown
IESG Telechat date: 2018-05-10

Summary: Has Issues

Process concern

A request for a telechat review of draft-ietf-secevent-token was
assigned to me.  However, there has not yet been an IETF Last Call
announced for this document.


Major Concerns

All of the examples in Section 2.1 are non-normative.  Instead of
staying that in each of the subsections, please add some text at the
top of Section 2.1 that says so.

I do not understand the first paragraph of Section 3.  I think you are
trying to impose some rules on future specifications that use SET to
define events.  Please reword.


Minor Concerns

The Abstract says:

   ...  This statement of fact
   represents an event that occurred to the security subject.  In some
   use cases, the security subject may be a digitial identity, but SETs
   are also applicable to non-identity use cases.  ...

Please correct the spelling of digital identity.

I do not think this tells the reader when they might want to employ this
specification.  The following sentence from the Introduction does a
better job:

   This specification is scoped to security and identity related events.


In Section 2, the last bullet on page 5 talks about the "events" JSON
object.  The last sentence caught me by surprise, and I had to read it a
few times to figure out the intent.  The events object cannot be "{}",
but the payload for an event in that object can be "{}".  I think that
a MUST statement about there being at least one URI string value would
have helped me.

Thanks for the review, and for pointing out the process nit.
Getting on a telechat is pretty hard at the moment due to the large
spike in documents we saw prior to the IESG cutover.  I should still
have time to complete my AD review and issue the IETF LC with time
to spare before 2018-05-10, though.

Authors, please feel free to address Russ's comments in a new
revision if you can do so before the IETF LC is issued.

Thanks,

Ben

Regarding the hums, I think they may be premature. In part, because there is=
 a unifying draft proposal available now.=20

When we formed the group the sole purpose was a common format and a single d=
elivery draft for all cases.=20

Several ietf people complained in Argentina about yet another pub sub system=
 the ietf does not need.=20

Another comment was made not to follow the route stix/taxii made in developi=
ng multiple incompatible methods of delivery.=20

If we split the draft we will have 3 methods not two(including Backchannel).=
=20

I worry this will lead to delay from rejection down the road. This should be=
 clarified first.=20

I worry with multiple methods, profilers will develop their own undermining t=
he point of this work.=20

Maybe I stand alone here, but I think splitting is a mistake.=20

I agree with Phil that having separate push and pull delivery drafts would =
be a mistake.  Many participants will end up implementing both modalities. =
 Having them both in one draft will help keep them as common as possible - =
preventing unnecessary and possibly unintended drift between them.

Also, as I said at the microphone in London, I think we'll have a much easi=
er time with the IESG taking one draft forward with two closely related del=
ivery modalities defined, rather that two different delivery drafts.  I fea=
r that if we try to get approval for two drafts, we might receive DISCUSS f=
eedback saying "pick one".

For what it's worth (and to inform people who weren't in the room), my pers=
onal sense was that the hums weren't conclusive.  Most of them had signific=
ant portions of people humming for both positions.  In short, my (personal)=
 sense was there wasn't clear consensus demonstrated to split the delivery =
draft.  I think the topic needs more discussion on the list.

				Best wishes,
				-- Mike

Subject: Re: [Id-event] SecEvent draft minutes - IETF-101 (London)

Regarding the hums, I think they may be premature. In part, because there i=
s a unifying draft proposal available now.=20

When we formed the group the sole purpose was a common format and a single =
delivery draft for all cases.=20

Several ietf people complained in Argentina about yet another pub sub syste=
m the ietf does not need.=20

Another comment was made not to follow the route stix/taxii made in develop=
ing multiple incompatible methods of delivery.=20

If we split the draft we will have 3 methods not two(including Backchannel)=
.=20

I worry this will lead to delay from rejection down the road. This should b=
e clarified first.=20

I worry with multiple methods, profilers will develop their own undermining=
 the point of this work.=20

Maybe I stand alone here, but I think splitting is a mistake.=20

I would rather have people who were NOT in the room chime in regarding 
the hums. Otherwise this is the sense of the group. I don't see value in 
reopening a decision just weeks after it was made.

Thanks,

Most of them had significant portions of people humming for both positions.  In short, my (personal) sense was there wasn't clear consensus demonstrated to split the delivery draft.  I think the topic needs more discussion on the list.
