We got several supports and no objections, so it is concluded that the draf=
t
is adopted as an ACE WG item, with the change that we remove the "web=A1=B0 fro=
m
the name.

Authors: please resubmit the current draft as
draft-ietf-ace-cbor-token-00.txt; we will start processing further changes
in the WG process.(If you already know about technical issues, please use
the WG tracker for now; editorial issues might be tracked easier on github.=
)

We will also add this item in our ACE charter.

Kind Regards
Kepeng (ACE co-chair)

=D6=F7=CC=E2:  [Ace] Call for adoption for draft-wahlstroem-ace-cbor-web-token-00

To: ACE WG
Cc: OAuth and COSE WG

Hello all,

This note begins a Call For Adoption for
draft-wahlstroem-ace-cbor-web-token-00 [1]
to be adopted as an ACE working group item, and added in the charter.
The call ends on April 22, 2016.

Keep in mind that adoption of a document does not mean the document
as-is is ready for publication. It is merely acceptance of the
document as a starting point for what will be the final product
of the ACE working group. The working group is free to make changes to
the document according to the normal consensus process.

Please reply on this thread with expressions of support or opposition,
preferably with comments, regarding accepting this as a work item.

Note that this email was also copied to OAuth and COSE WG, in order to
get input from wider audience.

Thanks,

Kind Regards
Kepeng (ACE co-chair)

> draft-ietf-ace-cbor-token-00.txt; 

For the record, I do not think that ACE has a claim on the term "CBOR
Token".  While the term token is not used in RFC 7049, there are many
tokens that could be expressed in CBOR or be used in applying CBOR to a
problem.

ACE CBOR Token is fine, though.

Or keep the CBOR Web Token (CWT) for two major reasons:
- To show the very close relationship to JWT. It relies heavily on JWT and
it's iana registry. It is essentially a JWT but in CBOR/COSE instead of
JSON/JOSE.
- I would not say that JWT is the only format that works for the web, and
it's even used in other, non-traditional, web protocols. That means I don't
have a problem with the W in CWT at all. Why would JSON be the only web
protocol?

Then we also have one smaller (a lot smaller) reason, it's the fact that it
can be called "cot" just like JWT is called a "jot" and I figured that our
"cozy chairs" would very much like that fact because then it's essentially
a "cozy cot" :)

You=E2=80=99re missing my original complaint: Until this token can be =
directly encoded into web technologies, like HTTP headers and HTML =
pages, then it has no business being called a =E2=80=9CWeb=E2=80=9D =
anything. As it is, it=E2=80=99s a binary encoding that would need an =
additional wrapper, like base64url perhaps, to be placed into web =
spaces. It can be used in CoAP and native CBOR structures as-is, which =
is what it=E2=80=99s designed to do.=20

The =E2=80=9Cweb=E2=80=9D part of JWT is very important. A JWT can be =
used, as-is, in any part of an HTTP message: headers, query, form, etc. =
It can also be encoded as a string in other data structures in just =
about any language without any additional transformation, including =
HTML, XML, and JSON. This makes the JWT very =E2=80=9Cwebby=E2=80=9D, =
and this is a feature set that this new token doesn=E2=80=99t share. =
Ergo, it has no business being called a =E2=80=9Cweb=E2=80=9D token =
regardless of its heritage.=20

Both CBOR Token and COSE Token are fine with me.=20

That's a very value scenario actually. Even so that it should actually be
handled in the draft.
Scenario: In the continuum of large and small devices an unconstrained
client and AS goes through the hoops of issuing a token using standard
(HTTP/JSON). The Resource Server however is constrained and would very much
like a CWT when it communicates with the Client. That means that in the AS
to Client response from the token endpoint the binary token should actually
be wrapped by base64url.
I can definitely see that being added to the draft.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the CBOR Object Signing and Encryption of the IETF.

        Title           : CBOR Encoded Message Syntax
        Author          : Jim Schaad
	Filename        : draft-ietf-cose-msg-12.txt
	Pages           : 112
	Date            : 2016-05-12

Abstract:
   Concise Binary Object Representation (CBOR) is data format designed
   for small code size and small message size.  There is a need for the
   ability to have the basic security services defined for this data
   format.  This document specifies processing for signatures, message
   authentication codes, and encryption using CBOR.  This document also
   specifies a representation for cryptographic keys using CBOR.


The IETF datatracker status page for this draft is:
https://datatracker.ietf.org/doc/draft-ietf-cose-msg/

There's also a htmlized version available at:
https://tools.ietf.org/html/draft-ietf-cose-msg-12

A diff from the previous version is available at:
https://www.ietf.org/rfcdiff?url2=draft-ietf-cose-msg-12


Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.

Internet-Drafts are also available by anonymous FTP at:

Given that we are not being an online protocol, This has not been done.  This is the same decision as was made for the JOSE version of the same algorithm

I believe that this draft represents all of the decisions that were taken at
BA.  I have been through the draft a couple of times to look for problems
and I believe that it is now ready for a working group last call.

Thanks, Jim.

Everyone, please look over the current draft as well as the issues list =
(most of which have been marked =E2=80=9CComplete=E2=80=9D, or otherwise =
refer to separate documents).=20

<https://github.com/cose-wg/cose-issues/issues>

We=E2=80=99ll give people two weeks starting today to look things over =
and bring up any showstoppers, then we=E2=80=99ll start the WGLC in =
earnest.

>=20

We do not have a current method of carrying certificates in a COSE =
message at this time.  When we were discussing things, it was presumed =
and confirmed that while certificates may be used, they were going to be =
pre-provisioned in some manner.  The additional overhead associated with =
carrying certificates was not considered to be part of the target =
environment.

That said, for pre-provisioned certificates one would place the SPKI =
field into the KID field of a message.=20

If one really wants to carry certificates, then one would need to define =
a new header field that allowed for one or more certificates to be =
carried as part of the message.  One might also wish to provide for OCSP =
responses to be carried as well for long term messages and good time =
capabilities in order to ease revocation checking.  I do recognize that =
many of the situations you are looking at would probably not do =
revocation checking but it might be reasonable to allow for the ability =
in the future.

I remember that you told me about this and I did intend to deal with the =
first case, but I forgot to write it down and missed it. =20

I thought that I had dealt with the second case, but I cannot seem to =
find the text at the moment so it might have been lost.  I will look for =
it and see if I am just missing it or if the text got lost and needs to =
be re-added.

I have two students who are in the process of adapting Jim's Cose-C lib=20
to a CC2358 platform. However I doubt that this will be in good enough=20

As announced two weeks ago, since we haven't seen any showstoppers or 
complaints on recently completed issues, the messages document is now in 
WGLC. We expect this LC to run for two weeks.

Everyone, please review the current document and reply to the list with 
your reviews. Even if it's "I read it and everything looks good to me", 
that's helpful information for us to have in order to move things forward.

Mike,

I think it's a little ridiculous to expect a fully two-week window to be 
open to the exact minute from which it was specified in email, a medium 
which is prone to delays and delivery oddities at the best of times. The 
review period was in fact two weeks long and was closed on the calendar 
day specified. I'm sorry that this confused you. Maybe I'll start saying 
"fortnight" instead so that people realize the implied loose 
granularity? Regardless, in case anyone else is still confused: the WGLC 
will close sometime on June 10. You've got almost two weeks, people, 
don't put off your reviews until the last second.

As for the present: Whatever issues you may have discovered during your 
review on the last day can still be brought up. WGLC isn't the *end* of 
comments, it's a period *for* comments. You can comment on closed issues 
without my reopening anything, and thus I will not be reopening any 
issues. However, as the document is currently in WGLC, I would prefer if 
you bring the review to the list as requested in the WGLC email.

If you've got something to say about COSE then now is a really, really 
good time to say it.

Thank you,

  -- Justin, your COSE chair

                      Abstract:<br>
                        Concise Binary Object Representation (CBOR) is
                      data format designed<br>
                        for small code size and small message size.
                       There is a need for the<br>
                        ability to have the basic security services
                      defined for this data<br>
                        format.  This document specifies processing for
                      signatures, message<br>
                        authentication codes, and encryption using CBOR.
                       This document also<br>
                        specifies a representation for cryptographic
                      keys using CBOR.<br>
                      <br>
                      <br>
