Remember that, even though this will now go to the printers, there is still some potential for changes. Conflicts that meet the eye: COSE/TEEP stays; ROLL/SUIT/DINRG and 6TISCH/ACE are maybe slightly less annoying. LAKE and LOOPS have been disentangled, thank you. I have put in some side meetings, but that picture may still change (and I don't understand the timezone logic of that system, so it may be all wrong). All times are EDT (Eastern Daylight Time) =3D=3D UTC -4 hours. (Pure UTC times at https://datatracker.ietf.org/meeting/agenda-utc are useful for those who want to listen from remote.)

Title : Trusted Execution Environment Provisioning (TEEP) Architecture Authors : Mingliang Pei Hannes Tschofenig David Wheeler Andrew Atyeo Liu Dapeng Filename : draft-ietf-teep-architecture-03.txt Pages : 37 Date : 2019-07-08 Abstract: A Trusted Execution Environment (TEE) is designed to provide a hardware-isolation mechanism to separate a regular operating system from security-sensitive application components. This architecture document motivates the design and standardization of a protocol for managing the lifecycle of trusted applications running inside a TEE.

Hi all,

 

We put together a draft about what I would call vers= ion 2 of the OTrP protocol. Why version 2?

 

As you know, there is some work in Global Platform s= tandardizing the version we have been working on so far in the group.

However, based on the design decisions made so far w= e are breaking backwards compatibility. We need to distinguish the two vers= ions somehow.

 

Did we just create a problem with this approach? Not= really! We are trying to cover a much broader set of use cases than envisi= oned with the initial version of OTrP.

When the work on OTrP started the primary use case w= as about mobile phones and tablets. We added other types of TEEs, such as S= GX and at the last hackathon people talked about RISC-V-based TEEs. We now = also want to cover IoT scenarios.

Technology has also evolved with the work by Microso= ft on their Open Enclave SDK and with TrustZone for v8-M. The IETF has also= started various standardization activities, which we are leveraging.

 

So, what’s in that new draft – an indivi= dual submission at this point in time:

 

  • Removal of the security domain management concept (although this can be add= ed as an extension)
  • Encoding agnostic description using CDDL (although it focuses on CBOR/COSE = because of my limited understanding of CDDL)
  • Added CBOR/COSE encoding (the earlier version of OTrP only supported JSON/J= OSE)
  • Terminology alignment with the TEEP architecture draft
  • Support of attestation via the RATS/EAT specification
  • Support for software management via the SUIT manifest
  • Added better extension management
  • Removed a lot of redundant text (the text is already in the architecture do= cument and there is no point in repeating it again)

 

Re-using other IETF specifications and removing feat= ures and optimizations made this new version much simpler. I also believe i= t will be much, much easier to implement.

 

There are some questions that surfaced during the wo= rk on this draft, such as whether we want to support multiple encodings for= this protocol. I plan to discuss these topics at the upcoming IETF meeting= (if I get a presentation slot)

 

I hope you find this interesting and I am looking fo= rward to see your feedback!

 

Ciao

Hannes

I plan to discuss these topics at the upcoming IETF meeting (if I get a presentation slot) I have said it before and I say it again: By separating the API from the Protocol and rather use a session-based scheme you get a cleaner and more powerful system [*] in the end. Yeah, the initial task will be 30-50% bigger but that difference is zeroed out when you have both protocol encodings in place.

BTW, I never understood the point making an IETF copy (= it was?) of another standard. Actually, it was the other way around. > I have said it before and I say it again: By separating the API from the = Protocol and rather use a session-based scheme you get a cleaner and more p= owerful system [*] in the end. Yeah, the initial task will be 30-50% bigge= r but that difference is zeroed out when you have both protocol encodings i= n place. "Executive Level" description: https://cyberphone.github.io/doc/research/se= ssion-based-remote-attestation.pdf Certainly a good point but I fear that it is not really design a secure sys= tem when the protocol does not terminate the secure world.

Every step of the protocol is supposed to be secured through MAC signatures. If the protocol doesn't obey the API (which is running in the secure world [*]), the session terminates and the accumulated operations are rolled back. Verifying my claims regarding the security of this scheme is non-trivial but it is not entirely different to TLS which you are an expert on.

It for example means that you can aggregate API calls protocol-wise. In my particular case it also enables the provisioning proxy running in the REE to perform some additional tasks but that probably does not apply to TEEP scenarios. > I believe the NONCE, the OCSP_DATA, the TOKEN, the REQUEST and the CIPHER_SUIT need to be made available to the OTrP Agent running inside the secure world to make some meaningful decisions. Most likely TOKEN, CIPHER_SUITE, NONCE and VERSION would not be needed because they are already better dealt with during session creation. > This data has to be encoded somehow. Right, all data needs to be encoded but the API would only bother about a single encoding which I believe would be binary and CBOR-encoded blobs in most cases. MACs only operate on the raw API data. > In that list the only item that is missing is the TYPE and it would have to be mapped into an API to make sense. Yes, TYPE is the API method. > The issue is: there is not much of a protocol left in the current design that can be terminated outside the secure world without making the computations in the secure world meaningless. Well, the intent at least is not terminating any secure operation outside the secure world. Anyway, a transformation of a static scheme into a session-based ditto certainly isn't something you can do in one day since it might spill back on the architecture as well. I leave it there, but anybody is free pinging me anytime on this topic. Session-based provisioning rocks!

Subject: Comment on JSON support in TEEP OTrPv2 draft

 

The OTrPv= 2 draft says it supports JSON and CBOR (which is great to see),
although in the meeting you correctly noted the JSON support isn’t co= mpletely

specified.  The CDD= L RFC (RFC 8610) does apply to JSON, as Appendix A explains,

as long as you only use = the specific subset of CDDL specified there.

 =

The current OTrPv2 draft= does not, however, currently stick to that subset of CDDL.

For example, it uses = 220;bstr” which Appendix A explains is not in that subset.=

I think OTrPv2 can still= be mapped to JSON, as long as you explain how

to map such types in the= OTrPv2 JSON format.   (I am assuming we do NOT need

the ability for an inter= mediary to translate between CBOR and JSON, in which case=

you’d need more th= an what I’m suggesting here.)

 = 

RFC 7493 was pointed out in the INTAREA WG, which species=
 “a restricted profile of JSON

designed to = maximize interoperability and increase confidence that

software can= process it successfully with predictable results”.  That is, it specifies

a profile of JSON, sort of like ho= w RFC 8610 specifies a profile of CDDL.  Section 4 of

RFC 7493 in particular gives recom= mendations for how to map specific data types,

including binary data.<= /span>

 

So I would suggest that the OTrPv2= doc talk about how to encode “bstr” (and any other<= /span>

CDDL types missing from the profil= e in RFC 8610 Appendix A) into types within the CDDL

JSON profile, and reference releva= nt sections of RFC 7493, at least informatively if not normatively,

for how/why.   E.g., RFC= 7493 section 4.4 can be used as the rule to encode bstr into

a string.

Thanks, Dave. I will look at th= e ways to best encode bstr.

 

The biggest problem I had was w= ith referencing CDDL items that refer to the JOSE counterparts to this stru= cture:

 

   Msg_AuthEnc_Wrappe= r =3D [ * (COSE_Mac_Tagged /

     &= nbsp;           &nbs= p;            COSE_S= ign_Tagged /

     &= nbsp;           &nbs= p;            COSE_M= ac0_Tagged /

     &= nbsp;            &nb= sp;           COSE_S= ign1_Tagged)]

 

Do you have an idea on how to s= olve that problem? I am not entirely sure there is even a CDDL description = of JOSE.

The OTrPv2 draft says it= supports JSON and CBOR (which is great to see),
although in the meeting you correctly noted the JSON support isn’t co= mpletely

specified= .  The CDDL RFC (RFC 8610) does apply to JSON, as Appendix A explains,=

as long a= s you only use the specific subset of CDDL specified there.

&nbs= p;

The curre= nt OTrPv2 draft does not, however, currently stick to that subset of CDDL.<= o:p>

For examp= le, it uses “bstr” which Appendix A explains is not in that sub= set.

I think O= TrPv2 can still be mapped to JSON, as long as you explain how

to map su= ch types in the OTrPv2 JSON format.   (I am assuming we do NOT ne= ed

the abili= ty for an intermediary to translate between CBOR and JSON, in which case

software can= process it successfully with predictable results”.  That is, it specifies

a profile of JSON, sort of like ho= w RFC 8610 specifies a profile of CDDL.  Section 4 of

JSON profile, and reference releva= nt sections of RFC 7493, at least informatively if not normatively,

for how/why.   E.g., RFC= 7493 section 4.4 can be used as the rule to encode bstr into
