[saag] RATS @ IETF 113

RATS WG met March 22nd and 23rd.

* The “RIV” draft (draft-ietf-rats-tpm-based-network-device-attest) successfully passed IETF reviews and is pending assignment of an RFC number.

* The “CHARRA” draft (draft-ietf-rats-yang-tpm-charra) has completed most of the IETF reviews except has a few outstanding YANG doctor issues to clean up. It is expected to be clear of these soon and will be ready for RFC status.

* The device subscription draft (draft-ietf-rats-network-device-subscription) is nearing completion having updated the security considerations section. More socialization of that section is needed before moving to WGLC.

* The AR4SI draft (draft-ietf-rats-ar4si) has clarifying text for certain trustworthiness claims. There has been mailing list threads related to EAT ‘security-level’ and ‘swresults’ claims in EAT. The authors are awaiting additional meaningful market uptake before requesting WGLC.

* The RATS Architecture draft (draft-ietf-rats-architecture) has been submitted to IESG for publication. There are pending IESG reviews.

* The EAT draft (draft-ietf-rats-eat) requested and received pre-allocation code points added to the IANA registry (https://www.iana.org/assignments/cwt/cwt.xhtml#claims-registry). There were a number of editing and cleanup changes applied as well as the addition of 3 new claims and additional clarification in the privacy considerations section. A new issue was raised relating to apparent dependency on the UCCS draft (draft-ietf-rats-uccs) where use of EAT may require normative content found in the UCCS draft. This issue is being discussed on the RATS mailing list.

* The DAA (draft-ietf-rats-daa), UCCS and Reference Interaction Models (draft-ietf-rats-reference-interaction-models) drafts continue to make progress but not significantly closer to WGLC.

* Concise Reference Integrity Manifest (CoRIM) draft was discussed that defines a schema for capturing attestation reference values and endorsed values. The draft authors invite others to review and comment.

* The working group has proposed changing the charter to include aspects of the RATS Architecture that was not defined at the time of initial chartering - Endorsers and Reference Value Providers. The final decision to approve the new charter text will commence on the RATS mailing list.
