The IESG has received a request from the Remote ATtestation ProcedureS WG (rats) to consider the following document: - 'RATS Conceptual Messages Wrapper (CMW)' <draft-ietf-rats-msg-wrap-18.txt> as Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the [email protected] mailing lists by 2025-10-13. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The Conceptual Messages introduced by the RATS Architecture (RFC9334) are protocol-agnostic data units that are conveyed between RATS roles during remote attestation procedures. Conceptual Messages describe the meaning and function of such data units within RATS data flows without specifying a wire format, encoding, transport mechanism, or processing details. The initial set of Conceptual Messages is defined in Section 8 of RFC9334 and includes Evidence, Attestation Results, Endorsements, Reference Values, and Appraisal Policies. This document introduces the Conceptual Message Wrapper (CMW) that provides a common structure to encapsulate these messages. It defines a dedicated CBOR tag, corresponding JSON Web Token (JWT) and CBOR Web Token (CWT) claims, and an X.509 extension. This allows CMWs to be used in CBOR-based protocols, web APIs using JWTs and CWTs, and PKIX artifacts like X.509 certificates. Additionally, the draft defines a media type and a CoAP content format to transport CMWs over protocols like HTTP, MIME, and CoAP. The goal is to improve the interoperability and flexibility of remote attestation protocols. By introducing a shared message format like the CMW, we can consistently support different attestation message types, evolve message serialization formats without breaking compatibility, and avoid having to redefine how messages are handled in each protocol. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-rats-msg-wrap/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ IETF-Announce mailing list -- [email protected] To unsubscribe send an email to [email protected]
