Hi Roman, From: Lake <lake-bounces@ietf.org> on behalf of Roman Danyliw via Datatracker <noreply@ietf.org> Date: Wednesday, 26 April 2023 at 22:13 To: The IESG <iesg@ietf.org> Cc: lake-chairs@ietf.org <lake-chairs@ietf.org>, lake@ietf.org <lake@ietf.org> Subject: [Lake] Roman Danyliw's No Objection on charter-ietf-lake-01-00: (with COMMENT) Roman Danyliw has entered the following ballot position for charter-ietf-lake-01-00: No Objection When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/charter-ietf-lake/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- > Remote attestation of EDHOC peers, for instance using the available work from the RATS work group Unbounded, this could be a large body of work. Can the WG commit now to reuse the RATS work? or at least commit to adopting someone else's attestation framework. It would be helpful to constrain this work in some way. Remote attestation integrated in the handshake has been discussed in LAKE for years but only ended up being mentioned since edhoc-14 waiting the protocol to complete. The discussion I’m aware of was based on the reuse of existing IETF work specifically EAT/RATS, so that has always been the mindset. There is now work based on TLS which has progressed more rapidly that acknowledges other formats for encoding evidence besides EAT [1] and which extends the current RATS architecture [2]. The work in LAKE should reuse as much as possible existing work from RATS and TLS but with an additional eye on making the solution very lightweight. There should not be room for defining a new attestation framework, but I think similar extensions as mentioned above should be in scope, if necessary. Is this better: OLD Remote attestation of EDHOC peers, for instance using the available work from the RATS working group. NEW Remote attestation of EDHOC peers, reusing as much as possible available work from the RATS and TLS working groups. ? Göran [1] draft-fossati-tls-attestation [2] draft-bft-rats-kat
