Following up on the presentation <https://datatracker.ietf.org/meeting/123/materials/slides-123-jose-pq-kems-for-cose-and-jose-01> from last week I've opened two new issues in the draft's github tracker for topics we didn't discuss yet following the request for more feedback.
- "alg" values proposal <https://github.com/tireddy2/PQC_JOSE_COSE/issues/14>, fairly inconsequential but it does align the alg values with the rest of JOSE algs - Private JWK should be seed-only proposal <https://github.com/tireddy2/PQC_JOSE_COSE/issues/13>, this is to align ML-KEM private JWK format with what the outcome has been for ML-DSA private JWK format - to only use seeds As far as the other questions from the presentation to the working group go I believe this is fair summary - Input updates to the context in KDF - I believe we agreed on pulling the definition of AlgorithmID, concat(AlgorithmID, SuppPubInfo, SuppPrivInfo) into the main body of jose-pqc-kem instead of referencing parts of RFC7518's ECDH section. - Why not Use AKP Slide - Use of AKP doesn't introduce ambiguity, it removes it. Not being able to use the same JWK for both modes when using AKP is a problem that doesn't need solving. The WG poll on "Should OKP be used for ML-KEM JWKs" resulted in "Yes 0 / No 5 / No Opinion 7", on "Should we use AKP" was "Yes 5 / No 1 / No Opinion 10". Introducing a brand new key type was proposed but that only solves the optics problem of using OKP (i.e. having crv and x), I believe the next version should revert back to using AKP since the change to use of OKP was not grounded in any form of consensus on the mailing list prior to the meeting). Thank you for pushing the draft forward with solid momentum.
