[saag] COSE Report for IETF 124

COSE met on Tuesday 2025-11-04

The following drafts are nearly ready for WGLC:

- draft-ietf-cose-hpke -- needs a new revision and a second WGLC will be issued.

The following WG drafts were also discussed:

- draft-ietf-cose-{sphincs,falcon} - they were aligned with
draft-ietf-cose-dilithium prior to the meeting and the way ahead
depends on the NIST documents, but is generally clear.

- draft-ietf-cose-bls-key-representitions - it waits for other documents.

​

The following non-working group drafts were presented to the group:

- draft-lundberg-cose-two-party-signing-algs -- had a lively
discussion and people promised to review it and report back on the ML.
Based on feedback adoption call will probably be issued before next
meeting.

- draft-lemmons-cose-composite-claims -- had interest from the working
groups and people promised to review it and report back on the ML. If
sufficient feedback is provided an adoption call will soon follow.

- draft-lspm-cose-c509-test-vectors -- it was of interest for the WG.

- a draft idea presented by Carsten Bormann

The following WG drafts were not (meaningfully) discussed:

- draft-ietf-cose-cbor-encoded-cert - it waits for AD follow up

- draft-ietf-cose-hash-envelope, draft-ietf-cose-merkle-tree-proofs,
draft-ietf-cose-dilithium and

draft-ietf-cose-tsa-tst-header-parameterar are with the RFC editor and
there was nothing to discuss.

Best regards,

Ivo and Mike
