Hello all, I just updated the JOSE draft "PQ/T Hybrid Composite Signatures for JOSE and COSE" to v02 (https://datatracker.ietf.org/doc/draft-prabel-jose-pq-composite-sigs/02/).
The motivation of this update was: - to align with the v06 update of draft-ietf-lamps-pq-composite-sigs-06, which removed the randomizer from the pre-hash; - to answer Ilari Liusvaara's previous comments on our draft (https://mailarchive.ietf.org/arch/msg/jose/zoTHYqXkfe3wVPrTIp2wzoYAV7I/). In particular, I made the following changes: 1. Align with the LAMPS Composite v06 draft by removing the randomizer from the pre-hash computation; 2. Now use the same domain separators as the LAMPS draft, defined as the DER encoding of the algorithms OIDs (rather than defining them as the octets of the ASCII representation of the composite algo); 3. Modified the key type used in the draft from AKP-EC(2) to simply AKP, as done in the COSE ML-DSA draft. This was achieved by using the serialization subroutines from draft-ietf-lamps-pq-composite-sigs-06; 4. Updated the JOSE test vectors accordingly.
