Hello all, We have published a new version of https://datatracker.ietf.org/doc/draft-prabel-jose-pq-composite-sigs/01/ which describes how to use PQ/T composite keys and signatures for JOSE and COSE. We are pleased to welcome John Gray as a co-author of the draft, who will in particular help us align with the LAMPS composite draft when necessary.
The draft was presented at IETF 121, and numerous changes have been made since. In particular: - as with draft-ietf-cose-dilithium-07, we now only support the seed representation for the private key; - we changed the composite signature combiner to align with the upcoming version of the LAMPS composite draft; - test vectors for JOSE have been added. We welcome all comments, feedback and suggestions, and we plan to present the updated draft at IETF 123 in Madrid.

Name: draft-prabel-jose-pq-composite-sigs Revision: 01 Title: PQ/T Hybrid Composite Signatures for JOSE and COSE Date: 2025-06-16 Group: Individual Submission Pages: 24 URL: https://www.ietf.org/archive/id/draft-prabel-jose-pq-composite-sigs-01.txt Status: https://datatracker.ietf.org/doc/draft-prabel-jose-pq-composite-sigs/ HTML: https://www.ietf.org/archive/id/draft-prabel-jose-pq-composite-sigs-01.html HTMLized: https://datatracker.ietf.org/doc/html/draft-prabel-jose-pq-composite-sigs Diff: https://author-tools.ietf.org/iddiff?url2=draft-prabel-jose-pq-composite-sigs-01 Abstract: This document describes JSON Object Signing and Encryption (JOSE) and CBOR Object Signing and Encryption (COSE) serializations for PQ/T hybrid composite signatures. The composite algorithms described combine ML-DSA as the post-quantum component and ECDSA as the traditional component.
