Hi all, We have just published version -01 of the PQ/T Hybrid Composite Signatures WG Document: https://datatracker.ietf.org/doc/draft-ietf-jose-pq-composite-sigs/01.
In particular: - We have expanded the Security Considerations section with considerations for key reuse, integrity of the composite public key, and the specific lack of SUF-CMA security against quantum adversaries which was highlighted during the previous call for adoption of the draft; - Test vectors for JOSE/COSE for all 6 combinations MLDSA + ECDSA / EdDSA; - General improvements for better readability. We would appreciate any feedback from the group, particularly regarding the Security Considerations section. You can also track progress or open issues on our GitHub repository: https://github.com/ietf-wg-jose/draft-ietf-jose-pq-composite-sigs Best, Lucas -----Original Message----- From: [email protected] <[email protected]> Sent: 27 February 2026 16:06 To: [email protected] Cc: [email protected] Subject: [jose] I-D Action: draft-ietf-jose-pq-composite-sigs-01.txt Internet-Draft draft-ietf-jose-pq-composite-sigs-01.txt is now available. It is a work item of the Javascript Object Signing and Encryption (JOSE) WG of the IETF. Title: PQ/T Hybrid Composite Signatures for JOSE and COSE Authors: Lucas Prabel Sun Shuzhou John Gray Tirumaleswar Reddy Name: draft-ietf-jose-pq-composite-sigs-01.txt Pages: 29 Dates: 2026-02-27 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 either ECDSA or EdDSA as the traditional component.
