Hello all,
The JOSE draft "PQ/T Hybrid Composite Signatures for JOSE and COSE" has been updated to v4 (https://datatracker.ietf.org/doc/draft-prabel-jose-pq-composite-sigs/04/). We now welcome T. Reddy as a co-author, and the following changes were made: 1. We included 3 new composite algorithms for JOSE & COSE, to support EdDSA. The new registered composites aligned with the algorithms registered in the LAMPS composite draft. 2. We performed some editorial modifications to improve clarity and readability. We welcome all comments, feedback and suggestions, and you can also submit issues on our Github repository: https://github.com/lucasprabel/draft-jose-pq-composite-sigs Best, Lucas -----Original Message----- From: [email protected] <[email protected]> Sent: Friday, August 22, 2025 3:18 PM To: Tirumaleswar Reddy.K <[email protected]>; John Gray <[email protected]>; Lucas Prabel <[email protected]>; Sun Shuzhou <[email protected]>; Tirumaleswar Reddy <[email protected]> Subject: New Version Notification for draft-prabel-jose-pq-composite-sigs-04.txt A new version of Internet-Draft draft-prabel-jose-pq-composite-sigs-04.txt has been successfully submitted by Lucas Prabel and posted to the IETF repository. Name: draft-prabel-jose-pq-composite-sigs Revision: 04 Title: PQ/T Hybrid Composite Signatures for JOSE and COSE Date: 2025-08-22 Group: Individual Submission Pages: 22 URL: https://www.ietf.org/archive/id/draft-prabel-jose-pq-composite-sigs-04.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-04.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-04 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. The IETF Secretariat
