Ballot Text

Technical Summary

   This document describes JSON Object Signing and Encryption (JOSE) and
   CBOR Object Signing and Encryption (COSE) serializations for Module-
   Lattice-Based Digital Signature Standard (ML-DSA), a Post-Quantum
   Cryptography (PQC) digital signature scheme defined in FIPS 204.

Working Group Summary

   Extended discussions took place on the mailing list concerning the appropriate
   “kty” value to define and use for ML-DSA. The solution of introducing the new
   Algorithm Key Pair (AKP) type seemed to gather working group support.
   Additionally, comments were made about the specification of the “context”
   string in ML-DSA, as well as the draft being too underspecified. The authors
   addressed these comments during the WGLC.

   Ultimately, none of the document updates encountered significant objections. No
   one spoke against the adoption of the document during the WGLC. Consequently,
   there was no particular controversy over specific points, nor were there
   significant difficulties in reaching consensus.

Document Quality

   There are no known existing implementations yet, but the examples in
   Appendix A were generated using code specifically written for the draft,
   as reported on the COSE mailing list
   (https://mailarchive.ietf.org/arch/msg/cose/_IbCQoSJeXFG-GDZFlJZnZHCP1U/).


Personnel

   The Document Shepherd for this document is Lucas Prabel. The Responsible
