This document describes JOSE and COSE serializations for ML-DSA, which was derived from Dilithium, a Post-Quantum Cryptography (PQC) based digital signature scheme.¶
This document does not define any new cryptography, only seralizations of existing cryptographic systems described in [FIPS-204].¶
Note to RFC Editor: This document should not proceed to AUTH48 until NIST completes paramater tuning and selection as a part of the PQC standardization process.¶
This note is to be removed before publishing as an RFC.¶

ML-DSA is derived from Version 3.1 of CRYSTALS-DILITHIUM, as noted in [FIPS-204].¶
CRYSTALS-DILITHIUM is one of the post quantum cryptography algorithms selected in [NIST-PQC-2022].¶
TODO: Add complete examples for ML-DSA-44, ML-DSA-65, ML-DSA-87.¶
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶
The ML-DSA Signature Scheme is paramaterized to support different security level.¶
