The IESG has received a request from the Limited Additional Mechanisms for PKIX and SMIME WG (lamps) to consider the following document: - 'Use of ML-KEM in the Cryptographic Message Syntax (CMS)' <draft-ietf-lamps-cms-kyber-10.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the last-call@ietf.org mailing lists by 2025-07-01. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Module-Lattice-Based Key-Encapsulation Mechanism (ML-KEM) is a quantum-resistant key-encapsulation mechanism (KEM). Three parameters sets for the ML-KEM algorithm are specified by NIST in FIPS 203. In order of increasing security strength (and decreasing performance), these parameter sets are ML-KEM-512, ML-KEM-768, and ML-KEM-1024. This document specifies the conventions for using ML- KEM with the Cryptographic Message Syntax (CMS) using the KEMRecipientInfo structure. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-lamps-cms-kyber/ No IPR declarations have been submitted directly on this I-D.
