Hi Mohamed, thank you for the review. Your comments will be addressed in the next document version, except the parameter name comments. Thie document is a profile of RFC 9629 for Composite ML-KEM, so we are using the RFC 9629 function and parameter naming terminology. The next version of the draft will add text with mapping between the RFC 9629 and Composite KEM terminology. My other email [1] shows the state of the terminology across multiple RFCs and drafts, unfortunately the nice table I made is not showing up in the plaintext rendering in the link. Thanks, Daniel [1] https://mailarchive.ietf.org/arch/msg/spasm/kYYsg_xpMenl-7wDH3VYtDmQ5Ik/ ________________________________ From: Mohamed Boucadair via Datatracker <noreply@ietf.org> Sent: 10 September 2026 5:40 AM To: The IESG <iesg@ietf.org> Cc: draft-ietf-lamps-cms-composite-kem@ietf.org <draft-ietf-lamps-cms-composite-kem@ietf.org>; housley@vigilsec.com <housley@vigilsec.com>; lamps-chairs@ietf.org <lamps-chairs@ietf.org>; spasm@ietf.org <spasm@ietf.org> Subject: Mohamed Boucadair's No Objection on draft-ietf-lamps-cms-composite-kem-01: (with COMMENT) Mohamed Boucadair has entered the following ballot position for draft-ietf-lamps-cms-composite-kem-01: No Objection When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines.

FYI, I wanted to use the following for my review, but it seems this is not the correct link: CURRENT: Source for this draft and an issue tracker can be found at https://github.com/lamps-wg/draft-composite-kem. Please find below some few comments: # Add a reference to indicate where this is standardized CURRENT: It was standardized with three parameter sets: ML-KEM-512, ML-KEM-768, and ML-KEM-1024. # Same notations Section 1.3 uses parameter names that are different from the ones in I-D.ietf-lamps-pq-composite-kem. Nothing wrong here, but using the same names would ease the mapping between the two specs. # minimum desired security level CURRENT: When Composite ML-KEM is employed in the CMS, the underlying components used within the KEMRecipientInfo structure SHOULD be consistent with a minimum desired security level. At first read, I found the above (especially the “minimum desired security level” part) not concrete enough. Seems some qualification is needed. I see that same text is also present in RFC9936, though. # Cite where the module is defined: OLD: IANA is requested to allocate a value from the "SMI Security for S/ MIME Module Identifier (1.2.840.113549.1.9.16.0)" registry for the included ASN.1 module NEW: IANA is requested to allocate a value from the "SMI Security for S/ MIME Module Identifier (1.2.840.113549.1.9.16.0)" registry for the ASN.1 module in Appendix A.
