COSE WG, This version of the draft updates explanatory text based on earlier feedback and adjusts the algorithms being registered. The registrations use 96 and 128 bit tags with a justification referencing both John M's analysis paper and IPsec CMAC use suggested by Russ. I believe that with these changes the draft is ready for an adoption call.

Name: draft-sipos-cose-cmac Revision: 02 Title: AES-CMAC for COSE Date: 2026-04-09 Group: Individual Submission Pages: 8 URL: https://www.ietf.org/archive/id/draft-sipos-cose-cmac-02.txt Status: https://datatracker.ietf.org/doc/draft-sipos-cose-cmac/ HTML: https://www.ietf.org/archive/id/draft-sipos-cose-cmac-02.html HTMLized: https://datatracker.ietf.org/doc/html/draft-sipos-cose-cmac Diff: https://author-tools.ietf.org/iddiff?url2=draft-sipos-cose-cmac-02 Abstract: The CBOR Object Signing and Encryption (COSE) specification defines structures for generating, conveying, and verifying Message Authentication Code (MAC) tags. This document registers code points for using the Advanced Encryption Standard (AES) block cipher in Cipher-based Message Authentication Code (CMAC) mode within those COSE structures. Specifically, these uses are for computing MAC tag values with no additional parameters. The IETF Secretariat
