Hello Ilari, Thanks for your quick feedback. About the Ascon application in COSE, the initial version of the draft implies the usage of Ascon AEAD only for the Content Encryption but not for the Key Wrap. Thus, only one algorithm type was requested to be registered. About the "nonce" parameter, I was a bit confused how it is used because I saw it is registered for both signing and encryption. So thanks for the clarification, I will modify that part.

The draft does not seem to say how the algorithm is used in COSE. I presume this is subject to RFC 9052 section 5.3. (AEAD) processing rules (so for bulk encryption and key wrap)? In JOSE, the nonce is meant to be placed into JWE Initialization Vector ("iv"). The "nonce" parameter is something else, meant to be used with signatures, not encryption (even if it is also defined for encryption). I do not offhand know any useful way to use "nonce" with most encryption algorithms. > ----- Mail transféré ----- > De: [email protected] > À: "Hélène LE BOUDER" <[email protected]>, "Alexander PELOV" > <[email protected]>, "dmytro ochkas" > <[email protected]>, "Hélène LE BOUDER" > <[email protected]> > Envoyé: Mercredi 8 Janvier 2025 12:08:29 > Objet: New Version Notification for draft-ochkas-cose-ascon-00.txt > > A new version of Internet-Draft draft-ochkas-cose-ascon-00.txt has been > successfully submitted by Dmytro Ochkas and posted to the > IETF repository. > > Name: draft-ochkas-cose-ascon > Revision: 00 > Title: Ascon-AEAD128 for JOSE and COSE > Date: 2025-01-08 > Group: Individual Submission > Pages: 9 > URL: https://www.ietf.org/archive/id/draft-ochkas-cose-ascon-00.txt > Status: https://datatracker.ietf.org/doc/draft-ochkas-cose-ascon/ > HTMLized: https://datatracker.ietf.org/doc/html/draft-ochkas-cose-ascon -Ilari _______________________________________________ COSE mailing list -- [email protected] To unsubscribe send an email to [email protected] _______________________________________________ COSE mailing list -- [email protected] To unsubscribe send an email to [email protected]
