Hi all, The new draft https://datatracker.ietf.org/doc/draft-ra-cose-hybrid-encrypt/ defines the use of traditional and PQC algorithms, a hybrid post-quantum KEM, for JOSE and COSE. Hybrid key exchange refers to using multiple key exchange algorithms simultaneously and combining the result with the goal of providing security even if all but one of the component algorithms is broken.
Comments and suggestions are welcome.

Name: draft-ra-cose-hybrid-encrypt Revision: 00 Title: Hybrid key exchange in JOSE and COSE Document date: 2023-07-05 Group: Individual Submission Pages: 30 URL: https://www.ietf.org/archive/id/draft-ra-cose-hybrid-encrypt-00.txt Status: https://datatracker.ietf.org/doc/draft-ra-cose-hybrid-encrypt/ Html: https://www.ietf.org/archive/id/draft-ra-cose-hybrid-encrypt-00.html Htmlized: https://datatracker.ietf.org/doc/html/draft-ra-cose-hybrid-encrypt Abstract: Hybrid key exchange refers to using multiple key exchange algorithms simultaneously and combining the result with the goal of providing security even if all but one of the component algorithms is broken. It is motivated by transition to post-quantum cryptography. This document provides a construction for hybrid key exchange in JOSE and COSE. It defines the use of traditional and PQC algorithms, a hybrid post-quantum KEM, for JOSE and COSE. The IETF Secretariat
