Ciao Hannes Von: COSE <[email protected]> Im Auftrag von Aritra Banerjee (Nokia) Gesendet: Freitag, 14. Juli 2023 12:59 An: [email protected] Betreff: Re: [COSE] Definitions for Hybrid (PQ and classical) encryption Hello Ilari, Thank you for the comments, we will address all the comments raised. Hello Orlando, Thank you for sending over the document. Please refer to this draft we published (that Ilari mentioned) little over a week ago in the COSE working group: draft-ra-cose-hybrid-encrypt-00 - Hybrid key exchange in JOSE and COSE (ietf.org)<https://datatracker.ietf.org/doc/draft-ra-cose-hybrid-encrypt/> And feel free to contribute to the draft via the GitHub link: tireddy2/jose-hybrid-encrypt (github.com)<https://github.com/tireddy2/jose-hybrid-encrypt>. We would also be happy to collaborate with you on this topic. Thanks! Regards, Aritra.

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. datatracker.ietf.org
