Would that be sufficient? Section 3.7. of rfc9528 seems to use (modified) COSE_Key structure. And that requires codepoints for the keys. (The construction only being defined for EC2 and OKP is unlikely to become a problem, as any modern KEM design should be using OKP. This holds for ML-KEM and the CFRG hybrids.) FIPS 203 does not register the codepoints, and I am not aware of any draft seeking to do so. Furthermore, there seems to be opposition for it. AKP keys are not suitable for EDHOC, because EDHOC does not use COSE algorithms. -Ilari _______________________________________________ jose mailing list -- [email protected] To unsubscribe send an email to [email protected]
