John, I'm not deeply familiar with EDHOC use cases but am looking at COSE along with some form of labeled public key transport. Right now, that is a combination of in-message x5chain/x5t/kid with out-of-message COSE_Key objects; similar, I think, to what is proposed for EDHOC.
When discussing using CWT as a public key transport, do you mean to use a bare CWT Claim Map with a "cnf" key, or a full CWT sign/MAC structure attested to by some issuing entity? Is it proposed to replace the raw COSE_Key use with a CWT entirely, or add CWT as an alternative? Thanks for clarifying to an outside perspective. Brian S.
