With the CBOR Web Token (CWT) specification nearing completion, which provides the CBOR equivalent of JWTs, I thought that it was also time to introduce the CBOR equivalent of RFC 7800, “Proof-of-Possession Key Semantics for JSON Web Tokens (JWTs)”, so that applications using CWTs will have a standard representation for proof-of-possession keys. I know that PoP keys are important to ACE applications, for instance. I therefore took RFC 7800 and produced the CBOR/CWT equivalent of it.
The specification is available at:
