The resulting certificates are called C509 Certificates. The CBOR encoding supports a large subset of RFC 5280 and significantly reduces the size of certificates compatible with e.g. RFC 7925, IEEE 802.1AR (DevID), CNSA, and CA/Browser Forum Baseline Requirements. When used to re-encode DER encoded X.509 certificates, the CBOR encoding can in many cases reduce the size of RFC 7925 profiled certificates with over 50\%. The CBOR encoded structure can alternatively be signed directly ("natively signed"), which does not require re-encoding for the signature to be verified. The document also specifies COSE headers as well as a TLS certificate type for C509 certificates. NOTE: "C509" is a placeholder, name to be decided by the COSE WG.}, }
