Fraunhofer SIT Intel Linaro This document defines two encapsulation formats for RATS conceptual messages (i.e., evidence, attestation results, endorsements and reference values.) The first format uses a CBOR or JSON array with two mandatory members, one for the type, another for the value, and a third optional member complementing the type field that says which kind of conceptual message(s) are carried in the value. The other format wraps the value in a CBOR byte string and prepends a CBOR tag to convey the type information. This document also defines a corresponding CBOR tag, as well as JSON Web Tokens (JWT) and CBOR Web Tokens (CWT) claims. These allow embedding the wrapped conceptual messages into CBOR-based protocols and web APIs, respectively.
