Technical Summary CBOR Web Token (CWT) is a compact means of representing claims to be transferred between two parties. The claims in a CWT are encoded in the Concise Binary Object Representation (CBOR) and CBOR Object Signing and Encryption (COSE) is used for added application layer security protection. A claim is a piece of information asserted about a subject and is represented as a name/value pair consisting of a claim name and a claim value. CWT is derived from JSON Web Token (JWT) but uses CBOR rather than JSON. Working Group Summary The document was not controversial, and received a great deal of review from many participants. A first WGLC revealed a few issues that required enough changes that a second WGLC was made. The second WGLC attracted fewer comments, but the document is largely unchanged from the first WGLC, and we believe it to be in good shape.
