We have created the initial working group version of the CBOR Web Token (CWT) specification based on draft-wahlstroem-ace-cbor-web-token-00, with no normative changes. The abstract of the specification is:
CBOR Web Token (CWT) is a compact means of representing claims to be transferred between two parties. CWT is a profile of the JSON Web Token (JWT) that is optimized for constrained devices. 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.
Changes requested during the call for adoption will be published in the -01 version but we first wanted to publish a clean -00 working group draft.
The specification is available at:
An HTML-formatted version is also available at:
