Ballot Text

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.
