Abstract

   JSON Web Message (JWM) is a flexible way to encode application-level
   messages in JSON for transfer over a variety of transport protocols.
   JWMs use JSON Web Encryption (JWE) to protect integrity, achieve
   confidentiality, and achieve repudiable authentication; alternatively
   or in addition, they use JSON Web Signatures (JWS) to associate
   messages with a non-repudiable digital signature.
