Tschofenig ARM Limited December 13, 2015 Proof-of-Possession Key Semantics for JSON Web Tokens (JWTs) draft-ietf-oauth-proof-of-possession-09 Abstract This specification defines how to express a declaration in a JSON Web Token (JWT) that the presenter of the JWT possesses a particular key and that the recipient can cryptographically confirm proof-of- possession of the key by the presenter. Being able to prove possession of a key is also sometimes described as the presenter being a holder-of-key.
