      Proof-of-Possession Key Semantics for JSON Web Tokens (JWTs)
                draft-ietf-oauth-proof-of-possession-06

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.

1.  Introduction

   This specification defines how a JSON Web Token (JWT) [JWT] can
   declare that the presenter of the JWT possesses a key and that the
   recipient can cryptographically confirm that the presenter possesses
   that key.  Proof-of-possession of a key is also sometimes described
   as the presenter being a holder-of-key.  The
   [I-D.ietf-oauth-pop-architecture] specification describes key
