Proof-of-Possession Key Semantics for JWTs spec addressing WGLC comments

OAuth logoThe editors have published draft-ietf-oauth-proof-of-possession-03, which addresses the working group last call comments received. Thanks to all of you who provided feedback. The changes were:

  • Separated the jwk and jwe confirmation members; the former represents a public key as a JWK and the latter represents a symmetric key as a JWE encrypted JWK.
  • Changed the title to indicate that a proof-of-possession key is being communicated.
  • Updated language that formerly assumed that the issuer was an OAuth 2.0 authorization server.
  • Described ways that applications can choose to identify the presenter, including use of the iss, sub, and azp claims.
  • Harmonized the registry language with that used in JWT [RFC 7519].
  • Addressed other issues identified during working group last call.
  • Referenced the JWT and JOSE RFCs.

The updated specification is available at:
