      Assertion Framework for OAuth 2.0 Client Authentication and
                          Authorization Grants
                     draft-ietf-oauth-assertions-18

Abstract

   This specification provides a framework for the use of assertions
   with OAuth 2.0 in the form of a new client authentication mechanism
   and a new authorization grant type.  Mechanisms are specified for
   transporting assertions during interactions with a token endpoint, as
   well as general processing rules.

   The intent of this specification is to provide a common framework for
   OAuth 2.0 to interwork with other identity systems using assertions,
   and to provide alternative client authentication mechanisms.

   Note that this specification only defines abstract message flows and
   processing rules.  In order to be implementable, companion
   specifications are necessary to provide the corresponding concrete
   instantiations.
