ACE Working Group L. Seitz Internet-Draft Combitech Intended status: Standards Track April 29, 2020 Expires: October 31, 2020 Additional OAuth Parameters for Authorization in Constrained Environments (ACE) draft-ietf-ace-oauth-params-13 Abstract This specification defines new parameters and encodings for the OAuth 2.0 token and introspection endpoints when used with the framework for authentication and authorization for constrained environments (ACE). These are used to express the proof-of-possession key the client wishes to use, the proof-of-possession key that the Authorization Server has selected, and the key the Resource Server uses to authenticate to the client.

Introduction The Authentication and Authorization for Constrained Environments (ACE) specification [I-D.ietf-ace-oauth-authz] requires some new parameters for interactions with the OAuth 2.0 [RFC6749] token and introspection endpoints, as well as some new claims to be used in access tokens. These parameters and claims can also be used in other contexts and have therefore been put into a dedicated document, to facilitate their use in a manner independent of [I-D.ietf-ace-oauth-authz]. Note that although all examples are shown in Concise Binary Object Respresentation (CBOR) [RFC7049], JSON [RFC8259] MAY be used as an alternative for HTTP-based communications, as specified in [I-D.ietf-ace-oauth-authz].
