Additional OAuth Parameters for Authorization in Constrained
Environments (ACE)
draft-ietf-ace-oauth-params-14
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.

1. 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
Representation (CBOR) [RFC8949], JSON [RFC8259] MAY be used as an
alternative for HTTP-based communications, as specified in
[I-D.ietf-ace-oauth-authz].
