Abstract

This document specifies a method of the Authentication and Authorization for Constrained Environments (ACE) framework, which allows an Authorization Server to notify Clients and Resource Servers (i.e., registered devices) about revoked Access Tokens. The method relies on resource observation for the Constrained Application Protocol (CoAP), with Clients and Resource Servers observing a Token Revocation List on the Authorization Server. Resulting unsolicited notifications of revoked Access Tokens complement alternative approaches such as token introspection, while not requiring additional endpoints on Clients and Resource Servers.
