This document specifies a profile for the ACE (Authentication and Authorization for Constrained Environments) to enable authorization in an MQTT-based publish-subscribe messaging system. Proof-of- possession keys, bound to OAuth2.0 access tokens, are used to authenticate and authorize publisher and subscriber clients. The protocol relies on TLS for confidentiality and server authentication.
