    abstract =  {This specification defines an application profile for authentication and authorization for Publishers and Subscribers in a constrained pub-sub scenario, using the ACE framework. This profile relies on transport layer or application layer security to authorize the pub- sub clients to the broker. Moreover, it describes the use of application layer security to protect the content of the pub-sub client message exchange through the broker. The profile covers pub- sub scenarios using either the Constrained Application Protocol (CoAP) {[}I-D.ietf-core-coap-pubsub{]} or the Message Queue Telemetry Transport (MQTT) {[}MQTT-OASIS-Standard-v5{]} protocol.},
