coap_dtls Profile for delegating client Authentication and Authorization for Constrained Environments by establishing a Datagram Transport Layer Security (DTLS) or Transport Layer Security (TLS) channel between resource-constrained nodes. 1 [RFC9202][RFC9430]
coap_oscore Profile for using OSCORE to secure communication between constrained nodes using the Authentication and Authorization for Constrained Environments framework. 2 [RFC9203]
mqtt_tls Profile for delegating Client authentication and authorization using MQTT for the Client and Broker (RS) interactions and HTTP for the AS interactions. TLS is used for confidentiality and integrity protection and server authentication. Client authentication can be provided either via TLS or using in-band PoP validation at the MQTT application layer. 3 [RFC9431]
