1. A method, performed by a user equipment (UE) configured to communicate in a 5G network, of authentication and authorization between an edge enabler client (EEC) of the UE and an edge configuration server (ECS), the method comprising:
performing primary authentication with the 5G network to obtain a KAUSF;
generating a Kedge and a Kedge identifier (ID) using the KAUSF and a subscription permanent identifier (SUPI);
providing the Kedge and the Kedge ID to the EEC to cause it to compute a MACEEC using the Kedge and an EEC ID; and
sending to the ECS an application registration request, the application registration request including the EEC ID, the MACEEC, and the Kedge ID, in which the sending comprises either sending a non-access stratum (NAS) message or a user-plane message.
