full_form: Edge Enabler Client
context: The procedure flow of the solution is depicted in figure 6.13.2-1 and the steps are explained below. The solution assumes that there is a mechanism in the UE to authenticate the EEC. Figure 6.13.2-1: Authentication of EEC and UE by ECS/EES Step 0. UE and HPLMN run primary authentication and derive KAKMA. UE learns the A-KID and KAKMA. Step 1. KAF is derived as defined in AKMA procedure. KEEC is derived from KAF and EEC-ID as KEEC = KDF(KAF, EEC-ID). KEEC and E(KAF, EEC-ID) are revealed to the EEC where E(KAF, EEC-ID) is the encryption of EEC-ID under the key KAF. The EEC ID is authenticated in the UE with a method out of the scope of this solution, e.g. by the operating system running in the UE. Since the KEEC derived from the EEC ID is revealed only to the authenticated EEC having the EEC ID, the EES/ECS will ensure that the EEC is the client having the EEC ID after driving the KEEC from the EEC ID. If the EEC ID is sent over a secure channel between EEC and EES/ECS, then no
description: The Edge Enabler Client (EEC) is a network function that plays a crucial role in authenticating and establishing secure connections with the UE. It interacts with the UE and the ECS/EES to derive keys, authenticate identities, and ensure secure communication.
explanation: Based on its functions of authentication, key derivation, and encryption for secure communication between the UE and the network, the EEC fits the definition of a Network Function.
