Question: During EAP-AKA' authentication for 5G networks, what action is expected from the Mobile Equipment (ME) regarding the RAND and AUTN received in the EAP-request/AKA'-challenge?
Option 1: The ME generates a new set of RAND and AUTN to send back to the network.
Option 2: The ME forwards the RAND and AUTN to the USIM for processing within the EAP message IE.
Option 3: The ME stores the RAND and AUTN in its internal memory for future authentication sessions.
Option 4: The ME ignores the RAND and AUTN if service n°122 is not marked as 'available'.
Explanation: In EAP-AKA' authentication for 5G networks, the Mobile Equipment (ME) acts as an intermediary between the network and the UE's USIM. Upon receiving RAND and AUTN in an EAP-request/AKA'-challenge, the ME's primary role is to pass these parameters to the USIM for processing a response (RES), which the ME then returns to the network. This ensures secure UE authentication to the 5G network.
