Question: What is the purpose of the EAP message reliable transport procedure in the context of 5G System (5GS) Non-Access Stratum (NAS) protocol?
Option 1: To provide a secure tunnel for user data transmission between the UE and the network.
Option 2: To ensure reliable transport of EAP-request and EAP-response messages, ngKSI, and ABBA between the network and the UE.
Option 3: To authenticate the UE using a challenge-response mechanism.
Option 4: To establish an IPsec tunnel for secure communication between the UE and the network.
Explanation: The EAP message reliable transport procedure is designed to provide a reliable means of transporting EAP-request and EAP-response messages, ngKSI, and ABBA between the network (AMF) and the UE. This ensures that these critical authentication-related messages are delivered correctly and reliably, which is essential for secure authentication in 5G networks.
