Question: In a Generic Authentication Architecture (GAA) utilizing TLS Handshake Protocol, what determines the duration for which a negotiated session's Session ID remains valid?
Option 1: A standardized timer defined by 3GPP specifications
Option 2: Local policies of both the User Equipment (UE) and the Bootstrapping Server Function (BSF)
Option 3: The duration of the TLS Handshake Protocol negotiation process
Option 4: A default value set by the network operator
Explanation: In the context of GAA using TLS Handshake Protocol, the validity period of a Session ID, which identifies a negotiated session between the UE (User Equipment) and the BSF (Bootstrapping Server Function), is not rigidly set by external standards or network operator defaults. Instead, it is flexibly determined by the individual policies of both the UE and the BSF, allowing for adaptability based on specific security requirements or operational needs. This approach ensures that session management can be optimized according to the unique conditions of each endpoint.
