Question: In a Generic Bootstrapping Architecture (GBA) for 2G networks, what are the primary components involved in the bootstrapping procedure as specified in the GAA architecture?
Option 1: UE (User Equipment), BSF (Bootstrapping Server Function), and Application Server with no key material generation.
Option 2: Only UE (User Equipment) and BSF (Bootstrapping Server Function) for authentication.
Option 3: UE (User Equipment), Serving Network, and Application Server without explicit BSF interaction.
Option 4: UE (User Equipment), BSF (Bootstrapping Server Function), and a key material generation procedure.
Explanation: The correct answer involves all crucial elements of the 2G GBA bootstrapping procedure as outlined in the context. This includes the User Equipment (UE) which initiates the process, the Bootstrapping Server Function (BSF) that handles the authentication, and the key material generation procedure which is essential for securing subsequent communications between the UE and applications utilizing GBA. Option 4 accurately reflects the comprehensive nature of the bootstrapping procedure as specified.
