Question: In a Generic Bootstrapping Architecture (GBA) setup, what is a key requirement for a server implementing the bootstrapping function, from the perspective of the home operator?
Option 1: Only to be trusted for handling subscriber data
Option 2: To be trusted specifically for handling authentication vectors
Option 3: Not to be trusted for any security-related operations
Option 4: To solely manage network application functions in visited networks
Explanation: This is correct because, according to the principles outlined for bootstrapping procedures in GBA, the server implementing the bootstrapping function needs to be trusted by the home operator specifically for handling authentication vectors. This ensures a secure environment for managing sensitive authentication information.
