Question: In a 5G network, what is a key requirement for security signaling when transmitting identical data to multiple User Equipment (UEs), e.g., in service provisioning for numerous sensors?
Option 1: Maximizing encryption complexity to ensure ultra-security
Option 2: Minimizing security signaling overhead without compromising overall security
Option 3: Implementing a unique security protocol for each UE
Option 4: Disabling security for broadcast data to reduce overhead
Explanation: This option aligns with the principle of balancing efficiency with security. In scenarios where the same data is transmitted to multiple UEs, minimizing signaling overhead is crucial for network resource optimization without sacrificing the integrity and confidentiality ensured by the security level of the system. This approach supports efficient network operation while maintaining robust security standards.
