Using encrypted control in safety-critical systems introduces both benefits and challenges. On the positive side, encrypted control can enhance data privacy and security, protecting sensitive information from unauthorized access and cyber threats. This is particularly crucial in safety-critical systems where the integrity of control data is paramount. However, there are implications related to the performance-security trade-offs inherent in encrypted control. The computational overhead of encryption and decryption processes can introduce delays in control actions, affecting the system's real-time responsiveness. Analyzing the security-performance trade-offs involves evaluating factors such as encryption/decryption speed, communication latency, and computational resources required for encrypted control. Balancing the security needs with the system's performance requirements is essential to ensure the safe and efficient operation of safety-critical systems.
