Skip to Secure: Securing Cyber-physical Control Loops with Intentionally Skipped Executions
The research proposes using intentional skipping of control loop executions as a control-theoretic defense against stealthy attacks that try to manipulate data integrity in cyber-physical systems. By synthesizing optimal skipping patterns based on performance and attack resilience, the method creates sporadic intrusion detection systems (IDS) that significantly lower the resource overhead of traditional security measures without sacrificing system safety or performance.
