DescriptionSensor attacks alter sensor readings and spoof the cyber-physical systems to perform dangerous actions. Existing detection works tend to minimize the detection delay and false alarms simultaneously, while we argue that attack detection should dynamically balance the two metrics when a physical system is at different states. Along with this argument, we propose an adaptive sensor attack detection system that can adapt the detection delay and false alarms at run time to meet a varying detection deadline and improve usability. Finally, we validate our detection system using multiple CPS simulators and a reduced-scale autonomous vehicle testbed.
