Cyber Physical Attack Detection (CPAD)

The invention relates to anomaly detection and more specifically to cyber physical attack detection (CPAD). CPAD infers underlying physical relationships between components by analyzing the sensor measurements of a system. It then uses these measurements to detect signs of a non-physically realizable state, which is indicative of an integrity attack on the system. CPAD can be used on any highly-instrumented cyber-physical system to detect integrity attacks and identify the component or components compromised. It has applications to power distribution grids, nuclear and industrial plants, and complex vehicles.
