Covariance-Robust Dynamic Watermarking
Matt Olfat, Stephen Sloan, Pedro Hespanhol +3
Attack detection and mitigation strategies for cyberphysical systems (CPS) are an active area of research, and researchers have developed a variety of attack-detection tools such a…
Detecting Deception Attacks on Autonomous Vehicles via Linear Time-Varying Dynamic Watermarking
Matthew Porter, Sidhartha Dey, Arnav Joshi +4
Cyber-physical systems (CPS) such as autonomous vehicles rely on both on-board sensors and external communications to estimate their state. Unfortunately, these communications rend…
Detecting Generalized Replay Attacks via Time-Varying Dynamic Watermarking
Matthew Porter, Pedro Hespanhol, Anil Aswani +2
Cyber-physical systems (CPS) often rely on external communication for supervisory control or sensing. Unfortunately, these communications render the system vulnerable to cyber-atta…
Sensor Switching Control Under Attacks Detectable by Finite Sample Dynamic Watermarking Tests
Pedro Hespanhol, Matthew Porter, Ram Vasudevan +1
Control system security is enhanced by the ability to detect malicious attacks on sensor measurements. Dynamic watermarking can detect such attacks on linear time-invariant (LTI) s…
