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…
Hypothesis Testing Approach to Detecting Collusion in Competitive Environments
Pedro Hespanhol, Anil Aswani
There is growing concern about tacit collusion using algorithmic pricing, and regulators need tools to help detect the possibility of such collusion. This paper studies how to desi…
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…
Optimization Hierarchy for Fair Statistical Decision Problems
Anil Aswani, Matt Olfat
Data-driven decision-making has drawn scrutiny from policy makers due to fears of potential discrimination, and a growing literature has begun to develop fair statistical technique…
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…
