My research focuses on the security of Cyber-Physical Systems. In particular, we are looking at attack and defense in critical infrastructures like water, power, and other autonomous systems. Working on state-of-the-art ICS testbeds in cross-disciplinary domains of computer science and industrial control systems. Our work is centered around authenticating sensors, actuators, and other computationally constrained devices in cyber-physical systems by studying the cyber-physical features of the devices, much like a fingerprint.
