Title: “Security of Cyber-Physical Systems: Theory and Applications of the Dynamic Watermarking Method”
- How to protect our critical infrastructure from cyber-attacks?
- How to secure the power grid, oil refineries, autonomous vehicles?
- What sort of guarantees can be provided?
The coming decades will see the large scale deployment of networked cyber–physical systems to address global needs in energy, water, health care, transportation, etc. However, as recent events have shown, such systems are vulnerable to cyber attacks. We present a general purpose technique, called “dynamic watermarking,” for detecting malicious activity in networked systems of sensors and actuators. It provides a provable guarantee of detection of any non-zero power attack. This method has been implemented in several systems of interest. We present the results of attacks on an autonomous automobile, a grid-tied photovoltaic system, a process control system, and a tethered helicopter. We also present the results of simulation studies of attacks on larger scale systems such as the power grid, through attacks on its automatic gain control loop, and attacks on the Tennessee-Eastman model, an open source benchmark that has been developed for the purpose of evaluating process control technology used in industries such as chemical plants and oil refineries.
