Abstract
Systems and methods for detecting compromised sensors using dynamic watermarking. In some examples, a method includes injecting a dynamic random signal into an input of a power distribution system. The power distribution system includes at least one sensor and at least one power electronic controller configured to use the at least one sensor. The method includes monitoring a sensor signal from the at least one sensor. The method includes determining whether the at least one sensor is compromised based on a comparison between the dynamic random signal and the sensor signal.
