Abstract
A computer system and computer implemented method of detecting attacks on physical systems are disclosed. The system may include one or more databases and one or more controller configured to execute instructions. The instructions may include the following method steps: receiving at least one signal related to a monitored physical system; de-noising the at least one signal to extract a smooth portion of the signal; detecting one or more states of the monitored physical system by analyzing the smooth portion of the signal; obtaining a noise portion of the signal by subtracting the de-noised smooth portion from the at least one signal; classifying the noise portion; determining expected states of the system based on the classified noise portion; comparing the expected states to the detected one or more states; and detecting an attack on the monitored physical system based on the comparison.
