CYBER PHYSICAL ATTACKS DETECTION BASED ON GRAPH FOURIER TRANSFORM
A. A. Shtyrkina, E. B. Aleksandrova Peter the Great St. Petersburg Polytechnic University
Annotation: The paper is devoted to the topic of detecting cyber-physical systems (CPS) attacks that affect the parameters of the functioning of devices. The potential consequences of cyber attacks on the CPS, as well as the corresponding changes in the modeling graph, are considered. A method for detecting cyberattacks based on the graph Fourier transform and the gradient boosting algorithm is proposed. The method makes it possible to detect a non-standard change in the operation parameters of devices and evaluate its criticality from the point of view of the centrality of a group of modeling vertices.
Keywords: cyber-physical systems, graph theory, graph signal processing.
