Abstract

This project will study the issue of physical layer security in cyber-physical systems (CPS). CPS integrate physical components, such as plants, sensors, and actuators, with cyber components over wireless networks, providing autonomy, reliability, and efficiency. Before the large-scale deployment of such systems in safety-critical applications, it is essential to ensure their safety against adversarial attacks. Attacks on physical components, including sensors, actuators, and the network, may not be adequately protected by existing cybersecurity measures. The current project aims to supplement these cybersecurity measures through a control-theoretic approach. We will specifically investigate the quickest detection of adversarial attacks on the physical components of networked control systems (NCS), which are a very popular type of CPS. Additionally, we will address the resilient state estimation problem when the system is under attack. To support our study, we will simulate plant models, the attacker system, and the detection and estimation mechanisms primarily in MATLAB, allowing us to test and validate our theories and methods.
