The sensor‐actuators stealthy cyber‐attacks framework on networked control systems: A data‐driven approach

Abstract

In this study, we address two fundamental questions that are crucial for designing stealthy cyber‐attacks similar to false data injection. The first question involves obtaining an accurate dynamic model of the target to ensure stealthy performance under a detector. The second question pertains to understanding the opponent's ongoing detection tactics, such as dynamic watermarking, and developing a counter‐strategy. To answer the first question, we propose a data‐driven framework that calculates the accurate dynamic model used in stealthy false data injection cyber‐attacks, including zero dynamics attacks, covert attacks, and replay attacks. To address the second question, we present a scheme against the dynamic watermarking defense strategy, which typically detects replay attacks. We validate the methods introduced in this study through an experimental setup of a cyber‐physical system, which includes an omnidirectional mobile robot, a wireless network router, and a remote control center.

Research on Secure State Estimation and Recovery Control for CPS under Stealthy Attacks

“…Nevertheless, it is worth noting that current research endeavors in the field of CPS security defense tend to focus on isolated facets, thereby neglecting a holistic and all-encompassing approach. In this paper, we examine a particular scenario in which a CPS with multiple sensors is susceptible to stealthy cyber attacks, including zero-dynamics attacks, covert attacks, and replay attacks [30]. To tackle this issue, we present a comprehensive framework for the process of security defense.…”
