Advanced Bad Data Injection Attack and Its Migration in Cyber-Physical Systems

Switching and Data Injection Attacks on Stochastic Cyber-Physical Systems: Modeling, Resilient Estimation and Attack Mitigation

In this paper, we consider the problem of attack-resilient state estimation, that is to reliably estimate the true system states despite two classes of attacks: (i) attacks on the switching mechanisms and (ii) false data injection attacks on actuator and sensor signals, in the presence of unbounded stochastic process and measurement noise signals. We model the systems under attack as hidden mod...

Design and Implementation of Attack-Resilient Cyber-Physical Systems

In recent years, we have witnessed a significant increase in the number of security related incidents in control systems. These include high-profile attacks in a wide range of application domains – from attacks on critical infrastructure, as in the case of the Maroochy Water breach [1], and industrial systems (e.g., the StuxNet virus attack on an industrial SCADA system [2], [3]), to attacks on...

Optimal Denial-of-Service Attack Scheduling in Cyber-Physical Systems∗

Security of Cyber-Physical Systems (CPS) has gained increasing attention in recent years. Most existing works mainly investigate the system performance given some attacking patterns. In this paper, we investigate how an attacker should schedule its Denial-of-Service (DoS) attacks to degrade the system performance. Specifically, we consider the scenario where a sensor sends its data to a remote ...

Relaxing Integrity Requirements for Attack-Resilient Cyber-Physical Systems

The increase in network connectivity has also resulted in several high-profile attacks on cyber-physical systems. An attacker that manages to access a local network could remotely affect control performance by tampering with sensor measurements delivered to the controller. Recent results have shown that with network-based attacks, such as Man-in-the-Middle attacks, the attacker can introduce an...
