This paper addresses the issue of data injection attacks on control systems. We consider attacks which aim at maximizing system disruption while staying undetected in the finite horizon. The maximum possible disruption caused by such attacks is formulated as a non-convex optimization problem whose dual problem is a convex semi-definite program. We show that the duality gap is zero using S-lemma. To determine the optimal attack vector, we formulate a soft-constrained optimization problem using…

Risk-averse controller design against data injection attacks on actuators for uncertain control systems

This paper uses the Conditional Value-at-Risk to characterize the risk associated with the impact of attacks and proposes a convex optimization problem that approximately solves the design problem with probabilistic certificates.

Zero-Sum Game-Based Optimal Secure Control Under Actuator Attacks

This article investigates the zero-sum game-based secure control problem for cyber–physical systems (CPS) under the actuator false data injection attacks and derives the optimal defending policy and the attack policy from the dynamic programming approach.

Stealthy Adversaries Against Uncertain Cyber-Physical Systems: Threat of Robust Zero-Dynamics Attack

This paper first interprets the (non-robust) conventional zero-dynamics attack based on Byrnes–Isidori normal form, and then presents a new robust zero-D dynamics attack for uncertain plants that does not require the exact model knowledge anymore.

Cyber-Physical Attacks With Control Objectives

This paper formulate a cost function that reflects the attacker's goals, and, using dynamic programming, shows how an attacker can design optimal attacks to balance the control objective and the detection avoidance objective.

Constrained Differential Games for Secure Decision-Making Against Stealthy Attacks

Pontryagin's minimum principle is employed to obtain the defense policy that optimizes the system performance and the attack policy that manipulates the future evolution of the system while optimally exploiting the information asymmetry present in the game.
