This article studies novel attack and defense strategies, based on a class of stealthy attacks,
namely the zero-dynamics attack (ZDA), for multiagent control systems. ZDA poses a …

This paper studies the detectability of cooperative zero-dynamics attacks, in the context of
coupled harmonic oscillators. A defense strategy, which consists of a strategic topology …

This two-part paper considers strategic topology switching for security in the second-order
multi-agent system. In Part II, we propose a strategy on switching topologies to detect zero …

This paper studies strategic topology switching for a second-order multi-agent system under
zero-dynamics attack (ZDA) whose attack-starting time is allowed to be not the initial time …

This paper analyzes stealthy attacks, particularly the zero-dynamics attack (ZDA) in
networked control systems. ZDA hides the attack signal in the null-space of the state-space …

Undetectable attacks are an important class of malicious attacks threatening the security of
cyber-physical systems, which can modify a system's state but leave the system output …

For large-scale networked systems, see eg, social networks and power networks,
centralized measurement (sensing) and control are not feasible, and hence require the …
