Integrity Attack With Takeover Local Objects On Multi-agent Cluster Systems

This paper proposes an integrity attack strategy on multi-agent cluster systems. The attacker can take over a specific agent of the multi-agent systems without being detected by the strategy based on the discrete optimal quadratic controller. By designing the attack signal, the state of the target agent can be moved to the desired state, which achieves the takeover goal of the attack. Simultaneously, the residual error between the output of each agent and the estimated value calculated by the monitor in the multi-agent systems is within the alarm threshold, which guarantees the concealment of the attack. Numerical experiments illustrate the attack scenarios and effectiveness.
