Attack Strategy

Recent researches on data-driven and low-sparsity data injection attacks have been presented, respectively. To combine the two main goals (data-driven and low-sparsity) of research, this paper presents a data-driven and low-sparsity false data injection attack strategy. The proposed attacking strategy (EID: Eliminate-Infer-Determine) is divided into three stages. In the first step, the intercepted data is preprocessed by sparse optimization techniques to eliminate the outliers. The recovered data is then exploited to learn about the system matrix based on the parallel factorization algorithm in the second step. In the third step, the approximated system matrix is applied for the design of sparse attack vector based on the convex optimization. The simulation results show that the EID attack strategy achieves a better performance than the improved ICA-based attack strategy in constructing perfect sparse attack vectors. What is more, data-driven implementation of the proposed strategy is also presented which ensures attack performance even without the prior information of the system.

Distributed control is widely used in AC microgrids to maintain frequency and voltage stability and internal power balance. However, distributed control need realizes information interaction through communication network, which makes microgrid vulnerable to network attack. A distributed control strategy based on consensus theory is proposed in this paper to enhance the resilience of microgrid to attack. An attack detection and localization method is designed for the false data injection attack. The Artstein’s transformation is introduced to process the delay data and the performance of controller under delay can be enhanced. An isolated island AC microgrid model was built in Simulink platform for simulation to verify the performance of the controller. The simulation results verified the effectiveness of the control strategy against false data injection attack and time delay.

False Data Injection Attack

Abstract An adaptive resilient control is concerned for a class of cyber-physical systems(CPSs) in presence of stealthy false data injection attack s in sensor networks and unknown strict-feedback nonlinear dynamics. As the sensors are attacked by ill-disposed hackers, the exactly measured state information is unavailable for state feedback control. After theory ratiocinations, the initial issue of false data injection attacks is transformed into nonlinear uncertainty dynamics and unknown control directions at the last step. At each step in the recursive backstepping control, extended state observers (ESOs) in active disturbance rejection control(ADRC) are investigated to approximate the lumped system uncertainties. Specially, the Nussbaum functions are introduced at the last step in the adaptive control. All the closed-loop signals are proved to be semi-globally uniformly ultimately bounded by Lyapunov theory. Finally, numerical simulations verify that the proposed control can afford favorable stabilization performance and counter false data injection attack.
