Side Information-Based Stealthy False Data Injection Attacks Against Multi-Sensor Remote Estimation

Dear Editor, This letter investigates a novel stealthy false data injection (FDI) attack scheme based on side information to deteriorate the multi-sensor estimation performance of cyber-physical systems (CPSs). Compared with most existing works depending on the full system knowledge, this attack scheme is only related to attackers' sensor and physical process model. The design principle of the attack signal is derived to diverge the system estimation performance. Next, it is proven that the proposed attack scheme can successfully bypass the residual-based detector. Finally, all theoretical results are verified by numerical simulation.
