摘要：
Due to the stealthiness behavior, false data injection (FDI) attacks severely threaten the security of cyber-physical systems (CPS). From the attackers' perspective, this paper mainly studies how FDI attacks impact the stability of CPS. First, we give the FDI attack model where the false control and measurement data are injected into the forward and feedback channels, respectively. Then, we propose an FDI effectiveness model to quantify the attack impact on the state estimation and measurement residue of CPS. On this basis, we design a coordination strategy associated with attack vector and further derive the theoretical attack conditions to manipulate the stability of CPS, which are related to the stability of attack matrix H and system matrix A and the selected moment of time parameter ka. Finally, numerical simulations indicate that FDI attacks can effectively manipulate the stability of CPS including two classes of controlled plants: stable and unstable. This study further reveals the coordination behavior of FDI attacks, which provides important reference for securing the CPS and defending cyber attacks. Copyright © 2019 Acta Automatica Sinica.
