Security Framework for Cloud Control Systems Against False Data Injection Attacks.

This paper analyzes the security problem of cloud control systems (CCSs), where a malicious false data injection (FDI) attacker may deteriorate the system performance by tampering with the measurements being transmitted. The CCS defender allocates defense budgets among nodes to ensure the safe operation of CCSs. The strategic interactions between the FDI attacker and the CCS defender are modeled as a Stackelberg game, and the optimal strategies for both sides are analyzed in the sense of Nash equilibrium. Numerical examples illustrate the main results of this paper.
