Moving Target Defense for Detecting Coordinated Cyber-Physical Attacks on Power Grids via a Modified Sensor Measurement Expression

This paper proposes a modified sensor measurement expression for moving target defense (MTD) strategy to detect coordinated cyber-physical attacks (CCPAs). Essentially, the MTD characteristics detecting false data injection (FDIAs) differ from those used CCPAs. In first case, performance in FDIAs at attack-execution stage is mainly considered, which generally denoted by detection probability; however, whether construction of undetectable CCPAs disrupted via during attack-preparation focus latter case. There has been little work on context post-activation. our work, novel approach proposed. First, production mechanism without application an transferred that occurs after activation; then, based in-depth analysis CCPAs’ activation, presented Extensive simulations were conducted three standard power systems verify effectiveness and simplicity
