Optimal Injection Attack for UCPS Under Vertical Depth-Keeping Task Via Game Approach

Dear Editor, This letter concerns about the security problem of underwater cyber-physical system (UCPS) for depth-keeping task in vertical plane. A dynamic parametric model UCPS with ocean currents and hydrostatic is considered. With intelligence controller, objective function a zero-sum game between attacker controller introduced. The destroys by injecting designed false data into system. Compared existing attack strategies, gets rid dependence on constructing virtual linear based input output (I/O) data, i.e., measurable depth pitch angle. Note that information such as pressure hydrodynamics force cannot be accessed attackers under environment. In addition, programming method adopted to solve mixed strategies framework. Finally, effectiveness this scheme verified simulation.
