Research on Game Theory of Air Traffic Management Cyber Physical System Security

For the air traffic management cyber physical system, if an attacker successfully obtains authority or data through a attack, combined with attacks, it will cause serious consequences. Game theory can be applied to strategic interaction between two parties, especially parties have different goals. The offensive and defensive game process of system is non-cooperative incomplete information dynamic game. choose camouflage type attack launched. detection device configured in has certain probability that detected. According detected, defender updates posterior belief selects corresponding protective strategies. offense defense, Bayesian model established, possible perfect Nash equilibrium its existence conditions are solved, complete mathematical constructed. analysis shows help quickly obtain strategy reduce loss as much possible.
