DATA SERVICE-ORIENTED ADAPTIVE INTRUSION RESPONSE GAME METHOD AND SYSTEM THEREOF

摘要

Disclosed are a data service-oriented adaptive intrusion response game method and a system thereof, which are mainly used for solving the problem of adaptive response for a network attack of data service. The method provided in the present invention is used to construct a game model of a detection system and a user, so as to determine whether there is a pure-strategy Nash equilibrium, and if not, a hybrid strategy of the detection system is established, and then a payoff function between the two is established to solve an optimal first-order condition, thereby deriving a Nash equilibrium value of optimal response of two parties of the game, and obtaining an optimal response policy to respond.
