Research on the Game Theory based Network Attack-Defense and its Application

The network attack-defense model is important composition of network security. The current-used models usually cannot describe the characters of the interaction and confrontation of the both attack-defense sides, which is the chief drawback. The paper proposes the game theory based attack-defense models, defines the elements and the Nash equilibrium of both side of the game. Using the dictionary-attack as an example, this paper characterizes the confrontation policy and its effective, and the Nash equilibrium as the result of Gambit.
