Abstract:

Aiming at the problem that unknown information makes the optimal defense strategy difficult to select accurately in an unknown network attack and defense scenario. By analyzing the network attack and defense game with incomplete information, firstly,theattack and defense evolutionary game model with an exploration mechanism is constructed. Then, based on Q-learning replication dynamic equationswithexploration of Boltzmann,the dynamic evolution equations ofattack and defense decision are constructed. Finally, the optimal defense strategy selection method is given by solving the evolutionary stable equilibrium, and the evolutionary trajectory of attack and defense strategies are described.The simulation experiment results show that the generated optimal defense strategy has better interpretability and stabilityfor small-scale local area networks, when the exploration degree parameter is around 10, which can enable the defense subject to obtain the maximum defense benefit.

Key words: network attack and defense, incomplete information, evolutionary game, Q-learning replication dynamic equation, optimal defense strategy
