基于演化博弈模型的网络攻防策略

针对网络信息安全问题中攻防冲突行为的博弈现象,研究了攻防双方最优策略的选取方法。根据攻防双方冲突的实际背景,将双方的收益进行量化分析,建立了攻防双方网络冲突博弈矩阵,利用演化博弈理论的基本原理,给出网络攻防对抗的动态过程,求解复制动态微分方程,得到五组均衡解。根据演化稳定策略的性质,分类分析了均衡解的稳定性。利用MATLAB实验平台,选取了满足不同情形下的参数,进行了策略稳定性分析,进而验证了模型的准确性。研究结果为研究网络信息安全中的冲突问题提供了理论依据。

Research on Network Attack and Defense Strategy Based on Evolutionary Game Model

The game phenomenon of attack-defense conflict behavior in network information security problem. According to the actual background of the conflict between the offensive and defensive sides, this paper establishes the game matrix of the conflict between the offensive and defensive sides, and quantifies the benefits of both sides in the model. Based on the basic principles of evolutionary game theory and the nature of evolutionary stability strategy, the dynamic process of network attack defense confrontation is classified and analyzed. Using MATLAB as the experimental platform, the parameters satisfying different situations are selected and the stability analysis is carried out, which verifies the accuracy of the model and provides a theoretical reference for the network information security problems in the real society.
