摘要:

从网络攻防对抗的实际场景出发,针对具有不完全信息约束的多阶段动态攻防过程,构建了多阶段攻防信号博弈模型.针对多阶段攻防过程中信号作用衰减的问题,提出信号衰减因子进行量化描述.在此基础上,设计了多阶段攻防博弈均衡的求解方法,并给出了最优主动防御策略选取算法.通过仿真实验验证了本文模型和方法的有效性,并且分析总结了多阶段攻防博弈的规律.

关键词: 网络攻防, 多阶段信号博弈, 信号衰减, 博弈均衡, 防御策略

Abstract:

From the real network attack-defense,aimed at the multi-stage and dynamic attack-defense process with the restriction of incomplete information,the multi-stage attack-defense signaling game model is proposed in the paper.Considering attenuation of the signal effect in the multi-stage attack and defense,signal attenuation factor is proposed for the quantification of attenuation.Based on the above,we design the solution for game equilibrium in multi-stage attack and defense.Then the algorithm of optimal active defense strategies selection is proposed.Finally,a simulation experiment is conducted to verify the effectiveness of the model and method proposed in the paper,through which some rules in the multi-stage attack-defense game are concluded.

Key words: network attack and defense, multi-stage signaling game, signaling attenuation, game equilibrium, defense strategies
