摘要
为反映网络攻防对峙形势并解决策略相依问题,提出不完全信息的动态攻防博弈模型。通过扩展对象Petri网的定义,使变迁及其输出弧上携带攻防策略及其效用信息,定义网络攻防对峙模型。在定义攻防行动顺序的基础上,提出利用攻防对峙模型构建博弈扩展形的方法,据此可得到攻防博弈均衡策略。
To reflect network attack-defense confrontation situation and solve the problem of strategy dependence,an incomplete information dynamic attack-defense game model is proposed.It constructs network attack-defense confrontation model,and based on the definition of attack and defense actions’ sequence,the method of conversion from attack-defense confrontation model into extensive form game model is presented,then equilibrium strategy solution can be acquired.
