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。

Abstract: 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.

Key words: network security, extended object Petri net, attack-defense confrontation model, dynamic game
