摘　　要：论文从博弈论的角度出发,首先建立了一个入侵者和入侵检测系统之间的一次性的动态博弈,以此博弈为基础,利用复制动态机制,模拟了博弈方在不同的策略类型下,博弈方策略类型比例动态变化。并且根据模型来预测最终的稳定均衡点,入侵检测系统则可以通过分析和改变成功报警率、成功攻击率、惩罚代价等因素之间的函数关系,进行自我防御来抵抗攻击,从而把损失降到最少。Based on Game Theory, a dynamics Game between Intruders and IDS is set up at first. Then in order to predict the final stable equilibrium, the dynamic changes of Game strategies are simulated in different game strategies among different players by using replicator dynamics mechanism. In order to reduce losses, Intrusion Detection Systems （IDS） could prevent attacks through analyzing and changing the function relations of such factors as success alert rate, the success rate of the attacks, and punishment cost.
