Abstract: A method for analyzing the failure of the network security based on game model is proposed.The failure process of the unrepairable network system can be considered as a single-controller stochastic game.The attacker’s total utility and best strategy are analyzed and calculated,and the result verifies that the attacker will not change his choice when the expected payoffs change in a certain range.

Key words: network security, single-controller stochastic game, linear programming

摘要: 提出了一种基于博弈模型的网络安全性失效的分析方法。针对不可修复的网络系统,安全失效过程被看作一个攻击方控制状态转移的随机博弈过程。从攻击的角度计算分析了在此过程中攻击方的总收益和最优策略,结果表明当支付期望值在一定的范围内变化时,攻击者将不改变其行动选择。
