资源受限下的网络安全动态博弈模型

Dynamic game model of network security under resource constraints

针对网络安全中攻防冲突双方信息获取不完整问题,在假定总资源受限的情况下,建立了网络攻防对抗博弈模型,提出了一种求解纳什均衡及代价函数的算法。通过案例,分析并验证了模型中纳什均衡的存在性及有效性。该方法可为不完全信息、资源受限情况下博弈过程策略选择问题提供借鉴。

Aiming at the incomplete information for attack and defense in the network security,it establishes the game model under the assumption of the limited total resources,proposes an algorithm to solve Nash equilibrium and cost function.Based on the case it analyzes and verifies the existence and validity of Nash equilibrium.This method provides some reference for the strategy under the condition of incomplete information and limited resources in game model.
