摘　　要：为了有效评估威胁发生的各阶段系统的可生存能力,提出了一种基于随机博弈模型的网络可生存性跟踪评估方法。通过分析网络、威胁及用户的行为特征,建立基于随机博弈的三方博弈模型,根据系统状态变化情况计算三方收益,在此基础上量化系统的可生存性。最后通过实例验证了该方法可以有效地对可生存性进行跟踪评估,并为保证系统正常运行提供可靠依据。To assessment the network survivability in every stage of threat efficiently, a network survivability tracking assessment method based on stochastic game model is proposed. By analyzing the behavior of network, threat and normal network clients, a three player game model is established. Then the network survivability is quantified on the basis of utility calculation which according to the network state transition. A representative network example is provided to verify the validity of proposed method in the assessment of network survivability and the reliable basis providing for the normal nmning of network.
