摘　　要：利用博弈论原理,分析Ad hoc网络入侵防御系统与攻击者之间的攻防过程,建立了多阶段动态博弈下的网络风险预测模型。综合考虑Ad hoc网络不同节点与不同攻防措施对网络风险影响的差异性,量化攻防效用矩阵;通过求解纳什均衡,得到攻防双方最优混合策略;根据风险值求解算法,预测攻防平衡下的网络风险值。仿真实验表明,该模型和算法切实可行,对提升Ad hoc网络安全有一定参考价值。With the principle of game theory,the attack and defense process between the intrusion prevention system of Ad Hoc network and the attacker is analyzed,and the network risk Prediction model under the multi-stage dynamic game is established.In quantifying the utility matrix of attack and defense,the difference of the influence of different nodes of Ad hoc network and different attack and defense measures on network risk is considered.By solving Nash equilibrium,the optimal mixing strategy of both attack and defense is obtained.Finally,the network risk prediction value under the attack and defense balance is predicted based on the risk solving algorithm.Simulation results show that the model and the algorithm are feasible and there is certain reference value for improving Ad hoc network security.
