摘要
为了更贴近网络实际,针对当前网络攻防信息不均衡和网络对抗动态性的问题,提出了一种具有主动防御功能的信号博弈模型。在不完全信息约束条件下,通过释放不同防御虚假信号,构建了攻防策略博弈树对攻击者和防御者策略进行了建模,并利用网络伪装信号降低攻击策略的成功率;对存在的各类均衡进行了分析,设计了博弈模型求解方法,并在此基础上给出了最优防御策略。最后,通过仿真实验证明了模型的可操作性和有效性,并对实验结果进行了分析和总结。
In order to get closer to the reality of the network, aiming at the imbalance of information of network attackdefense and the dynamics of network confrontation, a signaling game model with active defense is proposed. In the condition of incomplete information, the game tree of attack-defense strategy is built to model the strategies of attackers and defenders,and the success rate of the attack strategy is reduced by using the camouflage signal. Based on the analysis of the equilibrium,the game model is designed and the optimal defense strategy is given. Finally, through the analysis and summary of the experimental results, the maneuverability and effectiveness of the model are proved.
