摘要:

目前,基于博弈理论的网络安全研究大多采用静态博弈或多阶段动态博弈模型,不符合实际网络攻防连续对抗、实时变化的特点,为了更加贴近攻防实际进行安全威胁预警,借鉴传染病动力学模型分析安全威胁传播过程,基于定性微分博弈理论构建网络攻防博弈模型,推演安全威胁动态变化趋势。在此基础上,提出攻防定性微分博弈求解方法,构造攻防界栅以及捕获区和躲避区;引入多维欧氏距离,度量不同安全状态的威胁严重程度;进而设计预警算法,实现对网络安全威胁的动态预警,且具有更好的准确性和时效性。仿真实验结果表明,所提模型和算法有效且可行。

Abstract:

Most current network security research based on game theory adopts the static game or multi-stage dynamic game model,which does not accord with the real-time change and continuity of the actual network attack-defense process.To make security threats warning more consistent with the attack-defense process,the threat propagation process was analyzed referring to the epidemic model.Then the network attack-defense game model was constructed based on the qualitative differential game theory,by which the evolution of the network security state could be predicted.Based on the model,the qualitative differential game solution method was designed to construct the attack-defense barrier and divide the capture area.Furthermore,the threat severity in different security states were evaluated by introducing multidimensional Euclidean distance.By designing the warning algorithm,the dynamic warning of the network security threat was realized,which had better accuracy and timeliness.Finally,simulation results verify the effectiveness of the proposed algorithm and model.

Key words: network security threat, network attack and defense, threat warning, qualitative differential game, warning algorithm
