基于多属性决策的复杂网络节点攻击研究

Complex Network Node Attacking Based on Multi-attribute Decision Making

在复杂网络攻击中,指挥决策者在制定攻击方案时缺乏可靠依据,实施行动时难以达到任务目标效果,针对这种情况提出了一种科学的复杂网络节点攻击效果评估方法。通过对网络攻击中攻击方收益、攻击方损耗、攻击方遇到的风险进行分析,建立了相应的指标体系;利用TOPSIS方法对网络中节点的攻击效果进行综合评估和排序,有效克服了传统节点选取方法中依靠网络拓扑单一指标(如介数、度中心性)进行评价的片面性,为制定网络攻击方案提供了科学依据。

In complex network attacks,the lack of a reliable evidence for decision-makers in attack planning makes it difficult to achieve mission objectives in action. A scientific method for evaluating the complex network node attacking effect is presented. By analyzing the income,loss,and risks of the attacker,we established the corresponding index systems. TOPSIS method was used for making comprehensive assessment and sorting to the attacking effect of the nodes in the network. It can overcome the one-sidedness shortcoming of the traditional node selection method,i. e.,relying on a single indicator of network topology. The study supplies a scientific basis for scheme making in network attacking.
