基于层次分析法-灰色聚类的无线网络安全风险评估方法

Risk Evaluation of Wireless Network Security Based on AHP-grey Clustering Method

无线网络安全风险评估由于各类评价指标的子因素较多,且存在模糊性和相对性,采用传统的风险评价方法难以达到直观量化的要求.采用基于层次分析法(AHP)和灰色聚类相结合的风险评估方法,首先对无线网络中的各种安全聚类指标进行层次化分析,量化出各层指标的权重,再采用灰色聚类的方法进行聚类分析,得出无线网络的风险值,从而确定网络的安全情况.结果表明,该方法是一种有效的无线网络安全风险评估方法.

For the purpose to evaluate the security of wireless networks,we have to consider many evaluation indexes,many factors are ambiguous and relative.Therefore it is difficult to achieve quantitative assessment requirements intuitively by using traditional methods of risk evaluation.This paper proposes a model based on analytic hierarchy process（AHP） and gray clustering.Firstly by analyzing various security indexes hierarchically,we can quantify the weight of indicators of every layers,and then using the gray clustering to get clustering analysis,finally,we can determine the network security situation through obtaining risk clustering indexes.This method is proved to be efficient in wireless network security risk assessment.
