摘要
由于灰色层次分析法的近似特性被许多研究者用来解决多维信息问题,文中提出了顾及灰色层次分析法的多维信息安全指标体系及等级保护量化模型。针对不同维度信息的多元性建立了安全指数(Safety Index,SI)、保护模式(Protection Mode,PM)和等级保护量化率(Grade Pro-tection Quantizing Rate,TP)来表征多维信息的多元性差距,使用灰色层次分析法与灰色系统理论对该模型进行求解,使结果更为客观。与使用传统方法的模型相比,该模型具有易于量化、可操作性强等特性。
Because of the approximate characteristics of the grey analytic hierarchy process,it has been used by many researchers to solve multi-dimensional information problems. This paper presents a multidimensional information security index system and hierarchical protection quantitative model taking the grey analytic hierarchy process into account. In view of the diversity of multidimensional information,a safety index( SI),a protection mode( PM) and a graded protection quantization rate( TP) are established to represent the diversity gap of multi-dimensional information. The grey analytic hierarchy process and the grey system theory are applied to the mode,and the results are more objective.Compared with the traditional method,the model is easy to quantify and handle.
