一种可信属性之间的相关性分析方法

摘要

As the software plays more and more important roles in today′s information society,the software reliability are strongly required.Software trustworthiness can be described and expressed by the trustworthy attributes,and many sets of trustworthy attributes are proposed based on the different features and aspects of the software systems.An approach to representation and correlation analysis of trustworthy attributes is proposed.Based on the correlation analysis,a suitable minimum subset can be given from the trustworthy attributes.And the minimum subset provides an effective method for measuring the software trust worthiness.The approach can be used to analyze and measure the correlation of trustworthy attributes.%随着软件系统在信息社会中发挥越来越重要的作用，人们对软件系统的可信性方面的要求也愈来愈高。软件可信性可由软件可信属性集来进行描述和表示，但是人们根据软件系统的不同特征和不同层面提出了很多软件可信属性集。为此，本文提出一种软件可信属性的表示以及相关性分析的方法，给出了可信属性相关性、独立性和冗余性的概念，并基于相关性分析可以从所知的属性集中构建一个适合的可信属性最小子集作为对软件可信性进行评估的指标。此方法能够很好地对可信软件属性之间的相关性进行分析与度量。
