摘要: 提出一种基于构件失效建模的软件安全性分析方法,对失效传播与转换标记(FPTN)进行扩展,描述各个构件的失效行为和模式。在架构设计层面综合考虑软件系统的构件连接和结构特性,使用模糊数学的相关方法,确定软件的安全等级。结合实例,对构件失效传播的概率进行计算,结果证明了该方法的有效性。

Abstract: A software safety analysis method based on the component-level failure modeling is proposed. By using the extended Failure Propagation and Transformation Notation(FPTN), the failure behaviors of all components are described. It performs the architectural safety analysis by considering the architectural characteristics of various software system components. The safety level can be determined using the correlative fuzzy method. Combining with the example, the failure propagation probability can be obtained, and the results prove the effectiveness of the method.

Key words: software safety, component, failure modeling, failure propagation
