摘　　要：如何保证软件可信性是目前软件工程研究领域的热点话题之一.从逆向思维的角度围绕软件失信展开三方面的研究.基于软件可信性的概念,分析软件失信及失效、故障、缺陷、错误之间的关系,进而提出"失信因子"这一新的概念;通过分析失信因子与软件风险因素内涵的差异,指出了失信因子概念提出的基础性和重要性,并给出软件失信链,延伸了传统的失效链;通过构建一种基于WBS-RBS的识别框架探讨了对失信因子收集、识别和分类的方法.结合示例.验证了所提概念的合理性.特别强调,在软件开发过程中,软件可信性的保障应着眼于控制、改善失信因子这一根源性的因素,而非缺陷和故障等表征现象.How to ensure software trustworthiness is one of the hottest topics in the software cngineering research at present. Three aspects on software distrust are studied from converse thinking, Based on the concept of software trustworthiness, the relationships among software distrust, failure, fault,defect and error are analyzed. Furthermore, the concept of distrustable factor is proposed originally. With the analysis of difference between distrustabie factor and software risk factor, the basics and importance of distrustable factor are emphasized. The distrust chain of software is given, which is the extension of the classic failure chain. A new framework based on WBS-RBS is proposed to collect, identify and classify the, distrustable factors. The reasonableness of the concept that proposed in the paper is verified by a case. It is specially pointed out that guaranteeing the software trustworthiness should focus on controlling and improving the original source - distrustable factor,instead of defect and fault.
