DS Theory-Based Software Trustworthiness Classification Assessment

Software trustworthiness Evaluation has become a research focus nowadays. Referencing the TRUSTIE Software Trust Classification Specification and Trust Evidence Framework Specification, we proposed a software trustworthiness classification assessment method based on DS theory. In this method, the uncertainty and evidences combination which are important during the evaluation but rarely considered by existing studies are taken into account, and DS combination rule and Shannon entropy are applied to address the problems. The simple example shows that this method is effective for ranking trustworthiness of software which is developed following the principles of software life cycle model.
