An entropy based approach for software risk assessment: A perspective of trustworthiness enhancement

Software risk management is an important approach to obtain trustworthy software. In this paper, entropy was applied to uncover the reasons of chaos and gave the mechanism of risk management in development life cycle. Information entropy was introduced to assess risk uncertainty and a three-dimension risk assessment was obtained through a questionnaire survey. The finding of the study shows the necessity and importance of risk management for enhancing software trustworthiness. Additionally, risk uncertainty is a new assessment of software risks, providing a view of analyzing risk in software development process.
