Abstract: The reuse of component-based software is an effective way to improve productivity and quality, and it has been widely used in the computer system. With the improvement of software quality, the research of trusted component has got more and more attention. The credibility of component determines the quality of software. Only those components with high credibility will meet the need of high quality software. So, this paper introduces the ISO/IEC25010 software quality model firstly, then studies the properties of components, and finally a trusted component model based on specific areas is established. After that, this paper explores the selection process of its metrics and describes the credibility of the model with the method of formalization.
