Trusted component model and supporting framework based on adaptive mechanism

According to the demand of credibility for the application software in the dynamic environment, the component technology is introduced into the development of the trusted service software to improve the software quality and development efficiency. Firstly, the basic idea to ensure the component credibility is described. Then an adaptive trusted component model is given and described in this paper. And subsequently an adaptive supporting framework is proposed. The framework can ensure the reliable performance of the component, can adjust the structure and behavior of the component depending on the change of runtime context adaptively, and can meet the needs of the upper application. Finally, the adaptive adjustment process of components is given based on the proposed model and framework.
