ABSTRACT
In the Internet, there are a mass of malicious, fraudulent services in addition to the dynamics change and differences in service of quality. As a result, it is difficult for a client to fastly get high- quality services. In this paper, a service-composition framework based on the trust evolution and alliance has been proposed. It is different from traditional service workflow model. The trust relationship will be built after the trust evolution between services requester and provider. The trust services requester and provider are going to form an alliance through the relationship, so the malicious, fraudulent services will be excluded from the system and the service-composition will be carried out in a trust environment. On this basis, a strategy measuring the trust relationship among the services based on information entropy has been proposed, which can avoid the deficiencies of multi-dimensional trust indicators simply weighted in the previous studies. Theoretical analysis and experimental result show that the method proposed in this paper is more superior in credibility and security, comparing to the traditional services selection methods.
