Abstract:

Web Services are a new kind of Web application in business. With the development of Web Services there are more and more requesters and services. How to protect the services and how to choose the honest requesters through thousands of requesters are very difficult and important. The existing trust management mechanism cannot publish the dishonest requesters due to its poor identification and punishment functions. In order to solve the issue of lacking effective punishment to malicious requesters in Web Services, this paper proposes a trust management mechanism based on feedback and time decay, which can encourage the requesters to provide honest access behaviors, effectively avoid damaging to the services, and enhance the security of access control in Web Services.

Key words: Web services;trust management;feedback;time decay
