Abstract

A service is rigorously trusted if it can provide firm evidences to its users about its behavior. The evidences ensure that the service really follows its claimed behavior to process the requests and sensitive input data from users. In this paper, we propose a framework, which can attest the behavior of web services according to the trust policies specified by users. Different users may concern different aspects of service behavior. By using policies, this framework allows user-specific behavior attestation. In addition, this framework also protects service providers. When a user sends a service request, the framework needs the user to show that he has agreed on the service behavior. A case study is used to describe the critical processing steps of the framework to deliver rigorously trusted services.
