Like other open computing environments, web services need a scalable method of determining authorized users. We present desiderata for authorization facilities for web services, and analyze potential ways of satisfying them. We propose a third-party authorization system for web services based on trust negotiation, discuss its implementation using the TrustBuilder runtime system for trust negotiation, and present performance results from a stock trading application.
