Model of Cross-domain Service Access Based on Security Token Service
Ian D · Microcomputer Information · 2008
By popularizing the Internet,the problem of cross-domain service access has become crucial.A module of secured service is proposed to support access crossing heterogeneous regions based on web service security token service model.Also,the design principle of system architecture as well as service runtime mechanism is emphasized.Then two critical problems are discussed,including locating mechanism of security token by WS-Trust extension and defining interfaces of security token provider to abstract the variety of security authenticator.Finally,with the basis of this service prototype,the convenience and expansibility are proved through implementing under grid interoperability scenarios.
