Research of ESB-WSFM Cross-Domain Authentication Model in SOA

In order to solve the cross-domain authentication problem in SOA, this paper analyzed the theory and features of SOA technology, studied the cross-domain authentication mechanism of WS-federation, combined the feature of ESB in SOA, expanded the function of ESB by adding authentication center, improved the mechanism of WS-federation, proposed the cross-domain authentication model which bases on WS-federation and adopts ESB as the reliable third-party. This model is suitable to SOA and has the advantages of centralized trust management and authentication as a bus.
