The Research And Realization Of Unified Identity Authentication System Based On Web Service In E-Campus

With gradual construction of e-campus being perfect, various kinds of application emerge on the campus network system.The drawbacks of each kind of application system with independent authentication also gradually appears, so the campus network is hard to be centralized management, the visit of user is not convenient, and the security exists enormous hidden danger. Therefore, to establish a Unified Identity Authentication System(UIAS) to the digitized campus that realize unified management, unified authentication and unified authorization is extremely essential.The development pattern and the structure of existing application system are very different, they has very many insufficiencies in the application integration. With the technology development of Web Services, its characteristic that contain highly effective integration, the loose coupling and easy realization and so on cause that mutually to operate and the integrated question is simplified from the level.This article uses massive popular open-source softwares, and proposes one kind of UIAS frame that based on Web Services,it contains three parts, the platform of unified identity authentication, the database of LDAP as well as Web Services integration engine. the platform of unified authentication identity including the CAS server. Through unifying acegi and CAS the authentication and authorization can be realized. In the overall system, the authentication and authorization completely depends on CAS. This can reduce the maintenance and management cost of each application system, enhance the security and extension, and reduce the difficulty of development. Developing Web Services with Xfire can make each level of the system be relative independence.This can guarantee the loose and coupling of system, also cause the integration and extence of application system be easier. With the gradually consummation of UIAS system, it will play vital role in the information security system of e-campus, and will make the network safer, management and use more convenient.
