Key Technique Research And Practice Of Unified Identity Authentication System In Digitalized School

With gradual construction of digitalized school being perfect, various kinds of network- Based application is taking on. But, due to the drawbacks of different systems independent authentication of application, the centralized management of campus network is difficult to realize. So, setting up a unified identity authentication system, which is used to manage tothe network user in unison, unifying authentication and authorize in unison, is an important measure in the information safe system construction of digitalized school.Existing unified authentication that system utilizes directory service partly solves the problem of unified authentication. However, for its C/S mode based, the system is insufficientin using and integrates. With development of Web Service technology and day by day extensive application, the characteristics with integration, loose coupling and simple realization makes its important effect in application integrations. Use SOAP, we can implement those long-distance Web services very easily. So Lightweight Directory Access Protocol and SOAP offer good support for realizing a unified identity authentication system.This paper proposes a realized unified authentication frame on the basis of LDAP and SOAP, which utilizes technology of the catalogue to realize the unified management to the network user and network application, and encapsulates authentication service to a Web service with SOAP, So, many application systems can conveniently implement remote procedure calls. Besides, it offers the Web Service'support of realizing the frame. The designed system completes data exchange between difference construct databases with XML and SOAP technologies, and realizes the centralized management of user's information. Each tie of the system is relatively independent, which guarantees the loose coupling of the system. In additional, the system can be integrated easily. So, new application system need not rely on it's own authentication system but unified authentication to complete the authentication and authorization of users, and reduces the degree of difficulty of system developing. With the unify identity authentication system being gradual and perfect, it will play an important role among the information safe system of digitalized school, and network management will be simpler and effective.
