The Unified Identity Authentication System Based On Web Application Design And Implementation

A large quantity of service and application based on digitalization school networkoccurs for computer universal application and IT evolution which make it possible toconstruct and reconstruct shool informationization.All facilities and applicationprogramming meliorate performance and bring about new school-managedstatus.Every application system not confiding in each other has one creditaccount.Generally speaking, a user is liable to remember various names andpasswords.It is rather inconvenient and unsafe Administrators have to alignusers’information in divers systems.The more application system are,the more mistakesit makes.and the more easily users’information is hijacked,therefore, the safety level ofapplication system goes down.As it is,related net application will be barred severely.This paper focuses on studying how Zhejiang Changzheng vocational and technicalcollege establishes a unified identity authentication system to achieve the user’s unifiedmanagement, authentication and authorization. On the basis of analyzing the situation ofidentity authentication and the actual situation of our college, the article proposed animplementation framework of unified authentication based on Web Service, usingSOAP to encapsulate authentication services as a Web service, so that applications caneasily implement remote calls. At the same time, it gives a solution authenticating theidentity by the CA certificate and singly logging the system on the basis of documents.This paper analyzes the present status of research on unified authentication, andthen describes the authentication and related technologies system implementation.Thenaccording to University requirements, we have designed a practical unifiedauthentication system structure. And on this basis, using struts framework technology ofJ2EE, we implement the MVC design pattern in accordance with the system. In the partof the system implement, we focus on introducing the ways and stages of realizing themain functions in the system such as the single sign-on, account associate, userregistration, user authentication and etc. The system has been tested to meet the needs ofcolleges, to integrate different system platforms, and to organize a variety of Webapplications within the campus network effectively.
