Design And Implementation Of Unified Identity Authentication Information System Based On Web

With the growing population of computer and the development of information technology, constructions as well as renovations are deeply promoted in armed police officer school. Applications and services applied on the digital campus network are increasing rapidly. While the applications improves the operational efficiency of school, problems are raised to the school management. Because of the distrust of each account system, one who want use different services has to log in from different entrances. Therefore, each user has to memory lots of usernames and corresponding passwords which is quite inconvenient and unsafe. On the other hand, the system administrators have to maintain each system to guarantee data consistency. Errors and bugs will increase gradually and the rate of users’ information illegally interception and destruction will also increase during the rapid increase of applications on systems. Thus seriously restricting the further development of network applications.This thesis aims at establishing a unified identity authentication system for universities and implementing unified management, unified authentication and unified authorization. Based on the analysis of the actual status of identity authentication and school situation, a frame which is based on the Web Service is put forward to realize the unified authentication. Using SOAP to encapsulate the authentication service to a Web service so as to realize the application system do remote call conveniently. At the same time, a solution is given for identity authentication through CA certificate and single point login through bill.This thesis, firstly, analyzes the present research situation of unified identity authentication, and then introduces the related technology of identity authentication and its implementation. Then present a practical architecture of unified identity authentication system based on school requirements. With the basis of that, the system’s implementation is given which uses the Struts framework of J2 EE with the design pattern of MVC. The part of system implementation will emphatically introduces the methods and steps on realizing the main function of the system called single point login, user registration, user account, identity authentication etc. The system can integrate different system platforms and effectively organize all kinds of Web applications in campus network under testing, so meet the requirement of school.
