Design And Implementation Of The Unified Identity Authentication System

With the rapid development of internet, a number of the digital applications, such as E-Business, E-Government, OA, are growing up in the global range. The mode of life is also profoundly changing. However, the status of the network security is becoming worse at the same time. Furthermore, the security problems restrict the farther development of the Internet. The identity authentication is very important in the network security.The main research in this paper is to set up the unified authentication system which can complete unified authentication and authority and administer. This paper proposes a realized unified authentication frames on the basis of LDAP and Web service, which utilizes technology of the catalogue to realize the unified management to the network user and network application; and encapsulates authentication serve on a Web service with SOAP. So, many application systems can convenient realization long-distance transfer. Besides, offers to Web service's support of realizing the frame. In the design, the thought of single singn-on was put forward and soluted based the Kerberos. 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 dificulty of system developing. Java language was used for programming at this paper. This paper indicates the each key fanction implementation method. With the unified identity authentication system being perfected, it will play an important role among the information safe system of campus network.
