Design And Development Of Identity Authentication System For Digital Campus Based On LDAP

With the development of the Internet at full speed, the increasing network application makes the network administration more complex and insecurity. The risk of deploying the applications in Internet is recognized and agreed widely. As a solution to the information assembling, categorizing, integrating and internet surfing, Campus Network Portal provides its users, such as students and faculties, with a unified platform to get access to its internal information. On this platform, we can realize the unified identity authentication and administration between the application systems by setting up a unified identity authentication system and Single Sign On system. It is an important link of the construction of information security system of the Campus Network.Firstly, this paper analyzes several typical applied models of Single Sign On system, then draws the conclusion that the integrated and combined abilities of the existing unified identity authentication systems are deficient and unsuitable for the Campus Network. Secondly, this article introduces a kind of Single Sign On system model that is more appropriate to different kinds of enterprises. In the system, LDAP and Web Services are combined to realize an integrated and unified authentication system. In the end, in the section of the functional realization, directory server and the security architecture are summed up at first. Then the idea of Single Sign On is put forward. The emphasis is put on expounding the solutions to the difficulty in the Single Sign On system. Then solutions and focuses which can be partially realized are given. Based on this, an integrated, most useful security-supported platform for great and complicated portal application is designed and realized.The best feature of this paper is to combine the theory and practice which is used in the security construction in the construction of CampusNetwork of Dalian Jiaotong University, that is to say, to analyze the key problems and realize the Single Sign On system in B/S mode and C/S mode.
