Research Of Unified Identity Authentication System Of Campus Network Based On The Standard Of Information Resources

Nearly ten years have passed since the building of universities' informatization in China began, now it has come into an overall and fast stage. Along with it, some matters of sharing information and integrating systems come to extrude. Some systems programming were lack when many schools began to design their construction of campus network and all kinds of application systems, a uniform standard system for information resources and construction of application systems was not constituted. So this problem caused the digital campus into a situation from "trucks without road" to "acts blindly","lacks of principle" and "chaos in traffic". Some information resources can't be shared effectively and are used inconveniently, as well as some information systems construction are reduplicated and some information systems management are dispersed.At first, this dissertation analyzes the mature catalog system and exchange system of government information resources, and constitutes an information resources standardization coding system based on the requirement of AnQing Teachers College's informatization. This coding system contains the content of all aspects related to school, such as teaching,scientific research,personnel matters,logistics,students status and etc. and it also pays attention to the system's flexibility and expansibility, which could not only reflect the actuality of informatization construction of the school, but also could provide standard support for the future portal construction. Then we can modularize this coding system, import some authoritative data from the correlative application system of the school, and use the groupwave called Active Directory binded with the windows 2003 operation system to establish directory services database. Finally we can build a platform of unified identify authentication based on the directory services database.The project described in this dissertation is accomplished under J2EE architecture. The crucial key in the project experiment is to conform some heterogeneous application systems, and especially to complete the analysis and alteration of the authentication module and interface, including the three kinds of authentication approaches. The development of the authentication modules and interface ones among application systems and authentication platform is the core mission in the construction.
