Research On Identity Authentication In Digital Campus

With gradual construction of digitalized school being perfect,va rious kinds of network-Based application is taking on.But, due to the rawbacks of different systems independent authentication Of application,the centralized management of campus network is d ificult to realize.So,setting up a unified identity authentication system, which is used to manage to the network user in unison,unifying authentication and authorize in unison, is an important measure in the information safe system construction of digitalized school。Unified identity authentication system based on directory service introduces LDAP protocol and uses distributed characteristic of directory service, organizes users' information and network resources in a logic tree, which distributed over all application systems. That simplifies communication between authentication center and application systems, and reduces the system's difficulty to realize. Compared with distributed network system centered on database, this method of realizing is extendable and the management to centralize,flexible,and simplified achievement.This paper focuses on the model of uniform campus identity authentication system and the detailed study of the related protocols and technologies. The main content of the research includes the directory service technology, Kerberos authentication technology and campus directory design etc. The feature of this paper is that it combines directory services technology and Kerberos technology and provided a secure model of the uniform campus identity authentication system based on directory services.The realization of this model will not only solve the problems of the uniform identity authentication system of campus networks, but also improve the safety and integrity of the system.
