Research On The Unified Identity Authentication In University Digital Compus

With the University of the rapid development of information technology, digital campus construction have been planning to enter colleges and universities. Digital Campus building covered a wide range of basic information including the school in all aspects of construction, from the network infrastructure, teaching resources, as well as various operational systems need to be integrated in order to achieve "data centralization, equipment cluster, the application integration, "the effect of information sharing and avoid redundant construction.To achieve the goal of application integration, first of all is to achieve the unification of the various application systems and unified import user names, passwords, which put forward a unified identity authentication system needs.In this paper, Digital Campus of colleges and universities at home and abroad, as well as the unified identity authentication technology made a detailed analysis, pointing out that unified identity authentication has important position in digital campus building, one of the three major software platform. Papers give careful analysis of uniform identity authentication technology, and analysis the relationship of uniform identity authentication and single sign-on and empower. Combination of the Third Military Medical University Digital Campus building of the overall situation, as well as the demand for a unified identity authentication, in accordance with actual needs, designed and implemented a set of SOA-based framework of the use of LDAP for the unified identity authentication system. The system provide a unified identity authentication services for the application of the school. Applications can directly access the authentication service can also call the Webservice way to achieve the certification service. YALE CAS system also provides a single sign-on services, achieved through a user interface, carry out a landing application to access all system.Paper describe in detail of unified identity authentication system used in the specific technology, the key issues. Papers also the actual situation of different applications, providing a different call methods and different ways to authorize the control and given full consideration to the issue of the safety of the system. Finally, the actual show that the use of the programs and technology is feasible.In the traditional campus network construction, the application system is designed to isolate, identity authentication function is to repeat the design and realization of distributed systems in various applications, resulting in a lot of time and waste of funds. In this paper, a unified identity authentication of the study and solve the problem, and the software of paper used for all the program is the free open source software, easy to promotion, has a strong practical..
