The Research And Realization Of “Digital Campus” Uniform Identity System

Under the country to vigorously promote university information office of the call, after years of information technology,many universities have set up their own business applications,large-scale information technology university,but including university portal 5 mail systems, office automation systems,student Management System and professional business applications,including many systems have a separate identity management systems. With the expansion of the application system construction business management processes and university complex, often resulting in the management of digital identities inconsistent information in different systems, which brought many inconveniences for the information management of colleges, universities reduces the efficiency of the office management department, increased the difficulty of system integration and cascade, increasing the information management of the university operating costs. In order to solve the identity information silos college information management, to achieve seamless integration and sharing of information resources, tfie university unified identity management system has become an important part of university-based information technology platform, the process of informatization construction of university unified authentication system being solve the above problems is the basic platform.Identity management systems can be deployed individually or integrated deployment. The system of multiple business systems through decentralized university administrators to integrate digital identities, providing standard read and query status information for different business systems, unified management of digital identities, unified university administration and internal audit management of identity security policies provide a standard interface for applications and services, to achieve a unified, secure, flexible and scalable identity management college management system. This paper presents a unified identity problem solving specific programs, combined with SSO technology, authorization management technology. Web Services technology and authentication technology to give the overall system design, thus completing the system implementation and system testing.In the thesis, the main contents of design and implementation in unified identity authentication system are as follows:(1) The identity-related technologies, including authentication, authentication protocol and related security technologies for Web Service technology, single sign-on technology and rights management technology research;(2) The analysis of campus information technology demand for unified authentication analysis, overall design and architecture of the unified identity authentication system;(3) They describe the key features from the system logic, and they are designed unified rights management. The single sign-on and core business logic class for the realization of the system design of the database structure algorithms and authentication protocols, and optimize system performance;(4) Consider system implementation, detailed definition of the models, methods and program flow, complete algorithm code, and gives the verification process;(5) The system for each unit testing, integration testing, and system and complete the overall test, verify system performance.
