| Along with the popularity and development of information-based application degree, there are more and more application and service base on digital campus, such as web teaching, virtual community, e-books, video conference, VOD system, "one card" system and so on. In addition the expansion of internet user, host number and requirement about bandwidth also challenge to administration of digital campus. In recent years, existence of unsafe factors, for example, the spread of computer virus, hacking, network attacking, information bearing are full proof of unsafe of open network system, and ring the alarm to the security architecture of digital campus. At the same time, the contradiction between share information and data secrecy makes it difficult to keep the network information safety. So it is a focus to build an information system which can adapt the safety running of digital campus.The theies aims to investigation and design of uniform identity authentication system in accordance with the character of digital campus, requirment of defense and related theory and technology.The chief contents of the paper are:(1) It introduces the theory and technique about information security, analyzes the technique of uniform identity authentication system and access control and compares their characters and applications.(2) It takes a Demand Analysis to uniform identity authentication system of Anhui Vocational college of Electronics and Information Technology, gives the logic architecture and layered structure, and selects the appropriate technology pathway.(3) It refers design project of uniform identity authentication system, details the system structure, function module, data structure and interface and solves the critical problems.The uniform identity authentication system has been applied to Anhui Vocational college of Electronics and Information Technology. Industrial test indicates this system can authorize and certificate the user, which provides the security of system. |
