With the continuous promotion of the degree of application of information technology and in-depth applications and services based on the digital campus , more and more , such as online learning , virtual communities , digital books , video conferencing , video on demand , card systems increasingly emerged ; addition , online users , the number of hosts and the rapid expansion of the network bandwidth requirements , the management of digital campus challenge is particularly reflected in the network security . In recent years, the ravages of the various types of computer viruses , hacking , cyber attacks , information theft and insecurity of existence , are fully exposed the insecurity of the Internet open network system , further digital campus security system sounded the alarm. The same time , the sharing of information , accessibility and confidentiality of information inherent contradictions inherent , making the network confidentiality of information management has become increasingly difficult . Thus, the establishment of a set of adaptation to solve a hot issue in the safe operation of the digital campus information system is urgently needed in the construction of digital campus . In this paper, the characteristics of the digital campus and security needs , the application of information security related theories and technologies , unified authentication system research and design . The thesis completed work as follows : (1) describes the theory and technology , information security and unified authentication and access control technology made ??an in-depth analysis and research , and their characteristics and applications are discussed and compared ; (2 a detailed needs analysis ) Anhui Electronic Information vocational and Technical College unified authentication system , given the logic of the system architecture and hierarchy , the implementation of the technology roadmap ; (3) gives a unified user management and authorization system the design scheme, a detailed discussed of a system configuration of the system , the solution to the functional modules , data structures, and interface design , and key issues are discussed . Designed unified authentication system has been applied to a digital campus Anhui Electronic Information Vocational and Technical College , the practice shows that the system can effectively unified authorized user authentication to ensure the security of the system .
