The rapid development of information technology has made campus network become an indispensable part of university teaching and management, and the application of campus network plays a great promoting effect for the construction and development of university. Good operation of campus network and convenient and effective management of users are a part of prerequisites to ensure the normal operation of works of university.The authentication method of campus network plays a key role in the operation and management of campus network. At present, the authentication method generally adopted by campus network of university has such problems as failure to consider admission control and access control, to consider network stabilization and effective management of users and to consider authentication and billing at the same time. Along with the transformation of campus network to service-oriented network, the existence of these problems makes the conflicts between campus network and university demand more obvious, which hampers the healthy development of campus network. Therefore, it is of important practical significance for the sustainable development of campus network of university to adopt a reasonable campus network authentication method to avoid above-mentioned problems.There are generally three purposes to deploy authentication system in campus network. Firstly, it can judge the legal identity of access users strictly and correctly. Legal identity means that the identity is true, recognizable and administrable. Secondly, it can administrate and control the online behavior of access users to a certain extent. The online behavior includes the website accessed by network users, the online activities done by network users and then network flow used by network users. Thirdly, it can carry out accurate billing for network users and provide various billing strategy. However, the authentication system adopted by campus network of university can not achieve these three purposes totally.The paper introduces the development of campus network of university and the structure and characteristics of campus network firstly. Then it states the principle and process of several authentication methods of campus network generally adopted by university at this stage and points out the problems and shortcomings brought by these authentication methods to campus network. It also indicates the necessity of double identity authentication in the application and development of campus network and designs a program of double identity authentication of campus network through a root cause analysis into the characteristics and shortcoming of the authentication methods of existing campus network. Finally, the paper makes a conclusion that the double authentication method with the combination of 802.1 x authentication and concentrated identity authentication is an ideal authentication method of campus network of university through the analysis and comparison of the comprehensive performance of double identity authentication system and traditional authentication system. It can achieve three purposes of adopting authentication system in campus network, meet the requirements of campus network management, improve campus network of university management and guarantee the good operation of campus network effectively to lay a foundation for campus network of university to transform to service-oriented network.
