Design And Implementation Of The Authentication And Accounting System For WLAN In Campus Network

With the progress of science and technology and the development of the times, more and more wireless personal terminals are used in the campus. It is an urgent need to provide WIFI access to the campus network WLAN. However, there is a great security risk in the open campus WLAN. The incidents caused by WLAN management are also common, so it is necessary to research the WLAN authentication and billing technology in campus network, and explore new management mechanism and technical means. Based on the characteristics of the campus network environment, according to the diversification of wireless terminal and management needs, this paper designs and implements the WLAN authentication and billing system, which is designed and implemented. Some creative work has been carried out:First, Analysis of the characteristics and needs of the campus network WLAN application and put forward to the functional requirements mode of campus WLAN authentication and billing system that meet the needs of a variety of authentication control mode, unified identity and a variety of billing methods.Second, analyze and designs the function module of the authentication and accounting system with Use Case, perform the logical design and physical design of the main data table. And then realize the main function modules of the system, and programming for the functions of some specific representative modules.Third, describes the principle of the campus WLAN authentication and accounting system, and establishes the test environment, tests the function of the system and finally summarizes the analysis.
