| With the rapid development of mobile Internet technology and the updating and iteration of intelligent terminal equipment,the application of Wi Fi is closely connected with daily life.In public places,it is necessary to ensure the privacy and security of user connections through network authentication.In the current network authentication scheme,portal authentication scheme is the most popular because of its fast construction,low maintenance cost,but it is most common for wireless terminals In the process of testing and developing wireless terminal equipment,a set of portal authentication simulation system is needed to restore the basic scenarios and some special scenarios of portal authentication.Under the background of the horizontal cooperation project "design and implementation of portal simulation authentication system based on WIFI",after completing the process test of WIFI protocol,this paper makes more research on the design and implementation of portal simulation authentication system,from the introduction of portal authentication related technology to the overall structure design of the system to the design and implementation of each functional sub module,and finally through the each function sub module and system performance are tested to verify the correctness of each functional sub module and the stability of the system.In this paper,the upper computer side functions shared by the Wi Fi protocol test system and the portal simulation authentication system mainly have two functions,namely,the AP message receiving,parsing and classification storage functions and the general test template editing and sending functions.The function of AP message receiving,parsing and classified storage is to receive the messages reported by AP side,then classify,parse and store them.The function of general test template editing and sending is to edit and send the configuration information of AP and the state information of general state machine to AP on the user interface,so as to start the work of authentication test system.The portal simulation authentication system based on Wi Fi protocol test system is composed of authentication server and AP host besides the upper computer side.The function of the authentication server side is to provide the authentication page redirected by the test terminal and to verify the validity of the credentials sent by the AP host.The AP host implements the analysis of the test template of the upper computer and a series of works of portal authentication for the access of the test terminal.This paper first introduces the research background and significance of portal simulation authentication system and the research status at home and abroad,and gives the main content of this paper;then it introduces the portal authentication process,HTTP /HTTPS protocol message format,portal simulation authentication system related technology status and development environment;after introducing the related technology,it gives the problem analysis and goal realization of the simulation authentication system,then it analyzes the requirements of the upper computer,AP host and authentication server of WIFI protocol test system and portal simulation authentication system,and introduces the overall design of Wi Fi protocol test system and the overall design of portal simulation authentication system based on Wi Fi protocol test system,introduces the relationship between various functional modules,gives the structure of each module,and then gives the basic user authentication The design of function module,firewall control module,response message control module,HTTPS redirection module,message receiving classification module and test template is realized.Finally,the performance of each function module and system is tested.The realization of each functional module in this paper provides technical support for the second phase of the project "design and development of portal simulation authentication system based on Wi Fi protocol test system". |
