Research On Safe And Efficient Access Control Technology For Mobile Terminal

With the diversification of the mobile terminal and the popularization of the application,the security of wireless network has already been the focus of people's attention.The current information security issues are becoming increasingly prominent,illegal access,information theft,malicious attacks,and so the network can not run properly.In wireless networks,wireless access is the most vulnerable to attack in the wireless network link,therefore,it is of great significance to improve a wireless access control system which has both security and efficiency.This paper is based on 802.1X EAP-TLS protocol and EAP-MD5 protocol,this paper puts forward the authentication mechanism of the MAC address binding scheme and the double authentication mode,at the same time,the authentication protocol is improved and optimized,and also increased the background management functions.And then design a more efficient and more secure access control model.The test shows that the system not only meets the safety and efficiency,but also has controllability.This paper aims to improve the security and efficiency of mobile terminal access control system.The selected 802.1X is a port-based authentication protocol,which provides a framework for the whole authentication process.In the authentication process,there are DoS attacks,man-in-the-middle attacks and other security issues,the problem of multiple devices share a user name password,there are some low efficiency problems such as multiple devices share a user name password problem and the higher authentication load.In this paper,these issues are optimized and improved.The specific improvement measures are as follows: to improve the authentication protocol and authentication mechanism between the client and the authentication system AP,and to bind the MAC address to enhance the system stability and anti attack ability.On the client side,USBKey technology is used to improve the key management and reduce the server load.In the authentication method,the double authentication method is adopted to make the whole authentication mechanism achieve a balance between security and efficiency.Based on the above solutions,the optimization design of mobile terminal security access control system,realizes the corresponding network model,and the safety and effectiveness of this system were tested,ultimately greatly enhance the safety performance of the access control system,but also greatly improve the system efficiency.
