Abstract


A great development has been happened in the WLAN from its birth to present, the technology of it has been maturing day by day. And relies on its conveniently, quick, inexpensive and so on, WLAN is widely utilized in the correspondence, the medical service, the entertainment and other domains. Although the applications of WLAN is getting more and more popular, the terminal high speed migration’s correspondence quality question, specially under the guarantee secure premise’s mobile communication question, is still a main problem which puzzles its further development.In this paper, based on the study and analysis of the existing secure technology and fast handover protocols in the WLAN, we proposed a new secure fast handover protocol named WSP-H. Attempt to solve the problem that mobile terminal safely and fast transition between different APs by reducing the delay of secure authentication.First of all, conceptions about WLAN are briefly introduced. What’s more, we proposed a new secure fast handover protocol based on the study and analysis of the existing secure technology and fast handover protocols. The access and fast handover process of WSP-H protocol is detailedly introduced in this paper. In addition, a secure fast handover system is designed and implemented integrated with open source software. The system consists of supplicant, AP and authentication server modules.Finally, an experiment platform is built, and the secure fast handover system is tested. The testing result shows that the WSP-H secure fast handover system attains the design goal, the secure fast handover protocol is well implemented on the system, and it reduces the handover delay.
