| Summary: | 碩士 === 國立交通大學 === 電資學院學程碩士班 === 91 === With the progress of technique, wireless LAN (WLAN) provides wireless access beyond original wired connection. Simultaneously, cellular telecommunication network has extended much more data relative services (2.5G, 3G) from traditional voice service (1G, 2G). It becomes an urgent topic that how to integrate WLAN and current cellular network into a B3G (Beyond 3G) network.
In this thesis, we propose a WLAN inter-AP fast handover scheme. It relies on SIM-based and integrates authentication procedure, message integrity check, data privacy and pre-authentication four techniques together to eliminate re-authentication requirement during handover. With this scheme we can not only shorten the inter-AP handover delay but also provide an identical authentication mechanism for both WLAN and cellular network. The identical authentication mechanism makes the possibility of further inter system fast handover. Beyond the fast handover benefit, these four techniques integrated together eventually provide a watertightly secure WLAN environment. Only the security and convenience of public WLAN environment can make the goal that fast deploys public WLAN/cellular integrated networks for next B3G service.
