| Summary: | 碩士 === 國立交通大學 === 資訊工程系所 === 93 === This thesis base on the mobility of wireless network, and the restriction of wired network, we combine wireless ad hoc network, wireless mesh network (WMN), and wired network to generate a new architecture. This thesis solve the problem of wireless devices signals decay with the distance, and provide a secure authentication way.
We use fixed node of WMN to help other movable nodes exchange information with AAA servers to do authentication, authorization, and accounting. In order to save the packet transferring on wireless network, we distributed AAA servers on WMN. Using (n,k) threshold secret sharing to do separate private key, and proactive secret sharing to update it. Moreover, this may avoid being attack. After mobile nodes authenticated, AAA servers issue a short-lived certificate for it to access services or communicate with other mobile nodes. Finally, we compare the advantage and disadvantage with distributed and centralized AAA server on WMN.
