Research On Security And Privacy Protection For WMN

The rapid development of wireless mobile communication technology has opened up bright prospects of applications for wireless networks. As a new type of w- ireless network, WMN has great potential for development. At the beginning of this century so far, WMN has become one of the hot topics in wireless mobile communications and network security academic circles. As the WMN's own multihop cascaded (multi-hop), self-organization, self-healing, wireless location, node self-management, intelligent edge, as well as mobile broadband and other features, and in order to enable them to better serve the human needs its various aspects must study in-depth, to provide a safe service, WMN is one of the hot research. WMN's characteristics make it have larger security threats than traditional wireless networks. Authentication and Key Agreement is one of the key issues that must be addressed in WMN. Only have an effective solution to the problems of authentication and key agreement, key management and secure routing protocols can be realized.In this dissertation, the anonymity, privacy protection and authentication protocols of WMN have been studied, the principal tasks of this paper include the following aspects:(1) According to the characteristics of WMN, based on Hash Function and Diffie-Hellman algorithm, I put forward an anonymous access authentication protocol ,it is suitable for vehicle Mesh networks, and analyze the protocol correctness, safety and feasibility.(2) A more powerful network simulation tool NS2 is studied, and we use it to conduct a network simulation in this dissertation.
