Design And Implementation Of Security Encryption Module For Wmesh

Traditional Wireless LAN technology is one of the hotest technologiesin mobile and communications area, compared to the old copper twisted pair wired LAN, implementation of the wireless local area network and the start-up is relatively simple, cost of maintenance is cheap, and only need to set one or several access equipment to build a local area network cover the whole area or building. However, the wireless local area network system is not completely wireless system, its servers and backbone network is still placed in fixed network, no more than clients can through wireless way and establish a connection network.Wireless Mesh network is a kind of based on peer-to-peer network technology, jump routing the new network structure, a wireless Mesh network from the traditional peer-to-peer network development and change, it inherits a point of the excellent characteristics of network, such as dynamic expansion, AD hoc network, the configuration, the management and the healing, etc. As a wireless field a new technology, with its high transfer rate, high reliability, low cost and simple and quick network configuration and maintenance, in the next generation network has an important position, in many fields are in a wide range of applications.Since WLAN Mesh uses the air as a medium of communication, it is very vulnerable to attack.In that case security becomes an essential of the network.Security consists of securing medium with encryption algorithms and distribution and management of there keys.This paper first introduces wireless Mesh network related concepts and then to average cable network security the design and implement of briefly analyzed, and raises the wireless Mesh network security problems. Secondly, the paper to the wireless Mesh network security module of a detailed requirement analysis, the research to the wireless Mesh network security agreement and the related encryption algorithm, secondly, this article from the point of view of software development, design and realized wireless Mesh network security mechanism, And starting from the point of view of the key hierarchy as defined in the international standards, the implementation of the key technologies in the wireless mesh network security encryption module.
