In these days, the Mobile Ad hoc NETwork (MANET) technology spreads widely. Architecture and security issue is the most sensitive challenge of MANET. MANET support to nodes for directly communications with all the other nodes within their radio ranges through multiple wireless links, where the nodes are not in the direct communication range using intermediate node(s) to communicate with each other. In a MANET, the users' mobile devices behave as a network, and they must cooperatively provide the different functions which are generally provided by the network infrastructure like as routers, switches, servers. The security issues and requirement of the MANET depends on its application. Specific security architecture is necessary for specific application.
