一种增强Ad hoc网络路由协议安全性的方案

A method for security enhancement in routing protocols of Ad hoc networks

移动AdHoc网络是一种新型的无线移动网络 ,由于它具有开放媒质、动态拓扑、分布式合作及受限的网络能力等特点 ,所以特别容易受到攻击 .在Adhoc网络中 ,一个节点不仅是一个主机 ,而且是一个路由器 ,它可以在网络中寻找和保持到其他节点的路由 .如果路由被误导 ,整个网络可能陷于瘫痪 .所以 ,路由安全是整个Adhoc网络的安全中最重要的一环 .论述了Adhoc网络几种路由协议 ,并针对Adhoc网络中AODV协议的黑洞攻击 ,提出了一种增强性的安全解决方案 。

As a new kind of wireless mobile network, mobile Ad hoc network(MANET) is characterized by open medium, dynamic topology, distributed cooperation and constrained capability, hence Ad hoc network is particularly vulnerable. A node in Ad hoc networks is not only a host but also a router, which can discover and maintain the routing information. If routing is misdirected, the whole network would have been paralysed. As a result, routing security is the most important factor in security of whole Ad hoc networks....
