移动Ad-hoc网络安全

Security in Mobile Ad-hoc Networks

移动 Ad- hoc网络是一种不依赖任何固定的基础设施的新型的无线网络 .在网络中 ,节点之间的通信完全依赖无线链路 ,网络拓扑随着节点的移动频繁变化 .移动 Ad- hoc网络不同于有线网络的特性对于保证其安全性提出了新的挑战 .本文在探讨移动 Ad- hoc网络的安全需求的基础上 ,着重分析了移动 Ad- hoc网络易于遭受的攻击 ,并集中了讨论移动 Ad- hoc网络的路由安全。

In Ad-hoc networks the communicating nodes do not necessarily rely on a fixed infrastructure, which sets new challenges for the necessary security architecture they apply. In this paper, we study the security goals to be achieved and the threats mobile Ad-hoc network faces. We focus primarily on the routing security and key management on mobile Ad-hoc network.
