Ad Hoc网络的安全策略

Security Strategy in Ad Hoc Networks

为了在恶劣的环境中在移动节点之间提供受保护的通信,安全问题已经越来越受到关注。移动Ad Hoc的特点为实现安全带来了一系列挑战,如:公开的对等网络结构、共享的无线资源和高度动态的网络拓扑等。主要着眼于在MANET网络中保护移动节点间的多跳网络连接这个基本安全问题。从这个问题入手提出了相应的安全方案。完整的安全解决方案必须包括全部的三个安全部分:防御攻击、检测入侵节点和对于攻击的反应。

Security has become a primary concern in telecommunication protection between mobile nodes in a hostile environment. The characteristics of mobile ad hoc networks, such as open peer-topeer network architecture, shared wireless resource and highly dynamic network topology, pose a number of challengers to the security design. In this paper we focus on the fundamental security problem of protecting the multihop network connectivity between mobile nodes in a MANET. We reach the conclusion that the complete security solution should span both layers, and encompass all three security components of prevention, detection, and reaction.
