移动ad hoc网络是由移动节点自组织形成的网络
由于其动态拓扑、无线通信的特点
容易遭受各种安全威胁.该文介绍了移动ad hoc网络安全研究的最新研究进展.首先从传输信道、移动节点、动态拓扑、安全机制、路由协议几方面
分析了移动ad hoc网络的安全弱点
然后将移动ad hoc网络安全方面的研究分为三个方向:密钥分配与管理、入侵检测、增强合作.对每个方向内一些典型安全方案也进行了分类论述
同时分析了各种方案的优点和缺点
并进行了综合比较.文中阐明了目前协议存在的一些问题并提出了相应的改进方法
最后指出了下一步研究方向.
In resent years
mobile ad hoc networks are a new emerging field with its potential applications in extremely unpredictable and dynamic environments.However
it is particularly vulnerable due to its features of open medium
dynamic changing topology
cooperative routing algorithms.The article surveys the state of the art in security for mobile ad hoc networks.Firstly
we analyze various possible threats to security in mobile ad hoc networks.Secondly
we illustrate representative solutions to deal with those threats
including key management
intrusion detection and cooperation enforcement.We also make a comparison and discussion of their respective merits and faults
and propose some ways to fix these problems.Finally
we also present the challenges which are still worth to further research in the area.
