【摘要】 移动ad hoc网络是一种完全由移动主机构成的网络,其主要特点为网络拓扑易变,带宽、能源有限。这些特点使得适应于固定网络的安全策略在移动ad hoc网络上不能很好地发挥作用,需要设计一些针对其特点的解决方案.该文介绍了针对移动ad hoc网络路由协议安全方面的最新研究进展,首先介绍了移动ad hoc网络的安全弱点和攻击类型,其后时一些典型方案进行了说明,分析了各种方案的优点和缺点,并进行了综合比较。文中分析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。更多还原

【Abstract】 A mobile ad hoc network is a collection of mobile nodes that are dynamically and arbitrarily. It has several salient characteristics: dynamic topologies, bandwidth-constrained, variably capacity links, energy-constrained opera- tion, limited physical security. Due to these properties, mobile ad hoc networks present great challenges for research in security. The paper surveys the state of the art in secure routing protocol for mobile ad hoc networks. Firstly, we provide security threats applicable and attacks to mobile ad hoc networks. Secondly, we cover some representative so- lutions. We also provide a comparison and discussion of their respective merits and drawbacks, and propose some im- provements for these drawbacks. Finally, we outline future research directions.更多还原
