摘要
由于ADHOC网络是一种特殊的无线网络,其路由安全性显得尤为重要。文中深入研究了ADHOC网络中安全路由协议sead,对其中的哈希链保护机制进行了深入的分析,包括哈希链中链值的传播,哈希链值在节点间的验证机制。在对sead协议哈希链机制深入分析的基础上,发现其重新生成新链后所带来的哈希链过长以及其链值利用率低的问题,并提出了一个解决方案,节省了资源空间,提高了资源利用率。
As Ad Hoc network is aspecial wireless networks, this routing security seems to be quite important. This paper deeply studies sead protocol designed for Ad hoc networks, and analyzes thoroughly its hash chain mechanism, including transmission and verification of hash chain elements between different mobile nodes. Based on the deep analysis of the hash chain mechanism, some problems are found, such as that the new hash chain is too long and the utilization rate of hash chain elemnts is too low after generating a new hash chain. Thus a solution to the problems is given, which could save resources and improve the utilization rate.
