Ad hoc网络密钥预配置方案

为了减少Ad hoc网络密钥管理方案对网络资源、节点资源的依赖,同时提高网络的安全性能,该文深入研究了传感器网络中基于多项式的密钥对预配置方案,将门限机制引用到密钥的传输过程当中,设计出一个应用于Ad hoc网络的高效密钥预配置方案:基于门限机制的密钥预配置方案。通过分析可以看出该方案有一些优良的特性,包括两节点间能以很高的概率成功建立密钥对、对入侵有较强的鲁棒性、高连通性、低通讯量。

Threshold-Based Key Predistribution in Ad hoc Network

To cut down the dependent of key management scheme on resource of networks, this paper deeply researches polynomial-based key predistribution in distribution sensor networks for reference and presents an efficient key predistribution scheme for Ad hoe networks, a threshold-based key predistribution scheme. The analysis in this paper indicates that this scheme has a number of good properties, such as high probability to establish pairwise keys, tolerance of node captures, and low communication overhead.
