一种基于分簇结构的Ad Hoc密钥管理方案

Ad Hoc网络是一种新型的无线、多跳、无中心分布式控制网络,它无需网络基础设施,具有很强的自组织性、鲁棒性、抗毁性和易构建等特点,其安全性研究正成为一个热点。文中对基于分簇结构的自组网进行了安全分析,并提出了一种新的密钥管理方案,与以前的方案相比,它不依赖于任何网络中心,有效地解决了单点失败问题,并引入了Diffie-Hellman算法,有效地提高了Ad Hoc网络的安全性。

A New Cluster-based Key Management Scheme in Ad Hoe Network

Ad Hoe is a new type of wireless, multi hop, no-centre and distributed control network. It needs no network infrastructures and has the features of strong self-organization, robustness, survivability and easy construction, and its security has become a research focus in recent years. In this paper, the security of cluster-based Ad hoc network is analyzed and a new key management scheme proposed. As compared with the previous schemes, it relies on no network-centre and effectively solves the problem of single-point failure. Also into it is the Diffie-Hellman algorithm and the security of Ad Hoc network is improved greatly.
