无线分布式网络认证及密钥协商机制研究

无线分布式网络的路由机制已经相当成熟，但无线的开放性、自组织网络拓扑的不确定性以及无线设备资源的有限性为其安全性带来了一定挑战。本文针对无线自组织网络的这些特点，提出了一种安全的无线分布式网络模型SAM-DN，引入了分布式认证中心进行密钥协商。并采用ECC 代替了传统的RSA加密算法。这些新机制配合SAM-DN 自身的特点，使得该模型能更好适应无线分布式网络带宽、计算能力及存储空间的有限资源。

Research on Authentication and Key Agreement for Wireless Distributed Network
Lu Hai-feng1，Huang Ben-xiong2，Mo Yi-jun3 （Department of Electronic and Information, Huazhong University of Science and Technology, Wuhan 430074, China） Abstract: The route mechanism of wireless distributed network has developed maturely, but the security is still unsolved due to the openness, mobility and resource limitation. This paper gives out a security wireless distributed network model which is called SAM-DN, introduces distribute certification authority to intermediate key agreement, and uses ECC to take instead of traditional RSA encryption arithmetic. All above novel mechanisms make the SAM-DN adapt well to the limited bandwidth, computation capacity and storage.
