Broadcast Authentication Protocol Scheme Based on Layer-Cluster in WSN

认证机制是无线传感器网络安全机制关键技术之一。本文给出了无线传感器网络的层簇式结构,分析了无线传感器网络的广播认证协议。在此基础上提出一种基于分簇的广播认证机制N-μTESLA方案,设计了广播和组播认证协议。仿真结果表明所提出的方案与μTESLA方案相比,可以减少节点的能量消耗,使网络的生存周期延长。

The authentication protocol is one of the important technologies in the security mechanism of wireless sensor networks （WSN）. This paper provides a WSN layer-cluster structure and analyzes a WSN broadcast authentication protocol. On these bases, a new broadcast authentication protocol based on layer-cluster, called the N-μTESLA scheme is presented, and the broadcast and the group broadcast authentication protocol are designed. Compared with the μTESLA scheme, simulation results indicate that the scheme has better performance, thus it can reduce the node energy consumption and extend the life circle of the network.
