一种新的大规模无线传感器网络安全引导模式

A New Security Bootstrap Scheme for Large Scale Wireless Sensor Networks

针对目前无线传感器网络中的安全引导技术的缺乏和不足,提出了一种新的无线传感器网络的安全引导模式。该模式充分利用了目前无线传感器网络部署中提出的分簇算法,并结合随机密钥预分布模型的优点。在合理利用传感器网络有限资源的情况下,减少了无线传感器网络中单个节点的密钥环长度,节约了节点资源,延长了网络生命周期。文中论述了该模式的构架,引导过程,并对该模式进行了仿真分析。

Considering the limitation and deficiency of security bootstrap on Wireless Sensor Networks （WSN）, a new security bootstrap scheme for WSN is proposed. The new scheme exploits the clustering algorithm of WSN deployment and the merit of random key pre-distribution. The new scheme can reasonably use the limited resources and reduce the length of key ring of single node in wireless sensor network; it also can save the energy of nodes and prolong the lifecycle of WSN. This paper describes the architecture and the security bootstrap of the new scheme, and analyzes the performance of the scheme.
