摘要
在无线传感器网络中,能量消耗主要集中在节点之间的通信上,节点计算所消耗的能量远小于通信所消耗的能量。由于无线传感器网络的"一对多"和"多对一"通信模式,广播是节约能量的主要通信方式。为了保证广播实体和消息的合法性和保密性,必须首先解决无线传感器网络广播密钥安全分发问题。本文在充分考虑无线传感器网络自身特点的基础上,基于Shamir的门限秘密共享方案,提出了椭圆曲线双线性对上的无线传感器网络广播密钥分发协议,并对其进行安全性和性能分析。分析发现,该协议不仅满足安全性要求,同时,能够适合无线传感器网络的特殊应用要求。
In wireless sensor networks, the most energy-consuming operation is the communication among network nodes. The energy consumed in communication is much less than that in computation. The broadcasting is one of the most energy-saving forms in communication because of the communication modes of One-To-Many and Many-To-One. To assure the validity of the entity and the privacy of the message, we should firstly solve the problem of the broadcast key secure distribution. Motivated by these concerns, on the enough consideration on the characteristics of wireless sensor networks, a broadcast key secure distribution protocol is proposed, in which Shamir＇s threshold secret sharing scheme and the ellipse curve bilinear pair are adopted. Then, security analysis and performance analysis are made on it. Analyses show that this protocol can be used to guarantee the security of wireless sensor networks, and at the same time, it can meet the special application requirements of wireless sensor networks.
