摘　　要：无线传感器网络由大量随机分布的传感器节点组成,这些节点在各自的环境进行信息采集、数据处理,并将信息传输至数据终端。文章提出了一个健壮的、可证明安全的可认证群密钥协商协议,该协议满足实用性、简单性和强安全性的要求。本文提出的可认证群密钥协商协议是基于椭圆曲线、双线性映射和Burmester和Desmedt协议实现。该协议通过两轮广播完成群会话密钥协商,比以前可认证群密钥协商协议需要更低的计算和通信开销。Wireless sensor network is composed of a large number of randomly distributed sensor nodes,which collect and pro cess information in their own environment and transmit information to data terminals.This paper proposes a robust,provably se cure,authenticable group key negotiation protocol,which meets the requirements of practicability,simplicity and strong security.The authenticable group key negotiation protocol proposed in this paper is based on elliptic curve,bilinear mapping and Burme ster and Desmedt protocols.The protocol achieves group session key negotiation through two rounds of broadcast and requires lower computation and communication overhead than previous authenticable group key negotiation protocols.
