摘要： 针对经典随机密钥预分配方案在网络安全性、连通性和能耗方面存在的不足，提出一种基于区域划分的无线传感器网络(WSN)混沌密钥管理方案。使用划分网络区域的方法进行密钥更新，以减少节点存储开销，利用混沌的初值敏感性和遍历性增强通信的安全性。仿真结果表明，该方案可以在提高WSN连通性和安全性的同时，较大地降低节点存储和通信能耗。

Abstract: Aiming at the problems of network security, connectivity and large memory and communication costs in classic key pre-distribution scheme, this paper presents a Wireless Sensor Network(WSN) chaos key management scheme based on district-divided. It updates key by group partition method to reduce the network storage, and the ergodicity and initial value sensitivity of chaos are used to transmit safety information. Simulation results show that both the security and connectivity of WSN are improved, and memory cost and communication cost are reduced.
