基于簇内分组的ECC密钥管理方案

A Key Management Scheme Using ECC with Grouping Cluster

根据椭圆曲线密码(Elliptic Curve Cryptography,简称ECC)体制,论文提出了一种逻辑簇内分组结构的无线传感器网络(Wireless Sensor Networks,简称WSN)的ECC密钥管理方案。方案将簇内节点逻辑划分成多个组,每个组共享不同的通信密钥,簇头实时掌握簇内每个组的通信密钥,簇内节点通过所在组的共享密钥与簇头通信,确保了通信的安全性。理论分析和仿真实验表明,本方案在保障密钥安全的前提下,有效地减少了密钥协商过程中的通信能量消耗,非常适合资源有限的大规模无线传感器网络。

Based on Elliptic Curve Cryptography（which is short for ECC） mechanism,propose an ECC key management scheme for a wireless sensor network which has a logical grouping structure within the cluster.This scheme divides the cluster into multiple logical groups,and each group shares different communication key.The cluster header controls every group＇s communication key in real time and the cluster members communicate with the cluster header through the group＇s sharing secret key they belonged to which can ensure the safety of communication.The theory analysis and simulation results show that this scheme effectively reduces communication power consumption during the process of negotiating secret key under the premise of ensuring key security,is very suitable for a large-scale wireless sensor network of limited resources.
