基于分簇的有效无线传感器网络密钥管理方案

Efficient wireless sensor networks key management scheme based on the clustering

针对现有无线传感器网络密钥管理中计算量过大、存储空间过多和网络安全问题,在分簇结构无线传感器网络基础上,提出一种新的密钥管理方案,它通过将已存储的密钥部分地转化为即使被攻击者截获也无影响的特殊信息,来获取更加良好的安全性,同时又不降低网络的连通性。通过仿真与其他算法进行性能对比,结果显示这种方案具有更好的性能。

According to the existing problems in current key management strategy of wireless sensor network-overwhelming computational complexity,too much storage space and network security.Based on the clustering wireless sensor networks,a new scheme is proposed,it transforms partial keys stored in the sensors into the information which are useless for the attackers.This scheme could gain better security performance while remaining network connectivity unchanged.Through the simulation to compare with other algorithms,the results show that this scheme has better performance.
