基于分簇的WSN多项式随机密钥管理方案

The WSN polynornial random key management scheme based on cluster

结合多项式的密钥预分配方案和基于分簇管理的随机预分配方案,提出了一种改进的密钥管理方案,并在该方案中添加距离参数来提高无线传感器网络的安全性。对该方案的分析和评估结果表明,该方案提高了无线传感器网络的安全性,并能降低节点的存储空间和计算开销。

An improved key management scheme is proposed by combining the polynomial key pre-distribution scheme and cluster-based random pre-distribution scheme, and adding the distance parameter into the scheme to increase the secunity of WSN. Through assessment and analysis of the scheme, it indicates that the secheme increases the security of WSN and is able to reduce storage space and computational overhead.
