传感器网络随机密钥对模型密钥管理方案改进

Key Management Scheme Based on Pairewise Key in WSNs

在传感器网络中有必要应用加密技术对节点间的通信进行保护。基于随机密钥对模型的传感器网络的密钥管理方案(BPKP),实现了包括初始密钥对向量预分配,通信密钥对向量的建立和通信密钥对向量更新。对BPKP的性能分析表明:BPKP具有高网络连通性、高安全性和低耗能的优点。

WSNs require cryptographic protection of communications between sensor nodes. BPKP based on Pairwise Key Pre-distribution key management scheme has implemented such functions as initial key-pair vectors distribution, the construction of communication key-pair vectors, and communication key-pair vectors updating. Simulation, analysis comparison with other pre-distribution scheme indicate that the BPKP scheme has dramatic advantage in network connectivity, security and energy consumption.
