摘要
对偶密钥技术的采用使无线传感器网络通信的安全性得到保障。对偶密钥中的动态密钥路径的应用又进一步提高无线传感器网络通信的可靠性。利用层次超立方体模型中节点编码的特性及其高容错性,提出了基于局部弱连通性概念的簇内动态密钥路径和基于位置信息的簇间动态密钥路径的两类算法。理论与计算机仿真数据分析表明,该算法具有良好的可靠性和高效性,是一种适合无线传感器网络安全可靠的具有实用价值的算法。
Security schemes of pair wise key establishment ensure communication security in wireless sensor networks. Dynamic key-path in pair wise key establishment farther increases communication security in the networks. Establishing scheme and algorithm for dynamic key-path in pair wise key for wireless sensor networks were presented based on the encoding peculiarity and high fault-tolerant ability of named H（k,u,m,v,n） （hierarchical hypercube） of cluster distributed sensor networks. Theoretic studies and figures of computer simulation show that the algorithm has good reliability performance and high efficiency, which is suitable for cluster distributed sensor networks.
