摘　　要：针对无线传感器网络(WSN)节点存储空间有限等特点,提出一种基于网格模型的无线传感器密钥管理的增强方案。该方案构造了一种新的密钥池密钥分配方案,提高了本地连接概率;同时利用哈希函数的不可逆性保护节点存储的密钥信息,使得安全性提高了一倍。与Du方案和E-G方案对比表明:该方案有较好的本地连接概率和安全性。Concerning the nodes＇ limited storage in the wireless sensor networks,an enhanced key distribution scheme based on grid was proposed for wireless sensor networks.The paper constructed a new key distribution scheme for key pools and improved the probability of local connectivity.At the same time,the scheme＇s security was doubly increased by the use of a hash function to protect key information stored in the nodes.Compared with Du＇s and E-G＇s schemes,this experimental result shows that the proposed scheme has better performance on the local connectivity probability and security.
