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。

Abstract: 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.
