摘　　要：无线传感器网络自身的特征,如网络规模庞大,动态的拓扑结构,有限的计算、通信和存储能力等,使得传统的密钥分配和管理机制无法直接应用。基于汉明距离提出了一种新的适用于无线传感器网络的密钥预分配方案。该方案将对称密钥系统和非对称密钥系统结合起来,并借助汉明距离的概念在无线传感器网络中实现了密钥的分配和管理。与随机密钥预分配方案相比,本方案在健壮性和安全性方面具有一定的优势,其计算和存储开销也不大,具有一定的实用性。Providing a suitable key establishment scheme in wireless sensor networks is challenging due to all the characteristics of these networks, such as dynamically changing topology and limitations of power, computation capability and storage resources. This paper presented a key pre-distribution scheme using Hamming distance which was suitable for wireless sensor networks. In this scheme, Hamming distance, asymmetric and symmetric cryptography were employed to achieve key pre-distribution and exchange in wireless sensor networks. The proposed key predistribution scheme has advantages over random key predistribution scheme in its security and only spends moderate computation cost, so it is quite practical.
