摘要
无线传感器网络是由大量资源有限的传感器节点组成。为了保证传感器节点间的安全通信,找到一种有效的密钥管理方式是十分重要的。针对无线传感器节点能量低,存储空间有限的特点,提出了一种改进的密钥管理方案。该方案采用或运算及异或运算生成共享密钥对,计算量小、耗能低,并且密钥可更新。最后通过对比分析,该方案比其他方案具有更强的安全性和更低的能量消耗。
Wireless sensor network was composed by large amount of sensor peers with limited resource.It was very important to find an efficient method of secret key management to guarantee secure communication between sensors.According to the limited energy and low memory space of wireless sensors,one improved cluster-based key management protocol was proposed.This scheme establish pairwise keys through OR and XOR operations,these operationse were very efficient and consuming less energy of sensors,and the key could be updated.At last,this scheme has better performances in safe performance and energy cost than other schemes is proved through comparative analysis.
