摘　　要：针对Echenauer和Gligor的随机密钥预分配方案中存在的不足,提出一种把密钥池中的密钥分为不同的安全级别的密钥预分配方案。该方案利用Hash函数的单向运算特性,使安全等级高的密钥不会泄露出安全等级低的密钥信息,而节点间通信密钥的建立不受影响。分析表明,与现有的密钥预分配方案相比,该方案的通信开销、存储开销和计算开销变化小,安全性能高,适合在无线传感器网络中使用。In light of the defects of Eehenaue and Gligor probabilistic key pre-distribution scheme, we present a key pre-distribution scheme which divides the keys in key pool into different safety grade. The scheme uses the one-way computation property of Hash function to enable the keys with higher safety grade having no possibility in disclosing the key information with lower safety grade, while the establishment of communication keys between the nodes is not affected. Analysis shows that compared with existing key pre-distribution scheme, this one has less changes in overheads of communication, storage and computation, has high safety, and is suitable for application in wireless sensor networks.
