| 摘 要： | 首先借鉴Leighton Micali协议中的多重单向散列建立密钥思想，设计了一种基本的多重单向散列密钥分配协议。该协议能确保所有邻居节点能建立安全链路，但是安全性能差。然后结合多重单向散列与随机密钥预分配，提出了多重单向散列随机密钥预分配协议，并详细分析了性能。与现有的协议相比，该协议只需很少的单向散列运算，计算负载小，安全性能高，非常适用于传感器网络。

| Abstract: | Firstly,a basic multiple one-way hash key distribution protocol was developed based on Leighton Micali protocol.It ensures that all neighbors' nodes can establish secure links,but has poor safety performance.Then a novel key distribution protocol integrating multiple one-way hash with random key pre-distribution was presented.Only one-way hash function is requirement for sensor node,which is very suitable for sensor networks.Compared with other protocols,this one has better performance,which need less computing overhead and can enhance the security. |
