摘　　要：基于密钥预置技术,提出了一种新的传感器网络动态对偶密钥建立算法。该算法中节点在部署前首先被预置一个全局初始密钥;在部署之后,邻节点之间将基于预置的全局初始密钥来动态生成一跳的对偶密钥。理论分析与实验结果表明,由于该算法是完全分布式的,且节点间的对偶密钥是在节点部署之后动态生成,能保障节点间具有很高的直接和间接对偶密钥建立概率,更有效保障传感器网络的通信安全。Based on the new reputation model with a kind of key pre-distribution scheme,a novel dynamic pair-wise key establishment algorithm was presented.Each node was pre-assigned only one initial global key before deployment and the nodes were allowed to dynamically establish different 1-hop local pair-wise key with its different neighbour after deployment.Theoretical analysis and simulation results show that the new algorithm has a higher probability of direct and indirect pair-wise key establishment and can help ensure communication safety of sensor networks.
