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。在该算法中,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,与已有基于随机方法的传感器网络对偶密钥建立算法相比,新算法具有更好的直接和间接对偶密钥建立概率。

Abstract: Based on the key pre-distribution scheme, a new pair-wise key establishment method was proposed for sensor networks, in which each node was pre-assigned with an initial global key before deployment. And after deployment, the node can dynamically establish different one-hop pair-wise key on the basis of the pre-assigned global initial key. The theoretical analysis and simulation results show that the new algorithm has better probability of direct and indirect pair-wise key establishment than the traditional random pair-wise key establishing scheme for sensor networks.
