摘要
在无线传感器网络中,如何以较小的计算量实现传感器之间的密钥分配一直是研究的热点。 提出了一种基于量子纠缠交换的密钥分配方案,对基于簇的层次型网络进行设计,通过广播和点对 点的通信分别实现基站与簇头、簇头与终端节点间的密钥分配。在基站进行纠缠粒子分发、实现纠 缠交换,簇头和终端节点仅需进行简单的测量操作。所提方案可有效减少各节点的计算量、存储空间 和能量消耗,提高整个无线传感网的性能。
Abstract
In wireless sensor network (WSN), how to realize key distribution among sensors with lower computational cost is always an interesting issue. A key distribution scheme based on quantum entanglement exchange is proposed. A hierarchical network based cluster is designed, and the key distribution among the base station and cluster head, cluster head and terminal nodes is realized by broadcast and peer-to-peer communications. The entangled particle distribution is carried out at the base station, and the entanglement exchange is realized. The cluster heads and terminal nodes require only simple measurement operation. The proposed scheme can effectively reduce the computation amount, storage and energy consumption of each node, and improve performance of the whole wireless sensor network.
