基于身份认证的安全量子中继器网络编码方案

摘要

This paper proposes a secure quantum repeater network coding scheme based on identity authentication by introducing quantum one-time pad into quantum repeater network.To defend against active attacks during encoding,quantum one-time pad is used for identity authentication of communication between any adjacent nodes,and coding algorithms are op-timized.Eventually,quantum entanglements which are generated between source nodes and target nodes work as channels and constitute a network of quantum teleportation.Scheme analyses show that it can realize high-reliability and high-security long-distance quantum communication.%本文将量子一次一密通信方法引入到量子中继器网络中，提出了基于身份认证的安全量子中继器网络编码方案。针对编码过程中存在的主动攻击问题，用一次一密的方式实现任意相邻节点通信过程中的身份认证，优化编码算法，最终在源节点与目的节点间生成量子纠缠态作为信道，构成量子隐形传态网络。方案分析表明，这种方案可以实现高可靠性、高安全性的远程量子通信。
