摘要
分析了点对点量子密钥分配协议的特点,在此基础上仿真研究了不同用户数量下量子-经典混合光网络量子密钥分配协议的网络性能,同时对比了三类协议的网络部署成本。仿真结果表明,对于中小型接入网(仿真用户数为32),制备-测量协议密钥生成率最高,安全传输距离最短,纠缠光协议密钥生成率最低,安全传输距离最长;对于较大规模网络,测量设备无关协议的网络部署成本最小,是建立混合光网络的最优选择。
Abstract
Quantum key distribution (QKD) networks are designed to allow multi-users for a dynamically anyto-any security communication. In this paper, three quantum key distribution schemes, compatible with classical optical networks, for future HQC networks are proposed and compared. For small-to-moderate size network, the highest secret key generation rate is supported by the prepare-measure scheme and the longest security distance is offered by entanglement-based scheme. For large networks, measurement-deviceindependent QKD, which is less demanding end-user technology and offers the best key rate, is the most proper solution for a cost-effective and reliable network deployment.
