摘　　要：现有商用化量子密钥分发(Quantum Key Distribution,QKD)系统的密钥生成速率较低,高速率等级通信业务难以采用“一次一密”加密,高昂的量子通信建网成本极大地限制了量子通信业务的推广。针对上述问题提出了一种基于点对点QKD系统的量子密码云服务平台的构建方案,包括QKD网络层、密钥管理层、应用服务层,可实现量子密钥的集中生成、统一管理以及多样化量子密码服务的提供。为保证平台的可用性,提出了云间经典密钥分发机制和量子密钥扩展算法,在一定程度上促进了量子保密通信的实用化进程。Currently,commercial Quantum Key Distribution(QKD)systems have a low key generation rate,High-speed communication services are difficult to use“one-time pad”encryption,the high cost of quantum communication network construction greatly limits the promotion of quantum communication services.This paper proposes a construction scheme of quantum cryptography cloud service platform based on point-to-point QKD system,which can realize the centralized generation and unified management of quantum keys and the provision of diversified quantum cryptographic services.To ensure the availability of the platform,the inter-cloud classical key distribution mechanism and quantum key extension mechanism are proposed.The research of this scheme has promoted the practical application of quantum secure communication to a certain extent.
