摘要:

依托量子密钥分发(Quantum Key Distribution,QKD)网络对量子设备产生的密钥进行网络分发,确保两地之间密钥分配的绝对安全,为光传送网(Optical Transport Network,OTN)用户提供加/解密密钥,实现OTN数据传输的安全可靠。以OTN网络为基础,量子加密赋能OTN为出发点,描述了OTN和QKD融合网络架构、设备部署、方案设计、实现过程;针对OTN量子加密网络的目标应用客户,提出匹配OTN网络应用的量子城域网相应的部署方案。

Abstract:

Relying on the Quantum Key Distribution (QKD) network to distribute the keys generated by quantum devices over the network, it ensures the absolute security of key distribution between two locations, providves encryption/decryption keys for optical transport network (OTN) users, and realizes the security and reliability of OTN data transmission. Based on the OTN network and starting from the empowerment of OTN by quantum encryption, this paper describes the architecture, device deployment, scheme design, and implementation process of the OTN and QKD converged network. For the target application customers of the OTN quantum encryption network, this paper proposes a deployment scheme corresponding to the quantum metropolitan area network that matches the OTN network application.

Key words: quantum key distribution, OTN quantum encryption network, converged network architecture
