Abstract

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
