Abstract

This paper considers an application of the quantum stream cipher (QSC) Y-00. QSC Y-00 can provide secure long-haul and high-capacity data transmission in optical networks. Post-quantum cryptography (PQC) can provide quantum-resistant authentication and key-establishment. We propose a secure link architecture for optical communication networks using QSC Y-00 and PQC. Further, we report a field experiment using the optical fibers embedded along a railway truck between two train stations to demonstrate user authentication, key-establishment, and secure data communication with the intensity modulation-based Y-00 transceivers and PQC. Finally, we discuss the further applications of the proposed secure link architecture.
