Abstract

In this work, we outline our recent developments of building experimental Quantum Key Distribution (QKD) network. The main focus is on the integration of QKD technologies into classical communication networks and assessing and exploiting the possibilities of how quantum technologies can complement existing cryptographic solutions. In particular: 1) we outline the conceptual architecture of the hybrid network developed by gradually adding individual QKD links to it; 2) describe a new protocol for delivering QKD-generated keys as a service; 3) describe the requirements for key management and user authentication in such hybrid networks and how these can be solved with the available technologies.

The developed protocol establishing QKD-keyed TLS connection uses Post Quantum Cryptography (PQC) algorithms for the secure delivery of QKD keys. It demonstrates how the strengths of QKD and PQC technologies can complement one another.

The work has been supported by the European Regional Development Fund project No. 1.1.1.1/20/A/106.
