Evaluation of a switched - QKD network performance compared to a relayed - QKD network
Summary:
Quantum Key Distribution has recently dominated the field of optical communications cryptography. This thesis analyzes Quantum Key Distribution and delves into the possibilities offered by the implementation of a Switched-QKD network by comparing it with a Relayd-QKD network. The introduction surveys the principles of quantum mechanics and the techniques applied to the implementation and study of quantum key distribution. Then two experimental structures of a Switched-QKD network and a Point-to-Point QKD network are presented, in order to analyze the possibilities offered by the Switched-QKD architecture in high-speed networks. Furthermore, a fully-managed, field-deployed, three-node Hybrid Relayed-QKD ring network with L1-OTNsec encryption is presented, integrating the KMS and the application layer. Finally, it concludes with a comparison of the two Switched-QKD and Relayed-QKD architectures, based on the use cases of each of them and the challenges that characterize them.
