Quantum Key Distribution Networks: Challenges and Future Research Issues in Security

Applied Sciences, 2021
A quantum key distribution (QKD) network is proposed to allow QKD protocols to be the infrastructure of the Internet for distributing unconditional security keys instead of existing public-key cryptography based on computationally complex mathematical ...

Security of device-independent quantum key distribution protocols: a review [PDF]

Quantum, 2023
Device-independent quantum key distribution (DI-QKD) is often seen as the ultimate key exchange protocol in terms of security, as it can be performed securely with uncharacterised black-box devices.

Software-Defined Networking Orchestration for Interoperable Key Management of Quantum Key Distribution Networks

Entropy, 2023
This paper demonstrates the use of software-defined networking (SDN) orchestration to integrate regionally separated networks in which different network parts use incompatible key management systems (KMSs) managed by different SDN controllers to ensure ...

State independent QKD

, 2023
We present an adaptive procedure for aligning quantum non-locality experiments without any knowledge of the two-qudit state shared by the participating parties. The quantum state produced by the source, its unitary evolution as well as the actual measurement bases remain unknown to both parties at all times.

Enabling Resilient Quantum-Secured Microgrids Through Software-Defined Networking

IEEE Transactions on Quantum Engineering, 2022
Quantum key distribution (QKD) has been considered a potent and mature approach to secure communication in the quantum era. However, there exist resilience gaps that hinder the practical usefulness of QKD.

The Case for Quantum Key Distribution [PDF]

, 2009
Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructures.

QKD: Recovering Unused Quantum Bits [PDF]

2008 3rd International Conference on Information and Communication Technologies: From Theory to Applications, 2008
Practical quantum key distribution gain is usually less than the theoretical limit, this is due to the imperfection of physical devices, quantum channels, and the lost qubits due to test carried out for for the identification of the presence of an eavesdropper and the consequence reduction of obtained knowledge.
