Practical Considerations on Quantum Key Distribution (QKD)

2013 International Conference on Advanced Computer Science Applications and Technologies, 2013
The advancement of the quantum computing is challenging the foundation of the cryptography by its almost unlimited computation power to predict the secure key that is thought to be absolutely secure based on the currently used algorithms such as the RSA and the Diffie-Hellman and others.

Quantum Key Distribution (QKD) Protocols: A Survey

2018 4th International Conference on Wireless and Telematics (ICWT), 2018
The security strength of key distribution of most conventional cryptography is relied on mathematical complexity and the irrational time needed to break the algorithm. But it will be ineffective if the secret key distribution procedure is weak. In 1994 Peter Shor proposed an algorithm that can factorize great integer number efficiently by using ...

Quantum key pool construction and key distribution scheme in multi-domain QKD optical networks (QKD-ON)

4th Optics Young Scientist Summit (OYSS 2020), 2021
In this paper, we propose a multi-domain quantum key pool (QKP) capacity adaptive supplement scheme based on balance between key resource and routing hop in multi-domain QKD-ON, and we conduct the simulation and evaluate the performance of the proposed scheme in terms of service blocking probability and utilization of key resource.

Turbo codes for quantum key distribution (QKD) applications

Proceedings of the 4th International Symposium on Applied Sciences in Biomedical and Communication Technologies, 2011
This paper investigates further on Quantum Key Distribution (QKD) protocols based on classical error-correcting codes, previously proposed by the authors. In [1], the classic channel coding techniques were shown to be suitable, in particular conditions, instead of quantum error-correcting codes, for correcting errors that occur during the exchange of a

Fragmentation-Based Quantum Key Distribution (QKD) in WDM Networks

2019 24th OptoElectronics and Communications Conference (OECC) and 2019 International Conference on Photonics in Switching and Computing (PSC), 2019
To integrate QKD with WDM networks without affecting the provisioning of classical service requests, we propose a wavelength fragmentation assignment scheme for QKD devices, which uses Tabu search to get satisfied secure key rate.
