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

Quantum key distribution in partially-trusted QKD ring networks

2020 IEEE 3rd International Conference on Information Systems and Computer Aided Education (ICISCAE), 2020
The long-distance transmission of quantum secret key is a challenge for quantum communication. As far as the current relay technology is concerned, the trusted relay technology is a more practical scheme. However, the trusted relay technology requires every relay node to be trusted, but in practical applications, the security of some relay nodes cannot

A Survey of Quantum Key Distribution (QKD) Network Simulation Platforms

2021 2nd Global Conference for Advancement in Technology (GCAT), 2021
The exponential development in Quantum Computing is becoming a threat to the existing asymmetric cryptographic algorithms like RSA (Rivest, Shamir, Adleman). A threat to these public key cryptographic algorithms is a threat to the entire Internet itself, as algorithms like RSA are the basic building blocks of existing secure Internet communication ...

Fiber scattering limitations for Quantum Key Distribution (QKD) system

Conference on Lasers and Electro-Optics/International Quantum Electronics Conference and Photonic Applications Systems Technologies, 2004
We characterized fiber scattering effects for quantum key distribution. Raman and Rayleigh scattering could be a limiting factor in system performance and should be considered in a QKD system ...

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.

Field demonstration of quantum key distribution in the Tokyo QKD Network

2011 International Quantum Electronics Conference (IQEC) and Conference on Lasers and Electro-Optics (CLEO) Pacific Rim incorporating the Australasian Conference on Optics, Lasers and Spectroscopy and the Australian Conference on Optical Fibre Technology, 2011
A secure communication network with novel quantum key distribution systems in a metropolitan area (very center of Tokyo) is reported. Different QKD schemes are integrated to demonstrate key relay for secure TV conferencing over a distance 45 km, stable long-term operation.

Quantum-Key Distribution (QKD) Fundamentals

2019
This chapter is devoted to QKD fundamentals. The chapter starts with description of key differences between conventional cryptography, classical physical-layer security (PLS), and QKD. In section on QKD basics, after historical overview, we review different QKD types and describe briefly common postprocessing steps, namely, information reconciliation ...

Vehicle-to-Vehicle Quantum Key Distribution (V2V-QKD)

CLEO 2024
Secure communication is required for future smart infrastructure networks. We demonstrate the first Quantum Key Distribution (QKD) link between two moving cars. Our system operates at low-speeds and at high-speeds on a U.S. Interstate Highway.

Quantum Key Distribution (QKD) Using Full Laguerre-Gauss Encoding

Imaging and Applied Optics 2018 (3D, AO, AIO, COSI, DH, IS, LACSEA, LS&C, MATH, pcAOP), 2018
We describe progress in developing a free-space QKD system that encodes information in both the radial and azimuthal degrees of freedom. Such a system makes optimum use of the sizes of sending and receiving telescopes.

Software defined optical networks secured by quantum key distribution (QKD)

2017 IEEE/CIC International Conference on Communications in China (ICCC), 2017
Optical network security is attracting increasing research interest. Currently, software defined optical network (SDON) has been proposed to increase network intelligence, which is gradually moving towards industrialization. However, new threats are emerging, e.g., control messages transferred via the control channels are vulnerable to eavesdropping ...
