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 ...

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.

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.

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 ...

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 ...

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 ...

Elgamal Cryptographic Scheme Based on Quantum Key Distribution (QKD)

IAR Journal of Engineering and Technology, 2020
Key distribution is the strength of any cryptographic system as the security of any communication is totally depends on the secret key. Therefore, it is important to have secure key distribution system because if the key get compromised then whole system will get compromised.

Protection Schemes for Key Service in Optical Networks Secured by Quantum Key Distribution (QKD)

Journal of Optical Communications and Networking, 2019
Quantum key distribution (QKD) is considered a secure solution for key distribution and applied in optical networks to overcome security issues by providing key services in different lightpaths. In optical networks, lightpaths in fibers can be used for the delivery of QKD due to their good transmission performance. Accordingly, optical networks secured

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.

Multicast network security using quantum key distribution (QKD)

2012 International Conference on Computer and Communication Engineering (ICCCE), 2012
We reviewed the confidentiality and authentication for multi-party applications. A conceptual model of a secure multicast network has been presented by adding a quantum key distribution (QKD) network to its architecture. The model is divided into three phases, the first phase, QKD network generate secure keys to encrypt not only data but also ...
