Quantum key distribution in partially-trusted QKD ring networks
2020 IEEE 3rd International Conference on Information Systems and Computer Aided Education (ICISCAE), 2020The 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

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), 2019To 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.

Multicast network security using quantum key distribution (QKD)
2012 International Conference on Computer and Communication Engineering (ICCCE), 2012We 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 ...

Protection Schemes for Key Service in Optical Networks Secured by Quantum Key Distribution (QKD)
Journal of Optical Communications and Networking, 2019Quantum 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

Software defined optical networks secured by quantum key distribution (QKD)
2017 IEEE/CIC International Conference on Communications in China (ICCC), 2017Optical 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 ...
