Cost-Efficient Quantum Key Distribution (QKD) Over WDM Networks
Journal of Optical Communications and Networking, 2019Quantum key distribution (QKD) uses the laws of quantum mechanics to distribute secret keys with information-theoretic security. To realize QKD for secure communications among multiple distant users, fiber-based QKD networks can be deployed with today's available technologies.

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 ...

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 ...

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.

A Survey of Quantum Key Distribution (QKD) Network Simulation Platforms
2021 2nd Global Conference for Advancement in Technology (GCAT), 2021The 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 ...
