Phase Noise in Real‐World Twin‐Field Quantum Key Distribution
Advanced Quantum Technologies, Volume 7, Issue 6, June 2024.This study explores the impact of various noise sources on twin‐field quantum key distribution (TF‐QKD) systems, focusing on phase noise from photon sources and fibers. Results show that different TF‐QKD protocols are similarly affected by phase noise.

Advanced Quantum Technologies, Volume 7, Issue 4, April 2024.Quantum communication is limited due to the need to generate single photon states and the transmission of these over long distances. The design and space‐qualification of a single photon source compatible with nanosatellites in the QUICK3 mission are presented.

A research on cross‐chain and interoperation methods of fusion protocol
IET Blockchain, Volume 4, Issue 1, Page 18-29, March 2024.Abstract At present, cross‐chain technology and cross‐chain system pay more attention to cross‐chain security and performance, and have shown great improvement in security, scalability and efficiency. However, the generality of cross‐chain technology in different scenarios is poor, and it may not fit in different business fields.

Physical Layer Security in an Untrusted Energy Harvesting Relay Network
IEEE Access, 2019 The security performance in an amplify-and-forward dual-hop untrusted relay network is considered. It is assumed that the source and multiple destinations are equipped with multiple antennas, and the information transmission is aided by a single-antenna ...

Machine Learning-Based Antenna Selection in Untrusted Relay Networks [PDF]
, 2019 This paper studies the transmit antenna selection based on machine learning (ML) schemes in untrusted relay networks. First, we state the conventional antenna selection scheme. Then, we implement three ML schemes, namely, the support vector machine-based scheme, the naive-Bayes-based scheme, and the k-nearest neighbors-based scheme, which are applied ...

Secrecy Rate-Optimum Energy Splitting for an Untrusted and Energy Harvesting Relay Network
IEEE Access, 2018 In this paper, a destination-assisted-jamming-based secure transmission is devised for an untrusted and energy harvesting relay network. In the proposed scheme, both source and destination split their energies into two parts for energy harvesting at the ...

Security–reliability tradeoff analysis of untrusted energy harvesting relay networks
International Journal of Distributed Sensor Networks, 2018 We investigate secure communications in untrusted energy harvesting relay networks, where the amplify-and-forward relay is an energy constrained node powered by the received radio frequency signals, and try to unauthorizedly decode the confidential ...
