Quantum Network Infrastructure
Advanced Quantum Technologies, Volume 8, Issue 2, February 2025.Quantum computing presents a threat to secure communication. Consequently, novel methods are investigated to address this global challenge, namely post quantum cryptography (PQC) and quantum key distribution (QKD). The image represents the distribution of a wavefunction over the entire world by using satellites in orbit.

Near-Optimal Modulo-and-Forward Scheme for the Untrusted Relay Channel
, 2015 This paper studies an untrusted relay channel, in which the destination sends artificial noise simultaneously with the source sending a message to the relay, in order to protect the source's confidential message.

Secure communications with untrusted relays: a multi‐pair two‐way relaying approach
IET Communications, 2018 Physical‐layer security is usually ensured by the injection of artificial noise (AN) at the legitimate source or destination when relays are cooperative but untrusted. In this work, in order to avoid the power‐consuming AN at the legitimate user pairs, the authors investigate multi‐pair two‐way relaying as a solution for secure transmission in wireless

IET Smart Grid, Volume 8, Issue 1, January/December 2025.This study tackles the critical issue of securing data transmission from charging piles in vehicle‐to‐grid (V2G) systems, where false data injection attacks can compromise user privacy and system integrity. We propose a novel data aggregation scheme that combines group‐based anomaly detection with elliptic curve cryptography.
