Asymptotic Analysis on Spatial Coupling Coding for Two-Way Relay Channels

, 2018
Compute-and-forward relaying is effective to increase bandwidth efficiency of wireless two-way relay channels. In a compute-and-forward scheme, a relay tries to decode a linear combination composed of transmitted messages from other terminals or relays ...

A Secure Data Aggregation Scheme to Traceback Malicious Charging Piles for Large‐Scale V2G Data‐Sharing Scenarios

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.

Secure communication via untrusted switchable decode-and-forward relay

2017 13th International Wireless Communications and Mobile Computing Conference (IWCMC), 2017
In this paper, a practical power efficient technique is proposed for an untrusted decode-and-forward (DAF) based cooperative communication system to provide secure communication between the source and the destination. More specifically, a DAF relay, called switchable DAF (sDAF), is designed in such a way that it can be switched to amplify-and-forward ...

Cooperative Interference and Power Allocation in a Bidirectional Untrusted Relay Network With Channel Estimation Errors

IEEE Access, 2018
The secure communication of a two-way untrusted amplify-and-forward relay network under the imperfect channel state information is investigated. To improve the secrecy of the relay wiretap system, artificial noise is introduced into each source signal ...
