Securing Full-Duplex Amplify-and-Forward Relay-Aided Transmissions Through Processing-Time Optimization
Mohamed Marzban, Ahmed El Shafie, Ahmed Sultan +1
We investigate physical-layer security of the full-duplex (FD) amplify-and-forward (AF) relay channel. We provide a new perspective on the problem and show that the processing time…
Securing OFDM-Based NOMA SWIPT Systems
Ahmed Badawy, Ahmed El Shafie
In this paper, we present a physical-layer security scheme that exploits artificial noise (AN) to secure the downlink legitimate communications and transfer energy to nodes operati…
A Hybrid Artificial-Noise and Secret-Key Scheme for Securing OFDM Transmissions in V2G Networks
Ahmed El Shafie, Mohamed F. Marzban, Rakan Chabaan +1
We propose a new scheme to enhance the physical-layer security of wireless single-input single-output orthogonal-frequency division-multiplexing (OFDM) transmissions from an electr…
Secure Beamforming in Full-Duplex SWIPT Systems With Loopback Self-Interference Cancellation
Yanjie Dong, Ahmed El Shafie, Md. Jahangir Hossain +3
Security is a critical issue in full duplex (FD) communication systems due to the broadcast nature of wireless channels. In this paper, joint design of information and artificial n…
On the Monetary Loss Due to Passive and Active Attacks on MIMO Smart Grid Communications
Ahmed El Shafie, Hamadi Chihaoui, Ridha Hamila +3
We consider multiple source nodes (consumers) communicating wirelessly their energy demands to the meter data-management system (MDMS) over the subarea gateway(s). We quantify the…
An Artificial-Noise-Aided Secure Scheme for Hybrid Parallel PLC/Wireless OFDM Systems
Ahmed El Shafie, Mohamed F. Marzban, Rakan Chabaan +1
We investigate the physical-layer security of indoor hybrid parallel power-line/wireless orthogonal-frequency division-multiplexing (OFDM) communication systems. We propose an arti…
