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…
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…
Secure Beamforming in Full-Duplex SWIPT Systems
Yanjie Dong, Ahmed El Shafie, Md. Jahangir Hossain +3
Physical layer security is a key issue in the full duplex (FD) communication systems due to the broadcast nature of wireless channels. In this paper, the joint design of informatio…
Hybrid Spatio-Temporal Artificial Noise Design for Secure MIMOME-OFDM Systems
Ahmed El Shafie, Zhiguo Ding, Naofal Al-Dhahir
This paper investigates artificial noise injection into the temporal and spatial dimensions of a legitimate wireless communication system to secure its transmissions from potential…
