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…
Secret-Key-Aided Scheme for Securing Untrusted DF Relaying Networks
Ahmed El Shafie, Ahmed Sultan, Asma Mabrouk +2
This paper proposes a new scheme to secure the transmissions in an untrusted decode-and-forward (DF) relaying network. A legitimate source node, Alice, sends her data to a legitima…
