This paper investigates cooperative security in wireless networks, where a source (Alice)
intends to transmit a confidential message to a legitimate destination (Bob), with the help of …

We propose a robust resource allocation framework to provide physical layer security for a
multiple input single output (MISO) communication system. In the considered system, we …

This paper studies a secure communication over multiple-input multiple-output multi-
antenna eavesdropper (MIMOME) channels which consist of legitimate parities, namely a …

Wireless physical-layer security is an emerging field of research aiming at preventing
eavesdropping in an open wireless medium. In this paper, we propose a novel waveform …

To enhance secure communications, we deploy the dual-polarized antenna arrays at
communication nodes of the multi-input multioutput (MIMO) system, where the base station …

The availability of multiple antennas in multiuser networks is akin to a double-edged sword
from the security point of view: the enhanced transmission quality of the legitimate users is …

Under both long (infinite) and short (finite) blocklength transmissions, this paper considers
physical layer security for a wireless interference network of multiple transmitter-user pairs …

In this paper, we study different secrecy rate optimization techniques for a multiple-input–
multiple-output (MIMO) secrecy channel, where a multiantenna cooperative jammer is …

This paper studies the achievable secrecy performance of multiple-input multiple-output
wiretap channels in the presence of imperfect channel state information (CSI) with practical …

This letter studies the practical design of secure transmissions without knowing the
eavesdropper's channel state information (ECSI). An ECSI-irrelevant metric is introduced to …
