We investigate the secrecy rate optimization problem in a wiretap channel with a single-
antenna source, a single-antenna eavesdropper, and a multiple-antenna full-duplex (FD) …

We propose a robust resource allocation framework to improve the physical layer security in
the presence of an active eavesdropper. In the considered system, we assume that both …

As many security solutions integrated with various technologies have been proposed
against eavesdropping attacks, technical advances for adversaries can also pose a serious …

This paper studies secrecy rate optimization in a wireless network with a single-antenna
source, a multi-antenna destination and a multi-antenna eavesdropper. This is an …

We propose a secure transmission scheme for a wiretap channel, where a source transmits
to a legitimate destination in the presence of a full-duplex eavesdropper. We assume that …

In this paper, we investigate the physical layer security of a full-duplex base station (BS)-
aided system in the worst case, where an uplink transmitter (UT) and a downlink receiver …

Security is an issue of paramount importance, yet is it a significant challenge for wireless
communications, which becomes more intricate when facing a full duplex (FD) active …

This paper considers the physical-layer secrecy design for full-duplex (FD) bidirectional
communications in the presence of an eavesdropper (Eve). The goal of this work is to …

We propose an antenna switching scheme in the full-duplex wiretap channel where the
legitimate receiver, equipped with two antennas, operates in a full-duplex mode. We focus …

In this paper, we investigate the secrecy performance of full-duplex multi-antenna spectrum-
sharing wiretap networks in which a jamming signal is simultaneously transmitted by the full …
