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

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 …

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 …

The issues of the physical layer security are studied, where one transmitter (Alice), one full‐
duplex (FD) legitimate receiver (Bob) and one multi‐antenna jammer (Charlie) are …

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 …

In this paper, we investigate the performance of artificial noise assisted secure
communication in the presence of a full-duplex active eavesdropper who can …

Full-duplex (FD) jamming transceivers recently have been shown to enhance the
information security of wireless communication systems by simultaneously transmitting …

With the emergence of physical layer security, there has been an increasing interest toward
its framework comprising a wiretap channel with a transmitter, a receiver, and an …

To reduce the secrecy loss due to the correlation between main and wiretap channels, this
paper introduces a cooperative jamming relay to degrade the reception at the eavesdropper …

In this paper, we introduce smart jamming attack by an active eavesdropper (or jammer) who
is capable of full-duplex communications. Using self-interference cancellation, the active …
