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 …

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 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 …

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

In this paper, we consider the physical layer security issue for the multi-channel full-duplex
(FD) communications in the presence of eavesdroppers. There co-exist multiple FD pairs …

This letter considers secrecy communication from an information-theoretic perspective, and
studies the secrecy capacity of a multi-input multi-output (MIMO) Gaussian wiretap channel …

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 …

Information security is of paramount importance yet significant challenge for wireless
communications. In this paper, we investigate the power-efficient transmissions with security …

Full-duplex communication enables simultaneous transmission from both ends of a
communication link, thereby promising significant performance gains. Generally, it has been …

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 …
