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 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 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 …

In this paper, we study the benefits of full-duplex (FD) receiver jamming in enhancing the
physical-layer security of a two-tier decentralized wireless network with each tier deployed …

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 …

In this paper, we consider the problem of secure communications for a four-node system
consisting of one source, one destination, one eavesdropper, and one helper. We …

We analyze and optimize the secrecy performance of artificial noise (AN) in multi-input
single-output wiretap channels with multiple antennas at the transmitter and a single …

This paper investigates secrecy rate optimization problems for a multiple-input-single-output
(MISO) secrecy channel in the presence of multiple multiantenna eavesdroppers …

This paper studies the secrecy rate maximization problem of a secure wireless
communication system in the presence of multiple eavesdroppers. The security of the …

This paper studies physical layer security in a wireless ad hoc network with numerous
legitimate transmitter-receiver pairs and eavesdroppers. A hybrid full-duplex (FD)/half …
