This paper studies the use of artificial interference in reducing the likelihood that a message
transmitted between two multi-antenna nodes is intercepted by an undetected …

This paper examines linear beamforming methods for secure communications in a multiuser
wiretap channel with a single transmitter, multiple legitimate receivers, and a single …

In this paper, we investigate methods for reducing the likelihood that a message transmitted
between two multi-antenna nodes is intercepted by an undetected eavesdropper. In …

Secrecy on the physical layer receives increased research interest. Especially in the
wireless communication scenarios, the interest in confidentiality of messages increases. In …

We study a multi-antenna wiretap channel, where the transmitter does not have perfect
knowledge about the channels to the eavesdropper. The transmitter only knows that the …

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 …

In this letter, we aim to achieve secure communication for a multiple-input single-output
(MISO) wiretap channel in the presence of multiple non-colluding eavesdroppers. It is …

We consider the problem of secure communication in wireless fading channels in the
presence of non-colluding passive eavesdroppers. The transmitter has multiple antennas …

We consider physical layer security in a multi-input multi-output multi-eavesdropper wiretap
channel and present an exact solution to the problem of secrecy rate maximization. A system …
