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 …

We consider transmission of confidential data over multiple-input single-output multiple-
eavesdropper (MISOME) Rayleigh-fading wiretap channels. The transmitter has access to …

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 …

This paper considers a scenario in which an Alice-Bob pair wishes to communicate in secret
in the presence of an active Eve, who is capable of jamming as well as eavesdropping and …

We consider a practical scenario of the Gaussian multiantenna wiretap channel where a
transmitter with no channel state information wishes to send a confidential message to its …

Consider a full-duplex (FD) bidirectional secure communication system, where two
communication nodes, named Alice and Bob, simultaneously transmit and receive …

This letter considers the secure MIMO transmission in a wireless environment, in which one
transmitter (Alice), one receiver (Bob) and one eavesdropper (Eve) are involved. Apart from …

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

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 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 …
