This study investigates the framework of associating multiple‐input–multiple‐output (MIMO)
beamforming with secure code to achieve unconditional secure communications in the …

In this paper, we consider secure communications in a multi-cell downlink multi-antenna
system, where each multi-antenna base station (BS) sends confidential messages to one …

Device-to-device (D2D) communication raises new transmission secrecy protection
challenges, since conventional physical layer security approaches, such as multiple …

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 …

This paper presents the optimal physical-layer security scheme of both primary user (PU)
and secondary user (SU) in the underlay multiple-input multiple-output cognitive-radio …

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

In this paper, we propose three relay selection schemes for full-duplex heterogeneous
networks in the presence of multiple cognitive radio eavesdroppers. In this setup, the …

In this paper, we study an energy harvesting scheme for a multiple-input-single-output
secrecy channel under imperfect channel state information case with either deterministic …

The issue of physical layer security for single-input-multiple-output (SIMO) wiretap channel
with uncoordinated cooperative jamming (UCJ) is addressed in this letter, and we focus on …

We consider a broadcast channel in which a multi-antenna transmitter (Alice) sends K
confidential information signals to K legitimate users (Bobs) in the presence of L …
