Multi-User Cooperation for Covert Communication Under Quasi-Static Fading

Jinyoung Lee, Duc Trung Dinh, Hyeonsik Yeom +2

This work studies a covert communication scheme for an uplink multi-user scenario in which some users are opportunistically selected to help a covert user. In particular, the selec…

Secure Power Control for Downlink Cell-Free Massive MIMO With Passive Eavesdroppers

Junguk Park, Sangseok Yun, Jeongseok Ha

This work studies secure communications for a cell-free massive multiple-input multiple-output (CF-mMIMO) network which is attacked by multiple passive eavesdroppers overhearing co…

Secret Key Agreement with Large Antenna Arrays under the Pilot Contamination Attack

Sanghun Im, Hyoungsuk Jeon, Jinho Choi +1

We present a secret key agreement (SKA) protocol for a multi-user time-division duplex system where a base-station (BS) with a large antenna array (LAA) shares secret keys with use…

On the Role of Transmit Correlation Diversity in Multiuser MIMO Systems

Junyoung Nam, Giuseppe Caire, Young-Jo Ko +1

Correlation across transmit antennas, in multiple antenna systems (MIMO), has been studied in various scenarios and has been shown to be detrimental or provide benefits depending o…

Secrecy Capacity over Correlated Ergodic Fading Channel

Hyoungsuk Jeon, Namshik Kim, Minki Kim +2

We investigate the secrecy capacity of an ergodic fading wiretap channel in which the main channel is correlated with the eavesdropper channel. In this study, the full Channel Stat…
