Physical-layer key generation (PKG) based on channel reciprocity has recently emerged as
a new technique to establish secret keys between devices. Most works focus on pairwise …

Shared secret key generation from wireless channel characteristics has attracted a lot of
research attention in recent years due to its low computational overhead and potentials to …

We investigate the optimality and power allocation algorithm of beam domain transmission
for single-cell massive multiple-input multiple-output (MIMO) systems with a multi-antenna …

Secret key generation from reciprocal multi-antenna channels is an interesting alternative to
cryptographic key management in wireless systems without infrastructure access. In this …

In future practical deployments of massive multi-input multi-output (MIMO) systems, the
number of radio-frequency (RF) chains at the base stations (BSs) may be much smaller than …

In this paper, we study the design of secure communication for time-division duplex multi-
cell multi-user massive multiple-input-multiple-output (MIMO) systems with active …

In this paper, we investigate the secure downlink transmission in a multi-user massive
multiple-input multiple-output system assuming there is a passive multi-antenna …

For the single-cell massive multiple-input multiple-output (MIMO) downlink transmission, we
investigate an artificial noise (AN) assisted secure transmission strategy where the base …

In this work, we present a scheme of physical layer secret key generation for Millimeter wave
(mmWave) Massive MIMO system. Our scheme is compatible with current hardware …

We investigate physical layer security in massive multiple-input multiple-output multicast
transmission where the base station only knows the statistical channel state information of …
