In massive millimeter-wave (mmWave) multiple-input–multiple-output (MIMO) systems,
eavesdroppers may transmit the identical pilot sequences as legitimate users to manipulate …

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 coherent massive MIMO systems, the training phase provides opportunity for an active
eavesdropper to attack legitimate communication, which is known as pilot spoofing attack …

Secure communication in underlay spectrum sharing multi-user massive multiple-input
multiple-output systems with active eavesdropping is investigated. The primary base-station …

This paper investigates the secure transmission in multi-pair massive multiple-input multiple-
output amplify-and-forward (AF) relaying networks under active pilot spoofing attacks. The …

Massive MIMO systems are vulnerable to pilot spoofing attacks (PSAs) since the estimated
channel state information can be contaminated by the eavesdropping link, thus incurring …

In this paper, we investigate secure communication in a massive multiple-input multiple-
output (MIMO) system with multiple users and multiple eavesdroppers (Eve) under both pilot …

In this letter, we investigate secure transmission for multi-cell multi-user massive multiple-
input multiple-output systems with an active eavesdropper. During the uplink (UL) training …

To secure the legitimate communication, this paper proposes a pilot spoofing attack
detection algorithm in massive MIMO systems, in which the information of channel statistics …

In this paper, the achievable secrecy rate of a relay-assisted massive multiple-input multiple-
output (MIMO) downlink is investigated in the presence of a multi-antenna active/passive …
