While the millimeter-wave (mmWave) communication is less susceptible against the
conventional wiretapping attack due to its short transmission range and directivity, this paper …

The massive multiple input multiple output (mMIMO) provides reliable base station (BS) for
the mobile users (MUs) with CSI (channel state information) and jointly offers spectral …

In this paper, we consider a cooperative orthogonal frequency division multiple access
(OFDMA) system, where a source communicates with multiple users with the help of an …

Non-orthogonal multiple access (NOMA) systems have indicated that they can provide
higher spectral efficiency and secrecy capability compared with orthogonal multiple access …

This article studies the secrecy rate optimization in the downlink transmission of a dual‐
functional radar‐communication system, under the simultaneous wireless information and …

In this paper, we consider a two-way relay (TWR) network that two source nodes (SNs) with
multiple antennas exchange data to each other via a relay node (RN) with multiple …

In this letter we present a physical-layer-security (PLS) experimental platform that realizes
secure transmission over a two-way untrusted relaying system. A novel PLS approach called …

In this paper, a 5G mobile communication system is considered with cooperative
environment. The mobile and base-station node communicate with each other through a …

This letter proposes a key exchange scheme for the untrusted relay system, where the relay
not only assists in message transmission but also tries to recover messages. Terminal users …

User privacy protection is considered a critical issue in wireless networks, which drives the
demand for various secure information interaction techniques. In this article, we introduce an …
