In this paper, we investigate secure communications uplink transmissions, where there are a
base station (BS) with M receive antennas, K mobile users each with a single antenna, and …

This paper studies cooperative transmission for securing a two‐hop network where the
eavesdropper can wiretap the relay channels. With outdated channel state information (CSI) …

We study a relay and user selection scheme to improve the secrecy performance of
cooperative multi-user multiple amplify-and-forward (AF) relay network. Nevertheless, relay …

In this paper, the secrecy outage performance of a three-node amplify-and-forward relay
network with an untrustworthy relay is investigated. To enable a secure transmission, we …

As an important part of the intelligent transportation system (ITS), vehicular networks can
provide drivers and passengers with more comfortable and convenient services such as …

This paper studies the secrecy performance of an untrusted amplify-and-forward relaying
network where both the relaying and the direct links are used to convey the source's …

In this paper, we highlight a secure reactive amplify‐and‐forward relaying system over
Nakagami‐m fading channels in the presence of multiple eavesdroppers. We study a …

We propose in this paper a physical layer security (PLS) scheme for dual-hop cooperative
networks in an effort to enhance the communications secrecy. The underlying model …

In this paper, we study secure outdated-channel-state-information amplify-and-forward (SO-
CSI-AF) relaying network using partial relay selection method. The best relay node is …

In this paper, we investigate secure two-user AF relaying networks based on a destination
assisted cooperative jamming (DACJ). We consider two sources, one destination, one …
