In this paper, we consider the problem of secure communications for a four-node system
consisting of one source, one destination, one eavesdropper, and one helper. We …

This paper mainly describes the transmission reliability and physical layer security of
multiantenna decode‐and‐forward relay networks over the κ‐μ shadowed fading …

This paper investigates the physical-layer security of the modify-and-forward (MF) protocol in
multi-relay and multieavesdropper networks. Three relay selection critera are developed …

This paper investigates the secure performance of multi‐antenna decode‐and‐forward (DF)
relaying networks where the Nakagami‐m fading channel is taken into account. In practice …

In this paper we investigate a cooperative jamming (CJ) strategy based Stackelberg security
game to improve physical layer security over multiuser OFDMA networks. Each source node …

In this paper, we propose a random phase shifting scheme applied to modulated data
symbols of a dual-hop decode-and-forward (DF) relaying system to enhance its secrecy …

We proposed a new physical layer technique that can enhance the security of cooperative
relay communications. The proposed approach modifies the decoded message at the relay …

This paper investigates the security at the physical layer of cooperative relay
communications. Inspired by the principle of physical-layer network coding (PNC), we …

In this paper, we investigate the secure transmission problem of cooperative communication
systems where a potential malicious eavesdropper is existing. Based on the more general …

This paper investigates the security at the physical layer in cooperative wireless networks
(CWNs) where the data transmission between nodes can be realised via either direct …
