In this paper, a network with multiple-antenna legitimate nodes and single-antenna
illegitimate nodes (INs) with different trust degrees (TD), such as trusted cooperative …

This paper is concerned with the relay and jammers selection in two-way cooperative
networks to improve their physical layer security. Three different categories of selection …

Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

The use of cooperation to increase the information-theoretic secrecy in a decentralized ad-
hoc wireless network is investigated. In particular, four cases of cooperative relaying are …

In this paper, we investigate the roles of cooperative jamming (CJ) and noise forwarding
(NF) in improving the achievable secrecy rates of a Gaussian wiretap channel (GWT) when …

Physical layer security is an emerging security field that explores the possibilities of
achieving perfect secrecy data transmission between the intended network nodes, while …

This paper proposes a new joint cooperative beamforming and jamming (JCBJ) scheme for
improving the physical layer security of decode-and-forward wireless networks where a …

Physical layer security is an efficient technique to realize security in wireless network without
relying on conventional cryptographic techniques. In cooperative networks with secrecy …

In this paper, we propose a hybrid cooperative scheme to improve the secrecy rate for a
cooperative network in presence of multiple relays. Each relay node transmits a mixed …

We investigate the problem of physical layer security in a wireless cooperative network,
where communication is assisted by the untrusted relay. It is impossible for the amplify-and …
