We consider a cooperative relaying network in which a source communicates with a group
of users in the presence of one eavesdropper. We assume that there are no source-user …

We investigate secure transmission for multiuser relay networks, where the undesired users
who are not selected for data reception may overhear the source message as …

This paper proposes relay selection to increase the physical layer security in multiuser
cooperative relay networks with multiple amplify-and-forward relays, in the presence of …

In this paper, we study the information-theoretical security of a downlink multiuser
cooperative relaying network with multiple intermediate amplify-and-forward (AF) relays …

This paper considers secrecy of a three node cooperative wireless system in the presence of
a passive eavesdropper. The threshold-selection decode-and-forward relay is considered …

In this paper, we consider secure communications of one source-destination pair in wireless
multi-hop decode-and-forward (DF) relay networks. In the presence of an eavesdropper, we …

In this paper, we investigate the secrecy outage performance of a dual-hop decode-and-
forward (DF) threshold-based cooperative relay network, both with and without the direct …

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, we study a downlink multiuser network in which one base station sends its
message to one of multiple users, assisted by one of multiple intermediate decode-and …

This paper studies the cooperative transmission for securing a decode-and-forward (DF) two-
hop network where multiple cooperative nodes coexist with a potential eavesdropper. Under …
