Information theoretic security has recently emerged as an effective physical layer approach
to provide secure communications. The outage performance of such a secrecy …

In this paper, the impact of multiple active eavesdroppers on cooperative single carrier
systems with multiple relays and multiple destinations is examined. To achieve the secrecy …

We consider a cooperative wireless network in the presence of one or more eavesdroppers,
and exploit node cooperation for achieving physical (PHY) layer based security. Two …

The feasibility of physical-layer-based security approaches for wireless communications in
the presence of one or more eavesdroppers is hampered by channel conditions. In this …

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 studies physical-layer secure transmissions from a transmitter to a legitimate
receiver against an eavesdropper over slow fading channels, taking into account the impact …

In this work, by considering a variety of realistic hardware impairments, we aim to enhance
the security of a cooperative relaying network, where a source intends to transmit its …

In this correspondence, we consider a confidential communication through slow non-
selective correlated Rayleigh fading channel, where a single antenna transmitter …

This paper investigates cooperative security in wireless networks, where a source (Alice)
intends to transmit a confidential message to a legitimate destination (Bob), with the help of …

We investigate the physical layer security in cooperative wireless networks where a source
(Alice) transmits a confidential message to a destination (Bob) with the help of a cooperative …
