In this paper, we investigate secure communications in two-hop wireless relaying networks
with one eavesdropper. To prevent the eavesdropper from intercepting the source message …

In this paper, we study opportunistic relay selection in cooperative networks with secrecy
constraints, where a number of eavesdropper nodes may overhear the source message. To …

Physical layer security has recently attracted considerable attention in the context of
information‐theoretic point of view. In this paper, we investigate relay selection schemes for …

In this letter, we study relay-aided networks with presence of single eavesdropper. We
provide joint beamforming design of the source and relay that can minimize the overall …

In this letter, a generalized multi-relay selection scheme is proposed to improve the security
in a cooperative relay network. Assuming that only the statistical channel state information of …

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 …

In this paper, we examine the secrecy performance of two-way relaying between a large-
scale multiple antenna base station (BS) and a single antenna mobile user (MU) in the …

In this paper, we study the impact of correlated fading on the secrecy performance of
multiple decode-and-forward (DF) relaying with outdated relay selection. It is assumed that …

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 …

This paper investigates the problem of secure communication for amplify-and-forward (AF)
systems with untrustworthy relay nodes. To achieve positive secrecy rate, the destination …
