Today, wireless networks become the most popular way to communicate. However,
information can be easily eavesdropped or extracted by eavesdroppers due to the broadcast …

This paper investigates impact of hardware impairments on the probability of Non-zero
Secrecy Capacity (NSC) of multi-hop relay networks. In the considered protocol, multiple …

Due to the broadcast nature of wireless channels, the two-way system can be eavesdropped
on when a confidential message is transmitted, which is one of the motivations of this paper …

We analyze the secrecy outage probability of selective relaying wiretap channels with K
decode-and-forward (DF) relays and N collaborative eavesdroppers. In the main channel …

Recently, three useful secrecy metrics based on the partial secrecy regime were proposed to
analyze secure transmissions on wireless systems over quasi-static fading channels …

A distributed wireless network with one source, one destination, one eavesdropper and
multiple Decode-and-Forward (DF) relays is investigated. A two-slot cooperative relaying …

The authors investigate the secrecy performance of a cooperative relaying network, wherein
a fixed source communicates with a fixed destination via an amplify‐and‐forward mobile …

In this paper, the secrecy outage probability of threshold-based decode-and-forward (DF)
cooperative relay network is evaluated. Unlike other works to date, we assume combining of …

This paper investigates the secure communications of multiuser untrusted amplify‐and‐
forward relay networks in the presence of direct links. In the considered system, one user is …

This paper deals with the challenge of providing information-theoretic secrecy in a two-hop
wireless channel with multiple untrusted relay nodes. Instead of perfect secrecy (in the …
