This dissertation aims to conduct research on security issues of 5G wireless networks, which
are vulnerable to external security threats while supporting services for a massive number of …

In this paper, we study the secrecy performance of short packet secure communications over
a fading wiretap channel when there are multiple receivers and eavesdroppers. In particular …

5G network is expected to support massive user connections and exponentially increasing
wireless services, which makes network security unprecedentedly important. Unlike …

Recently, the physical layer has gained a more prominent role on the security context of
wireless networks due to its potentiality on providing more effective solutions to safeguard …

In this paper, we investigate secure short packet transmission from a legitimate transmitter to
a receiver in the presence of an active eavesdropper. The aim is to gain more insights into …

Mobile data traffic is growing daily and this presents a significant challenge as the broadcast
nature of wireless channels makes it extremely vulnerable to security breaches. A recent …

Physical layer security is a promising approach that can benefit traditional encryption
methods. The idea of physical layer security is to take advantage of the propagation …

This paper studies the performance of short packet communications in the presence of
multiple eavesdroppers. We start our investigation by examining the fading wiretap channel …

The current research on physical layer security is far from implementations in practical
networks, arguably due to impractical assumptions in the literature and the limited …

Physical layer security (PLS) has proven to be a potential solution for enhancing the security
performance of future 5G networks, which promises to fulfill the demands of increasing user …
