As a complement to high-layer encryption techniques, physical layer security has been
widely recognized as a promising way to enhance wireless security by exploiting the …

Due to the malicious attacks in wireless networks, physical layer security has attracted
increasing concerns from both academia and industry. The research on physical layer …

This paper investigates the physical layer security of non-orthogonal multiple access
(NOMA) in large-scale networks with invoking stochastic geometry. Both single-antenna and …

The fifth generation (5G) network will serve as a key enabler in meeting the continuously
increasing demands for future wireless applications, including an ultra-high data rate, an …

In this correspondence, we investigate the physical layer security for cooperative
nonorthogonal multiple access (NOMA) systems, where both amplify-and-forward (AF) and …

Wireless energy harvesting (EH) is a promising solution to prolong lifetime of power-
constrained networks such as military and sensor networks. The high sensitivity of energy …

This paper considers transmit antenna selection (TAS) and receive generalized selection
combining (GSC) for secure communication in the multiple-input-multiple-output wiretap …

In this paper, we consider a large scale multiple input multiple output (LS-MIMO) relaying
system, where an information source sends the message to its intended destination aided by …

This paper considers a multiple-input-multiple-output (MIMO) cognitive wiretap system over
Nakagami-m channels with generalized selection combining (GSC), where confidential …

We analyze and optimize the secrecy performance of artificial noise (AN) in multi-input
single-output wiretap channels with multiple antennas at the transmitter and a single …
