Due to the open nature of wireless communication systems, the data transmission over
these networks are vulnerable to malicious attack. To safeguard the transmitted data …

This paper investigates the secrecy performance of a two-user downlink non-orthogonal
multiple access systems. Both single-input and single-output and multiple-input and single …

Reconfigurable intelligent surfaces (RISs) have drawn significant attention due to their
capability of controlling the radio environment and improving the system performance. In this …

This paper studies the physical layer security (PLS) of a vehicular network employing a
reconfigurable intelligent surface (RIS). RIS technologies are emerging as an important …

In this paper, we consider an underlay multiple-input-multiple-output (MIMO) cognitive radio
network (CRN) including a pair of primary nodes, a couple of secondary nodes, and an …

We analyze a secure dual-hop mixed radio frequency-free space optical (RF-FSO) downlink
simultaneous wireless information and power transfer system. The FSO link and all RF links …

In this paper, we study the secrecy performance of a mixed radio frequency-free space
optical (RF-FSO) transmission systems. All RF links experience Nakagami-m fading and the …

In this letter, we study the physical layer secrecy performance of the classic Wyner's wiretap
model over double Rayleigh fading channels for vehicular communications links. We derive …

In this paper, we provide a global framework analysis of a dual-hop mixed radio frequency
(RF)/free space optical (FSO) system with multiple branches/relays wherein the first and …

In this article, we study the physical layer security of free-space optical (FSO)
communications under different eavesdropping scenarios. More specifically, the secrecy …
