Nonorthogonal multiple access (NOMA) has been viewed as a potential candidate for the
upcoming generation of wireless communication systems. Comparing to traditional …

In this article, we study the physical-layer security (PHY-security) improvement method for a
downlink nonorthogonal multiple access (NOMA) system in the presence of an active …

In recent years, physical layer security has been considered as an effective method to
enhance the information security beside the cryptographic techniques that are used in upper …

In this paper, we consider the physical layer (PHY) security problem for hybrid wiretapping
wireless systems in millimeter wave transmission, where active eavesdroppers (AEs) and …

In adversarial scenarios, it is crucial to timely monitor what tactical messages that opponent
transmitters are sending to intended receiver (s), and disrupt the transmissions immediately …

In the insecure transmission environment, compared with the passive eavesdropper (Eve),
the active Eve plays a more threatening role in the physical layer security (PLS), since it can …

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 …

In this article, a wireless wiretap channel with artificial noise assisted transmission and
active eavesdropper is considered, where, wireless channel coefficients are correlated …

This paper explores the role of multiple antennas in mitigating jamming attacks for the
Rayleigh fading environment with exogenous random traffic arrival. The jammer is assumed …

The growing concern of secure communication becomes more challenging when
encountering a hybrid Full-duplex (FD) attacker possessing the dual capability to perform …
