This article investigates the covertness and secrecy of wireless communications in an
untrusted relay-assisted device-to-device (D2D) network consisting of a full-duplex base …

This letter examines the physical layer security of a cellular network with inband underlay
relay-aided Device-to-Device (D2D) communication, considering the scenario where the …

Device-to-device (D2D) communications underlaid cellular networks have emerged as a
promising network architecture to provide extended coverage and high data rate for various …

This paper investigates the physical layer security and data transmission in cellular networks
with inband underlay Device-to-Device (D2D) communications, where there is no direct link …

In this paper, we study the underlay relay-aided Device-to-Device (D2D) communications to
improve the physical layer (PHY) security of the cellular network. We propose a cooperative …

Internet of Things (IoT) systems are of paramount importance to provide ubiquitous wireless
connectivity for smart cities. However, such systems are facing security challenges due to …

We exploit both covert communication and friendly jamming to propose a friendly jamming-
assisted covert communication and use it to doubly secure a large-scale device-to-device …

Device-to-device (D2D) communication raises new transmission secrecy protection
challenges, since conventional physical layer security approaches, such as multiple …

This paper investigates the physical layer security and data transmission for the underlay
device-to-device (D2D) networks, and considers a combination of the reconfigurable …

In this article, we investigate device-to-device (D2D) relay enabled covert communications.
Safety zone is employed to isolate the eavesdroppers from the transmitters and receivers …
