Internet of Things (IoT) is becoming an emerging paradigm to achieve ubiquitous
connectivity, via massive deployment of physical objects, such as sensors, controllers, and …

This paper investigates cooperative security in wireless networks, where a source (Alice)
intends to transmit a confidential message to a legitimate destination (Bob), with the help of …

Wireless communication is one of the key technologies that actualize the Internet of Things
(IoT) concept into the real world. Understanding the security performance of wireless …

In this article, we propose a lightweight security scheme for ensuring both information
confidentiality and transmission resiliency in the Internet-of-Things (IoT) communication. A …

This article studies secure communication in an Internet of Things (IoT) network, where the
confidential signal is sent by an active refracting reconfigurable intelligent surface (RIS) …

This paper, for the first time, examines the impact of transmitter-side correlation on the
artificial-noise (AN)-aided secure transmission, based on which a new power allocation …

In this correspondence, we investigate the physical layer security issue with the assistance
of a reconfigurable intelligent surface (RIS). In particular, we consider the single-input and …

In this paper, we study the secure multi-antenna transmission with artificial noise (AN) under
slow fading channels coexisting with randomly located eavesdroppers. We provide a …

Physical layer security, or information-theoretic security, has attracted considerable attention
recently, due to its potential to enhance the transmission secrecy of wireless …

In this article, we study the secure beamforming design for a two-way cognitive radio (CR)
Internet of Things (IoT) network aided with the simultaneous wireless information and power …
