Multi-Antenna Jammer-Assisted Secure Short Packet Communications in IoT Networks
Future Internet, 2023 In this work, we exploit a multi-antenna cooperative jammer to enable secure short packet communications in Internet of Things (IoT) networks. Specifically, we propose three jamming schemes to combat eavesdropping, i.e., the zero forcing beamforming (ZFB)

Secure short-packet communications using a full-duplex receiver
International Journal of Intelligent Networks, 2023 In this work, we consider the physical layer security in short-packet communications, where a full-duplex (FD) receiver receives information signals from a source while generating artificial noise (AN) to confuse an eavesdropper.

Throughput maximization in multi-hop wireless networks under a secrecy constraint [PDF]
Computer Networks, 2016 This paper analyzes the throughput of industrial communication networks under a secrecy constraint. The proposed scenario is composed by sensors that measure some relevant information of the plant that is first processed by aggregator node and then sent to the control unit.

Virtual full-duplex buffer-aided relay selection schemes for secure cooperative wireless networks
EURASIP Journal on Wireless Communications and Networking, 2022 This paper considers secure communication in buffer-aided cooperative wireless networks in the presence of one eavesdropper, which can intercept the data transmission from both the source and relay nodes.
