Towards Scalable and Channel-Robust Radio Frequency Fingerprint Identification for LoRa
Guanxiong Shen, Junqing Zhang, Alan Marshall +1
Radio frequency fingerprint identification (RFFI) is a promising device authentication technique based on the transmitter hardware impairments. In this paper, we propose a scalable…
Radio Frequency Fingerprint Identification for LoRa Using Spectrogram and CNN
Guanxiong Shen, Junqing Zhang, Alan Marshall +2
Radio frequency fingerprint identification (RFFI) is an emerging device authentication technique that relies on intrinsic hardware characteristics of wireless devices. We designed…
A Beaconless Asymmetric Energy-Efficient Time Synchronization Scheme for Resource-Constrained Multi-Hop Wireless Sensor Networks
Xintao Huan, Kyeong Soo Kim, Sanghyuk Lee +2
The ever-increasing number of WSN deployments based on a large number of battery-powered, low-cost sensor nodes, which are limited in their computing and power resources, puts the…
Channel-Envelope Differencing Eliminates Secret Key Correlation: LoRa-Based Key Generation in Low Power Wide Area Networks
Junqing Zhang, Alan Marshall, Lajos Hanzo
This paper presents automatic key generation for long-range wireless communications in low power wide area networks (LPWANs), employing LoRa as a case study. Differential quantizat…
Cell-free Massive MIMO Networks: Optimal Power Control against Active Eavesdropping
Tiep M. Hoang, Hien Quoc Ngo, Trung Q. Duong +2
This paper studies the security aspect of a recently introduced network ("cell-free massive MIMO") under a pilot spoofing attack. Firstly, a simple method to recognize the presence…
Securing Wireless Communications of the Internet of Things from the Physical Layer, An Overview
Junqing Zhang, Trung Q. Duong, Roger Woods +1
The security of the Internet of Things (IoT) is receiving considerable interest as the low power constraints and complexity features of many IoT devices are limiting the use of con…
