Abstract:
In the era of the Internet of Things, when sensors and actuators are pervasively used to construct different critical applications, protecting cybersecurity has become the focus of attention. It is challenging to provide reliable and robust protections for resource-constrained devices such as sensors because of their limited computing, storage, and energy budgets. In this Ph.D. mid-term seminar, I present two approaches to enhance cybersecurity for wireless networks by relying on physical-layer properties. The radio channel poses an essential role for leveraging signal physical-layer information as it is susceptible to environmental dynamics. The first approach utilizes the imperfections in the transmitter hardware electronics to build an identification system, the so-called radiometric fingerprinting

The robustness of fingerprinting systems under complex channel conditions is a critical challenge that makes their application in real-world scenarios difficult. To tackle this research gap, I will introduce RRF, a robust radiometric fingerprinting system based on a hybrid architecture that combines wireless channel simulation, signal processing, and machine learning to augment system reliability. The second approach learns the channel variation pattern and uses it as a dynamic spatial signature based on wireless link characteristics. In our research, we explore a novel use case with wearables. Leveraging the body motion and lightweight statistical algorithm, we propose an intrusion detection system to capture spoofing attacks by tracking the pattern of physical layer signal features.
