CSI-Based RF Fingerprinting of WiFi Devices: From Signal Processing to Deep Learning
Speaker: Prof. He CHEN, Department of Information Engineering at the Chinese University of Hong Kong
Date: 29/04/2024 (Monday)
Time: 11:00 – 12:00
Language: English
Venue: N21-5010

Abstract:
This talk introduces CSI-RFF, a new framework that uses micro-signals present in Channel State Information (CSI) to facilitate radio-frequency fingerprinting of commodity off-the-shelf (COTS) WiFi devices for open-set authentication. These micro-signals, termed ‘micro-CSI,’ primarily arise from imperfections in the RF circuitry and are detectable across WiFi 4/5/6 network interface cards (NICs). The challenge in leveraging micro-CSI for authentication stems from its entanglement with distortions introduced by wireless channels, referred to as true CSI. This complex interplay makes separating these components non-trivial. To address this, we have developed a signal space-based extraction technique targeted for Line-of-Sight (LoS) scenarios, which effectively isolates the channel distortions from micro-CSI.
