ORF: On-board Radiometric Fingerprinting

Abstract: Radiometric fingerprinting systems leverage unique physical-layer signal characteristics originating from individual hardware imperfections to identify transmitter devices. However, existing systems are limited by the need for specialized hardware and non-trivial computations to capture physical-layer signals and extract fingerprinting features, hindering their pervasive deployment. ORF, for the first time, demonstrates the feasibility of implementing an entire radiometric fingerprinting system on a low-cost and low-power embedded system on chip, with over 92% average accuracy on the task of identifying one out of 32 different transmitter devices.
