Abstract: We present a framework for forensic identification of RF devices using specially designed probe signals. This framework applies to a broad range of devices and models. Probe signals, device models, feature selection, and classifier design are described. For the device model, we introduce a method for determining a nonlinearity based on a known diode model. Experimental results are given to verify our approach.
