Abstract: The method for authenticating a first device, the method including receiving RF signals from the first device, acquiring feature data from the received RF signals, fitting a model for authenticating the first device using the acquired feature data, storing in memory the fitted model in a second device, and, by the second device receiving a new RF signal from a device to authenticate, acquiring feature data from the new RF signal, and determining whether or not the device to authenticate is the first device by transmitting the feature data, acquired from the new RF signal, as input to the fitted model, the feature data acquired from a RF signal includes values of only one of an in-phase component and a quadrature component of the RF signal over time.
