1. A computer-implemented method for performing device authentication based on physical communication signal characteristics, the method comprising:
obtaining, by a computing system comprising one or more computing devices, a plurality of physical signal samples associated with physical signals of a device on or attempting to connect to a network;
processing, by the computing system, the plurality of physical signal samples with a machine-learned fingerprint generation model to generate a device fingerprint for the device based at least in part on the plurality of physical signal samples; and
processing, by the computing system, the device fingerprint to generate an authentication classification for the device based at least in part on the device fingerprint.
