1. A device, comprising:
a sensor configured to register sensor data that is indicative of a measurement of physical behavior of an authentication chip of a component; and
an authentication circuit configured to:
implement a machine learning model that is trained to classify components into originals and forgeries using sensor data that describe physical behavior of authentication chips of the component;
transmit the registered sensor data to the machine learning model; and
authorize use of the component by the device when the machine learning model classifies the component as an original,
wherein the sensor is configured to register the sensor data during a generation of authentication information requested from the component, and
wherein the sensor data that is registered is separate from the authentication information.
