  • Systems and methods for identifying transmitters
    Patent number: 12402006
    Abstract: A signal transmitted by a trusted transmitter is sampled, and a machine-learning algorithm is trained using these samples to learn to distinguish the signal characteristics of the trusted transmitter from the signal characteristics of other transmitters. The machine-learning parameters learned to distinguish the trusted transmitter's signals can then be exported allowing other devices to authenticate signals from the trusted transmitter. Since the signal characteristics of the trusted transmitter is based on manufacturing variations, the transmitters of unauthorized users should be unable to replicate the signal characteristics of the trusted transmitter. Thus, the transmitters of unauthorized users should not be usable to spoof a device that uses the exported parameters to authenticate messages from the trusted transmitter.
