A method includes receiving an output signal from a sensor, recovering a noise signal from the output signal, comparing the noise signal with a stored baseline noise signature, and reporting authentication of the sensor if the comparison is within a pre-determined error limit. A sensor authentication apparatus, comprises a processor and a memory operably coupled with the processor. Instructions, when executed, cause the processor to separate a noise signal from a measured signal, and detect a noise signature match by comparing the noise signal with at least one stored baseline noise signature associated with the sensor. A sensor authentication system comprises a sensor authentication unit and a data acquisition unit. At least one of the sensor authentication unit and the data acquisition unit is configured to compare a noise signal with a baseline noise signature to authenticate the at least one sensor from among a plurality of sensors.
