Abstract
A system that includes memory and a microcontroller including an analog-to-digital converter (ADC) and in communication with the memory. The microcontroller is configured to define a fingerprint that includes a baseline measurement of side-channel traces of a side-channel retrieved from the ADC, during an enrollment period of the system, wherein the enrollment period includes measuring voltage prior to runtime operation, receive a runtime measurement from the ADC that includes voltage of at least the separate microcontroller during runtime, compare the runtime measurement to the fingerprint, and in response to the measurement exceeding a threshold, executing a countermeasure operation against software ran by the separate processor.
