  • Randomizing countermeasures for fault attacks
    Patent number: 9661015
    Abstract: A device may include countermeasure circuitry that provides a countermeasure check that protects device logic. The device may also include enforcement circuitry that non-deterministically enforces the countermeasure check on the device logic so that the device logic is not always protected by a countermeasure action within the countermeasure check. The device may non-deterministically enforce the countermeasure check according to an enforcement rate, and the device may adjust the enforcement rate depending on a priority of the device logic or device logic portion protected by a particular countermeasure check.
