Abstract
Various embodiments of the present disclosure provide fault injection attack mitigation for an integrated circuit. In one example, an embodiment provides for providing a sampling clock signal to both high voltage threshold (HVT) cells and low voltage threshold (LVT) cells of a fault-to-time converter sensor of an integrated circuit, providing output of the HVT cells and the LVT cells to an encoder stage of the fault-to-time converter sensor, and detecting one or more fault injection attacks with respect to the integrated circuit based on output of the encoder stage.
