1. A method of fault injection attack mitigation, the method comprising:
generating a corresponding representation of at least one of data or a component of a processing device;
locating the corresponding representation on a die of the processing device adjacent to a location on the die of at least one of the data or the component of the processing device within a predetermined distance, the predetermined distance less than a diameter of a laser spot of a laser fault injection device to mitigate a fault injection attack from the laser fault injection device; and
executing, based on a determination that the corresponding representation is different than at least one of the data or the component of the processing device, a mitigation procedure by the processing device.
