Abstract
Aspects of the present disclosure involve systems, methods, apparatus, and computer-readable media for mitigating laser-based fault injection attacks against one or more processing devices. Techniques may include 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, 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. One example may include hashing, using a secure hashing function, security data to generate integrity data corresponding to the security data and storing the security data and the integrity data in adjacent memory locations in a memory device.
