An Adversarial Model for Fault Analysis Against Low-Cost Cryptographic Devices

This contribution presents a unified adversarial model for fault analysis which considers various natures of faults and attack scenarios with a focus on pervasive low-cost cryptographic devices. According to their fault induction techniques we distinguish the non-invasive adversary, the semi-invasive adversary, and the invasive adversary. We introduce an implementation based concept of achievable spatial and time resolution that results from the physical fault induction technique. Generic defense strategies are reviewed.
