Fault Injection Resilience
Fault injections constitute a major threat to the security of embedded systems. The errors in the cryptographic algorithms have been shown to be extremely dangerous, since powerful attacks can exploit few of them to recover the full secrets. Most of the resistance techniques to fault attacks have relied so far on the detection of faults. We present in this paper another strategy, based on the resilience against fault attacks. The core idea is to allow an erroneous result to be outputted, but with the assurance that this faulty information conveys no information about the chip's secrets. We first underline the benefits of FIR: false positive are never raised, secrets are not erased uselessly in case of faults injections, which increases the card lifespan if the fault is natural and not malevolent, high potential of resistance even in the context of multiple faults. Then we illustrate two families of fault injection resilience (FIR) schemes suitable for symmetric encryption. The fir...
