In this paper the authors present a differential fault attack that can be applied to the AES using a single fault. They demonstrate that when a single random byte fault is induced at the input of the eighth round, the AES key can be deduced using a two stage algorithm. The first step has a statistical expectation of reducing the possible key hypotheses to 232, and the second step to a mere 28. Furthermore, they show that, with certain faults, this can be reduced to two key hypothesis.
