Abstract: | In this paper, based on a differential property of two round Lai-Massay scheme in a fault model, we present an improved fault attack on the block cipher FOX64. Our improved method can deduce any round subkey through 4.25 faults on average (4 in the best case), and retrieve the whole round sub-keys through 45.45 faults on average (38 in the best case). The technique of the proposed attack in this paper can also be easily extended to other series of FOX. |
