Strengthening Hardware AES Implementations against Fault Attack

Abstract

Differential fault attacks become a threat of increasing importance against cryptographic devices. One of the most efficient hardware countermeasures for block ciphers to prevent such attacks relies on duplication. In this paper, we propose novel techniques to implement a duplication scheme for the AES. Remarkably, our implementation techniques do not impact the ratio throughput/area. Furthermore, they rule out known fault attacks or increase their success complexity.
