Strengthening hardware AES implementations against fault attacks
Marc Jóye, Pascal Manet, Jean-Baptiste Rigaud · IET Information Security · 2007
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. Novel techniques to implement a duplication scheme for the AES are proposed. Remarkably, the proposed techniques do not impact on the throughput/area ratio and better withstand a large variety of known fault attacks.
