Quadratic residue codes are introduced as an effective and efficient fault detection technique to protect cryptographic devices against fault attacks. In this paper, we re-consider these codes in an adversarial model, where a powerful attacker can introduce faults with high precision and accuracy. We present two analysis techniques that can lead to successful attacks against quadratic codes if the...
We propose a new class of error detection codes, {\em quadratic dual residue codes}, to protect cryptographic computations running on general-purpose processor cores against fault attacks. The assumed adversary model is a powerful one, whereby the attacker can inject errors anywhere in the data path of a general-purpose microprocessor by bit flipping. We demonstrate that quadratic dual residue codes...
