The security of SHA-3 against different kinds of attacks are of vital importance for crypto systems with SHA-3 as the security engine. In this paper, we look into the differential fault analysis of SHA-3, and this is the first work to conquer SHA3-224 and SHA3-256 using differential fault analysis. Comparing with one existing related work, we relax the fault models and make them realistic for different...
A common algorithm-level effective countermea-sure against side-channel attacks is random masking. However, second-order attack can break first-order masked devices by utilizing power values at two time points. Normally 2nd-order attacks require the exact temporal locations of the two leakage points. Without profiling, the attacker may only have an educated guessing window of size nw for each potential...
