Fault analysis is a very powerful technique to break cryptographic implementations. In particular, bit faults analysis (BLFA), where faults are injected by flipping one or a few isolated bits, are among the most efficient of the lot. capabilities and sophisticated key extraction skills. Algebraic fault analysis (AFA) [1] is a good analysis technique for BLFA. Compared with differential fault analysis (DFA), AFA relies on the automation from machine solvers.
