WebAug 21, 2010 · The naive implementation of AES is known to be vulnerable to Differential Fault Analysis (DFA). We can find the key of AES-128 (AES with 128-bit key) with one pair of correct and faulty cipher texts. Recently several works on the extension of the attack to AES with 192 and 256-bit key have been published. Due to the longer key size and the … WebJul 19, 2024 · Note that the DFA above accepts empty string as a "number" divisible by 3. This can easily be fixed by adding one more intermediate state in front: Conversion to theoretical regular expression can be done with the normal process. Conversion to practical regex in flavors that supports recursive regex can be done easily, when you have got the …
