Webdescribe AES using matrix on GF(28) but we try to keep the notations of [1]. The AES is a block cipher with block length to 128 bits, and support key lengths N k of 128, 192 or 256 … WebIn this paper we describe two different DFA attacks on the AES. The first one uses a fault model that induces a fault on only one bit of an intermediate result, hence allowing us to obtain the key by using 50 faulty ciphertexts for an AES-128. The second attack uses a more realistic fault model: we assume that we may induce a fault on a whole byte.

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 …
