We present combined attacks on the AES key schedule based on the work of Roche et al. [1]. The main drawbacks of the original attack are: the need for high repeatability of the fault, a very particular fault model and a very high complexity of the key recovery algorithm. We consider more practical fault models, we obtain improved key recovery algorithms and we present more attack paths for combined attacks on AES. We propose to inject faults on the different operations of the key schedule… CONTINUE READING
