Research in Correlation Algebraic Attack on AES First Round

摘要

Create a Hamming-Weight model, combine it with traditional algebraic attack, and achieve the Correlation algebraic attack on the first round of AES128 according to correlation coefficient r. The attack experiment proves that owing to this proposed model, it can evidently distinguish the right key bytes from the wrong ones by this function with further computed correlation coefficient r, and in certain time we can acquire all the true key bytes.
