Research in HW Algebraic Attack on AES First Round

Combine the Hamming-Weight model of DPA with traditional algebraic attack, and achieve the power algebraic attack on the first round of AES-128.In the attack experiment, improve the function of Hamming-Weight, and prove that it can evidently distinguish the right key bytes from the wrong ones by further computed correlation coefficient r, and then acquire all the true key bytes in certain time.It is experimentally proved that this method is more applicable and more effective than other corresponding research.
