Abstract: This paper gives the realization of differential power analysis attack of the decrypt encrypted circuits with DES. And the paper also gets the key of AES on the AtmelAES plat by using DPA attacks. The paper confirms the vulnerability of the AES algorithm facing the PDA attacks. And it is very necessary to improve the performance of the antiDPA attacks of AES.

Key words: advanced encryption standard(AES), differential power analysis(DPA), sidechannel attacks
