Abstract:

The power consumption of a digital circuit implemented in the CMOS technology depends on the data that the circuit is processing. Power analysis attac ks based on the fact pose a serious threat to cryptographic devices for extracting secret data. In this paper, we discuss the vulnerability of AES hardw are implementations, and present the hypothetical circuit model. We also assess the susceptibility to differential power analysis （DPA） and correlatio  on power analysis （CPA） attacks using different statistical methods in theoretical estimation. Furthermore, we give some possible hardware countermeas  sures against PA attacks.

Key words: AES, side-channel attack, power analysis, Hamming-weight, countermeasure
