Side-channel attacks on block ciphers and public key algorithms have been discussed extensively, but only a few systematic studies on the applicability of side-channel attacks to stream ciphers could be found. The objective of the present study is to develop general differential power analysis techniques which can be employed to attack the stream ciphers with linear feedback shift registers. To illustrate...
In this paper we discuss correlation power analysis attack against stream cipher MICKEY v2. In such attacks, we use Hamming-Distance model to simulate the power consumption. Hamming-Distance model is a more accurate description to power consumption than other models such as Hamming-Weight, bit model etc. Generally, Hamming-Distance model is used to map the transitions that occur at the cells' outputs...
