Power Attack of MARS and Rijndael
MARS和Rijndael的能量攻击

MARS and Rijndael are analyzed by using power attack. It is shown that the complexities on MARS are 2208, 2168 and 2116 for 256, 192 and 128 bits key respectively, the complexities on Rijndael are 2131, 299 and 267 for 256, 192 and 128 bits key respectively. Although the complexities are too big to implement, the approach presented in this paper reduces greatly the key size of MARS and Rijndeal.
