Abstract :
CLEFIA is a 128-bit block cipher designed newly by Sony Corporation. In this paper, a differential power analysis attack method on every byte of CLEFIA round keys is presented. Through this attack, the round keys can be obtained, and then the 128-bit encryption key can be calculated out. The results of simulation experiments indicate that this attack is effective and practical on the CLEFIA cipher.
