Abstract
Due to the absence of an alternative algorithm SHA-2, NIST (National Institute of Standards and Technology) is proceeding to development project of SHA-3. NIST announced five candidates of the final round at the end of 2010. Side-channel attack scenarios of five candidates for SHA-3 final round have been proposed. In this paper, we prove the possibility of the analysis against 32-bit modular addition by 8-bit blocks from our experiment on ARM chip board with a register size of 32-bit. In total we required 9700 power traces to successfully recover the 128-bit secret key for the attack against.
