Abstract
Side Channel Attacks (SCA) are one of the most effective means in breaking symmetric key ciphers. Generally, SCA exploits the side-channel leakages output by the implementations of ciphers or introduces defects in the system to analyze them. A number of countermeasures have been proposed to strengthen/remedy implementations of ciphers against SCA. However, none of the countermeasures, to our knowledge, are good enough towards its goal ([16], [19], [3]). In this paper, we emphasis on the necessity of randomness in designing countermeasures against SCA and propose Cellular Automata (CA) based system to thwart SCA. Our countermeasure is also analyzed against popular SCA, such as, differential power attack (DPA), scan-chain based attacks (SC-SCA) and fault attacks (FA). © 2012 Springer-Verlag Berlin Heidelberg.
