| Abstract(in English) | Side channel attacks (SCA) are great threats for implementation of cryptographic schemes on smart cards. Although a lot of countermeasures have been proposed, the security of these countermeasures cause much controversy - some of them were attacked by the sophisticated newer attacks. Towards the provably secure SCA-resistant scheme, clavier-Joye proposed an exponent splitting countermeasure. In this paper we extend the exponent splitting to a scheme using the k-out-of-n threshold secret sharing scheme ((k, n)-TSSS), and propose four novel countermeasures. |
