### Paper: A comb method to render ECC resistant against Side Channel Attacks

Authors: Mustapha Hedabou Pierre Pinel Lucien B?n?teau URL: http://eprint.iacr.org/2004/342 Search ePrint Search Google Side Channel Attacks may exploit leakage information to break cryptosystems on smard card devices. In this paper we present a new SCA-resistant elliptic curve scalar multiplication algorithm, based on the Lim and Lee technique. The proposed algorithm builds a sequence of bit-strings representing the scalar $k$, characterized by the fact that all bit-strings are different from zero; this property will ensure a uniform computation behaviour for the algorithm, and thus will make it secure against SPA (Simple Power Analysis) attacks. The use of a recently introduced randomization technique achieves the security of the proposed scheme against other SCA attacks. Furthermore, the proposed countermeasures do not penalize the computation time
