Abstract

Very few solutions are known to protect the modular exponentiation for single-chip devices against simple power analysis (SPA) attacks. In this paper, we present a model approach to address the power analysis problem. Using the model approach, we propose a modular exponentiation algorithm, which is secure under the SPA model. Compared with the known solutions, the proposed algorithm is more suitable for real-life applications .
