| Abstract(in English) | A lot of side channel attack methods and countermeasures have been studied for modular powering based cryptosystems such as RSA. Conventional Chosen-Message Simple Power Analytical Attacks are very effective, but designed with respect to the modular powering operations. In this paper, we propose Chosen-Message Attacks focused on operands for multiple-precision multiplication to implement RSA. We devise novel chosen messages highly effective for such attacks and point out the vulnerability of multiplication algorithms. In addition we suggest a direction of improvement the attack methods by using some distinguished messages. |
