METHOD AND APPARATUS FOR IMPLEMENTING ELLIPTIC CURVE CRYPTOSYSTEM RESISTING AGAINST SIMPLE POWER ATTACKS

摘要

PURPOSE: A method and an apparatus for implementing an ellipse curve encryption algorithm resistive to simple power attacks(SPA) are provided to increase the speed during the implementation of the structure resistive to SPA. CONSTITUTION: A method for implementing an ellipse curve encryption algorithm resistive to simple power attacks(SPA) includes the steps of: outputting the first multiple number operator as a second multiple number operator; operating the multiple number by the first multiple number operator; and adding the first summation operator to the second multiple number operator and outputting the adding result as a second summation operator.
