Title (EN) APPARATUS AND METHOD FOR PERFORMING OPERATION BEING SECURE AGAINST SIDE CHANNEL ATTACK
(FR) APPAREIL ET PROCÉDÉ POUR EFFECTUER UNE OPÉRATION SÉCURISÉE CONTRE UNE ATTAQUE DE CANAL LATÉRAL
Abstract:
(EN) An apparatus and method for performing operation being secure against side channel attack are provided. The apparatus and method generate values equal to values obtained through an exponentiation operation or a scalar multiplication operation of a point using values extracted from previously generated parameter candidate value sets and an operation secure against side-channel attack, thereby improving security against side-channel attack without degrading performance.
(FR) L'invention concerne un appareil et un procédé pour effectuer une opération sécurisée contre une attaque de canal latéral. L'appareil et le procédé génèrent des valeurs égales à des valeurs obtenues par une opération d'exponentiation ou une opération de multiplication scalaire d'un point à l'aide de valeurs extraites à partir d'ensembles de valeurs candidates de paramètres générés précédemment et d'une opération sécurisée contre une attaque de canal latéral, ce qui permet d'améliorer la sécurité contre une attaque de canal latéral sans dégrader les performances.
