Title (EN) KEY PROCESSING METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE TRAITEMENT DE CLÉ
Abstract:
(EN) An attack on an RSA encryption algorithm based on simple power analysis (SPA) is thwarted by scrambling the sliding window sequence that results from performing sliding window processing on a power exponent. The sliding window sequence is scrambled with a random code that is utilized to determine an adjustment tendency and an adjustment length.
(FR) Une attaque sur un algorithme de chiffrement RSA basé sur une analyse de puissance simple (SPA) est déclenchée par le brouillage de la séquence de fenêtre glissante qui résulte de la réalisation d'un traitement de fenêtre glissante sur un exposant de puissance. La séquence de fenêtre glissante est brouillée avec un code aléatoire qui est utilisé pour déterminer une tendance d'ajustement et une longueur d'ajustement.
