Title (EN) CRYPTOGRAPHIC DEVICE AND METHOD
(FR) DISPOSITIF ET PROCÉDÉ CRYPTOGRAPHIQUES
Abstract:
(EN) Some embodiments are directed to an electronic cryptographic device arranged to perform a cryptographic operation on input data obtaining output data. The cryptographic device stores an internal state as sets of shares. Fourier coefficients corresponding to the sets of shares satisfy a predetermined relationship among them. The cryptographic operation is performed by repeatedly updating the internal state.
(FR) Certains modes de réalisation concernent un dispositif cryptographique électronique conçu pour effectuer une opération cryptographique sur des données d'entrée pour obtenir des données de sortie. Le dispositif cryptographique stocke un état interne sous la forme d'ensembles de parts. Des coefficients de Fourier correspondant aux ensembles de parts satisfont à une relation prédéterminée entre eux. L'opération cryptographique est effectuée par la mise à jour répétée de l'état interne.
