Abstract

L’invention concerne un procédé de génération d’encodage pour algorithme cryptographique, mis en œuvre par ordinateur. On y met en œuvre les étapes suivantes : - obtention d’au moins une caractéristique propre à un périphérique informatique (1) configuré pour exécuter un algorithme cryptographique (43) ; - à partir de la caractéristique propre, génération d’une opération d’encodage (433, 434) dépendante du périphérique (1); - association de l’opération d’encodage dépendante (433, 434) générée à l’algorithme cryptographique (43). Figure pour l’abrégé : figure 2
