Abstract

L'invention porte sur une méthode d'élaboration d'une clef de codage et d'un identificateur public de puce consistant à appliquer une première fonction de hachage à sens unique à la valeur d'un identificateur de puce pour obtenir la clef de codage, puis à appliquer une deuxième fonction de hachage à sens unique pour obtenir l'identificateur public de puce.
