Abstract
(EN)
Disclosed is a cryptogram calculation method. The cryptogram calculation method comprises the steps of: receiving a comparative calculation command for a plurality of cryptograms of the same type; performing a calculation by reflecting the plurality of cryptograms of the same type on a synthesis function corresponding to the comparative calculation command; and outputting the calculated cryptograms of the same type.

L'invention concerne un procédé de calcul de cryptogramme. Le procédé de calcul de cryptogramme comprend les étapes consistant à : recevoir une commande de calcul comparative pour une pluralité de cryptogrammes du même type ; effectuer un calcul en reflétant la pluralité de cryptogrammes du même type sur une fonction de synthèse correspondant à la commande de calcul comparative ; et délivrer en sortie les cryptogrammes calculés du même type.
