Abstract

ON DECRIT UN SYSTEME POUR ASSURER LA SECURITE D'UN DISPOSITIF CONTRE LES FRAUDES PAR INTRUSION ET SANS INTRUSION, CE DISPOSITIF ETANT UNE IMPRIMANTE 17 POUR UTILISATION DANS UN SYSTEME D'IMPRESSION DE VALEURS, TEL QU'UN SYSTEME D'EXPEDITION DU COURRIER. LESYSTEME COMPREND UN MICRO-ORDINATEUR DE DECRYPTAGE DE LA DONNEE D'ENTREE DEVANT ETRE IMPRIMEE EN CONFORMITE AVEC UNE CLEF VALABLE DE CHIFFRAGE, LA DONNEE CRYPTEE ET LA CLEF ETANT FOURNIES PAR UN AUTRE DISPOSITIF, PAR EXEMPLE PAR UN APPAREIL D'AFFRANCHISSEMENT 1. LA CLEF DE CHIFFRAGE EST STOCKEE DANS UNE MEMOIRE ANTI-FRAUDE POUVANT ETRE COUPLEE AU MICRO-ORDINATEUR POUR LUI FOURNIR LA CLEF. DE PLUS, LA MEMOIRE COMPORTE UN FIL DE FAIBLE SECTION DE FACON QUE LA PRESENCE DE CE FIL PUISSE DEFINIR UNE PARTIE DE LA CLEF DE CHIFFRAGE. POUR ASSURER ENCORE LA SECURITE CONTRE LES FRAUDES DU MICRO-ORDINATEUR, LA MEMOIRE ET LE FIL SONT NOYES DANS UN MATERIAU D'ENROBAGE. TOUTE TENTATIVE D'ENLEVEMENT DE CE MATERIAU POUR AVOIR ACCES AUX COMPOSANTS DANS LEQUEL ILS SONT NOYES PROVOQUERA LA RUPTURE DU FIL, CE QUI INVALIDERA LA CLEF DE CHIFFRAGE ET RENDRA LE MICRO-ORDINATEUR INOPERANT POUR DECRYPTER LA DONNEE A IMPRIMER.
