2.1 The problem with security in paying with chip cards is the loading of
input data into an
algorithm during authentication.
2.2 Separating the data blocks and switching; an additional feedback after the
post-connected
counters on and off at preselected times (number of clock pulses) helps to
improve the security
of debited and credited data.
2.3 The invention can be used for all authentication procedures where chip
cards are used.
La question de la sécurité des données dans les opérations de paiement à l'aide de cartes à puce est inhérente aux processus intervenant lors du chargement de données d'entrée dans un algorithme pendant la procédure d'authentification. Pour améliorer la sécurité des données de débit et de crédit, il est prévu une répartition des blocs de données et la connexion et la déconnexion d'une rétroaction après les compteurs intercalés à la suite à des périodes (cycles) prédéfinis. Cette invention peut s'utiliser dans toutes les procédures d'utilisation impliquant l'emploi de cartes à puce.
