<p>A secure device comprises a data exchange card application carrying out data exchange between card applications isolated by a fire wall, card application plug-in data defining authentication processing of the data exchange card application, in such a manner that authentication processing between the card application and the data exchange card application is carried out in the same manner as authentication processing between the card application and a dedicated host terminal, and authentication key data used for this authentication processing. Data exchange and tie-up processing between card applications are possible in a secure device, or under the mediation of a mobile terminal, and rapid processing can be done. The card application has only to carry out the same operation as data exchange with a related dedicated host terminal. Also, tie-up processing between card applications can be carried out by only a mobile terminal side in which a secure device is loaded. <IMAGE></p> |
