<p>The loading of a plurality of applications into a chip card is organized in a different way by creating a set of tables, essentially four tables. A first table called the application table allows to create fundamental couples between names of applications and secrete codes, such table being in principle recorded once for all, already at the chip card manufacturer. A second table modifiable as desired, called data table, allows for each application to create as many data tables as desired. A third table called the table of rights allows to grant, by an application, and on data tables created by said application, specific rights associated to utilizations. A fourth table containing keys attached to an application allows to implement the ciphering fonction. In this way, a utilization is prevented from modifying or reading information recorded in the chip card, as for another application. The invention has the advantage with respect to the prior art to be more flexible and to introduce a subsequent modification.</p> |
