1. A secure device comprising:

  • a storage that stores predetermined data;

    an application storage that stores an application to be processed by an information processing terminal to obtain the predetermined data from the secure device, an information processing terminal obtaining the predetermined data from the secure device by executing the application at the information processing terminal, the information processing terminal not having the application for obtaining the predetermined data from the secure device;

    an application issuer that, upon receipt of a request from the information terminal, embeds in the application, as information for an authentication of said application, authentication information which is generated by the secure device on a random basis so as to have a varying value upon every issue of said application;

    an application transmitter that transmits, to said information processing terminal, said application in which said information for said authentication of said application is embedded by the secure device and having the varying value upon every issue of said application;

    an authenticator that, upon every issue of said application, performs with said information processing terminal an authentication process for said application executed on said information processing terminal, using said information for said authentication of said application embedded in said application, thereby obtaining a different authentication result upon every issue of said application; and

    a communicator that transmits to said information processing terminal said predetermined data stored in said storage, when said application executed on said information processing terminal is authenticated.
