<P>PROBLEM TO BE SOLVED: To solve the problem that the application cannot use local resources of the terminal, since there is a possibility that an operation downloaded to a terminal 100 performs an invalid operation, the operation of the application is rigidly restricted. <P>SOLUTION: Authentication of the place of origin and whether or not tampering has not been carried out is confirmed, by carrying out authentication of the application downloaded to a downloading part 102 of the terminal 100, using the information for application confirmation retained in an tampering resistant range of an authentication module 101. By only permitting the use of the local resource by the terminal 100 or the authentication module 101 for the authenticated application, the use of the local resource by an invalid application can be prevented. Furthermore, since it is not necessary to provide the tampering-resistant resion to the terminal, manufacturing cost of the terminal can be kept at a low level. <P>COPYRIGHT: (C)2003,JPO |
