description An information processing device (10) acquires, from a security module storage unit (12d) with tamper resistance, a public key and ID information of the configuration file for verifying a digital signature for a configuration file, and uses the acquired public key and ID information to cause an application program (11) to execute processing of verifying the integrity of configuration data of the configuration file. Then, the information processing device (10) acquires registration version information from the security module storage unit (12d), and uses the acquired registration version information to cause the application program (11) to execute processing of verifying the configuration version of the configuration file. Further, the information processing device (10) updates the registration version information to the version of the configuration version when the configuration version of the configuration file and the registration version information satisfy a predetermined condition.
