Abstract

An information processing device includes a memory, and processing circuitry coupled to the memory and configured to acquire, from a storage of a security module with tamper resistance, information related to a verification key and ID information of the configuration file for verifying a digital signature for a configuration file, and use the acquired information related to the verification key and ID information to cause an application program to execute processing of verifying integrity of configuration data of the configuration file, acquire registration version information from the storage of the security module, and use the acquired registration version information to cause the application program to execute processing of verifying a configuration version of the configuration file, and update 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.
