Upon completion of the secure boot, the second sealed data is unsealed and the first sealed data is resealed using the unsealed data. It is possible to update and re-seal sealed data having a usability condition of matching with predetermined terminal environment information during a secure boot without rebooting a terminal when a program using the sealed data is updated.
