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. An information processing terminal (10) has first sealed data (310, 320, 330) respectively having usability conditions (312, 322, 332) of matching with predetermined terminal environment information during a secure boot and second sealed data (340, 350, 360) respectively having usability conditions (342, 352, 362) of matching with terminal environment information upon completion of the secure boot. Upon completion of the secure boot, the second sealed data is unsealed and the first sealed data is resealed using the unsealed data (341, 351, 361).
