Abstract
A terminal that performs secure boot processing when booting, thereby booting reliably even if, during updating of a software module, the power is cut off or the update is otherwise interrupted. The terminal comprises a CPU, a software module storage unit, a certificate storage unit, an updating unit for updating the software module and certificate, a security device provided with a configuration information storage unit for storing the configuration information of the software module, an alternate configuration information storage unit for storing the configuration information of a software module in the configuration before the update, and a boot control unit for verifying and executing the software module by using the certificate. The terminal verifies the certificate of the software module by comparing the configuration information stored by the configuration information storage unit with the configuration information stored by the alternate configuration information storage unit.
