Secure boot terminal, secure boot method, secure boot program, recording medium, and integrated circuit
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.
Abstract(Chinese):

在启动时执行安全引导处理的终端，即使在更新软件模块期间断电或更新被中断的情况下也可以可靠地引导。 终端包括CPU，软件模块存储单元，证书存储单元，用于更新软件模块和证书的更新单元，设置有用于存储软件模块的配置信息的配置信息存储单元的安全设备， 配置信息存储单元，用于存储在更新之前的配置中的软件模块的配置信息;以及引导控制单元，用于通过使用证书来验证和执行软件模块。 终端通过将由配置信息存储单元存储的配置信息与备用配置信息存储单元存储的配置信息进行比较来验证软件模块的证书。
