摘要:
The present invention provides an information processing apparatus that is capable of continuously performing secure boot between module groups in the case where software of a terminal device consists of module groups provided by a plurality of providers, while keeping independence between the providers. The information processing apparatus is provided with a linkage certificate that contains a first configuration comparison value 503, which indicates a cumulative hash value of the first module group to be started up by secure boot, and a module measurement value 505, which indicates a hash value of the first module of the second module group to be started up by secure boot. After the secure boot of the first module group, it is verified that the first module group has been started up by comparison with the first configuration comparison value 503. Then, the second module group is started up by secure boot by starting up the first module of the second module group whose completeness has been verified by comparison with the module measurement value 505. When a module of the first module group is updated, the linkage certificate update unit 135 updates the linkage certificate.
