Abstract:
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, which indicates a cumulative hash value of the first module group to be started up by secure boot, and a module measurement value, 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.
