INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND COMPUTER PROGRAM AND INTEGRATED CIRCUIT FOR THE REALIZATION THEREOF

摘要

Provided is an information processing device capable of continuously performing secure boots across module groups provided by a plurality of providers and maintaining independence between the providers. A collaboration certificate which includes a first configuration matching value (503) which indicates the cumulative hash value of a first module group performing a secure boot and a module measurement value (505) which indicates the hash value of the first module of a second module group performing a secure boot is provided. After the secure boot of the first module group, the starting of the first module group is verified by matching the first configuration matching value (503). Furthermore, when the first module of the second module group verified to be complete by matching the module measurement value (505) is started, a secure boot of the second module group is performed, and a module in the first module group was updated, a collaboration certificate update unit (135) updates the collaboration certificate.
