Abstract:
An information processing device verifies the authorization of an application that has issued an access request to access a device. When an application on a universal OS issues a processing request to a secure device driver, a secure VMM and an application identification unit on a management dedicated OS lock a page table of the application and refer to the page table to generate a hash value. The application is determined to be authorized or unauthorized by comparing the generated hash value with a reference hash value.
