Patent ID: 8438377

Claim:
An information processing apparatus comprising: a storage unit that retains contents stored therein; a control unit that performs hibernation of generating operating-state data that indicates an operating state of the information processing apparatus when the information processing apparatus is powered off to store the operating-state data in the storage unit, and reading the operating-state data from the storage unit to restore the information processing apparatus to the operating state when the information processing apparatus is powered on; a security chip that encrypts data based on a value calculated from the generated operating-state data when the information processing apparatus is powered off, and decrypts the encrypted data based on a value calculated from the read operating-state data when the information processing apparatus is powered on; and a verification unit that performs verification at boot-up from the hibernation by determining whether to permit decryption of the data based on the value calculated from the read operating-state data when the information processing apparatus is powered on.
