Abstract:
An information processing apparatus includes a volatile storage unit, nonvolatile storage unit, and control unit configured, in a case where a factor to shift the information processing apparatus to a state in which power supply to the volatile storage unit is stopped exists, to encrypt and store information, stored in a specific region in the volatile storage unit, in the nonvolatile storage unit, and to store, in the nonvolatile storage unit in unencrypted form, information stored in a region other than the specific region, and configured, in a case where a factor to shift the information processing apparatus to a state in which power is supplied to the volatile storage unit exists, to decrypt and store the encrypted information, stored in the nonvolatile storage unit, in the volatile storage unit, and to store, in the volatile storage unit, the unencrypted information stored in the nonvolatile storage unit.
