Abstract:
An information processing apparatus includes a storage device configured to store data, an encryption chip configured to store an encryption key therein, a nonvolatile memory configured to store a backup encryption key, and a control unit configured to confirm whether the data stored in the storage device has been correctly decrypted by using the encryption key, and when the data has not been correctly decrypted, restore the backup encryption key to the encryption chip, and when the data has been correctly decrypted, back up the backup encryption key, which is a backup of the encryption key, stored in the encryption chip into the nonvolatile memory.

Claim (Index 1):
An information processing apparatus comprising:\n a storage device configured to store data; an encryption chip mounted on a first board of the information processing apparatus, and configured to store an encryption key therein, the encryption chip encrypting data to be written into the storage device by using the encryption key, and decrypting data read from the storage device by using the encryption key; a nonvolatile memory mounted on a second board, and configured to store a backup encryption key; and a control unit configured to confirm whether the data stored in the storage device has been correctly decrypted by using the encryption key, and when the data has not been correctly decrypted, restore the backup encryption key to the encryption chip, and when the data has been correctly decrypted, back up the backup encryption key into the nonvolatile memory.
