Abstract: A disclosed encryption key restoring method enables restoration of an encryption key in the event of inability to use the encryption key stored in a secure memory of an information processing apparatus, in which data encrypted by the encryption key is stored in an internal storage unit. A disclosed information processing apparatus includes a key management module that checks the validity of the encryption key. If the encryption key is not valid, the key management module acquires a restore key for the encryption key from outside the information processing apparatus, and checks the validity of the restore key. If the restore key is valid, the key management module stores it in the secure memory, and reboots the information processing apparatus in a normal mode.
