• TPM (Trusted Platform Module) (Standard) – The TPM (tamper resistant
hardware) provides a facility for the secure generation of cryptographic keys,
encrypts information stored on the internal storage drive, and decrypts
information read from the internal storage drive. The public keys to encrypt
confidential information are securely controlled by the TPM chip, and they can
only be decrypted if the TPM releases the associated decryption key. If the
storage drive is removed from the machine, it may be difficult to retrieve data off
that storage drive since the encryption key for that data is stored in a separate
location within the TPM.
CAUTION
Once the TPM setting is activated, if the end user fails to back up the TPM
key, or if the end user loses the TPM key, it may result in permanent,
unrecoverable data loss, for which Canon U.S.A., Inc. is not liable. (See
page 6 for further details.)
IMPORTANT
• If the TPM setting is activated and the TPM chip fails, the confidential
information stored on the chip can only be recovered if Canon's service
representative replaces the TPM chip and restores the original TPM key to the
new chip. Immediately, back up the TPM key on a USB memory stick, after the
TPM setting is activated.
• Only the Administrator of the machine can back up the TPM key.
• For security reasons, the TPM key can only be backed up once. Store the USB
memory with the backup data in a safe place.
• For the backup of the TPM key, it is recommended that a USB memory stick
(supported system file: FAT32) with free space of 10 MB or more is used.
• The TPM seals the hardware components associated with the data, and the
data cannot be accessed unless the specific TPM key is issued by the TPM
chip. Therefore, setting the TPM mode to 'On', may affect service procedures
and service costs (if not handled properly). It is strongly recommended that the
Administrator who has access to the TPM key be present for all service calls to
prevent the loss of data and productivity of the machine.
