• TPM (Trusted Platform Module) - TPM is a standard security chip (tamper
resistant hardware) installed in the imageRUNNER ADVANCE DX C5800
Series. The TPM provides a facility for the secure generation of cryptographic
keys, encrypts information stored on the internal SSD, and decrypts information
read from the internal SSD. 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 SSD is removed from the
machine, it may be difficult to retrieve data off that SSD 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
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 back up 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.
