HDD Encryption Kit (Optional)
This option enables to generate the encryption key inside the encryption board and to
encrypt the whole HDD including the system software. Performing encryption can protect the
temporary image data generated at copying or printing, the registration information of the
Address Book and the password information from leakage of confidential information by theft
of the HDD.
Caution:
There is no need to reinstall the system in the case of installing the HDD Encryption Kit.
This is because the system is not deleted but stored in the flash memory.
●
HDD encryption function
Temporary image data such as scanned image or PDL data is written in the HDD of the host
machine on an as-needed basis. In normal operation, only the management information
is deleted after printing is complete or the file is deleted; therefore, the image or the user
file information remain in the HDD as they are (without modification). In this case, HDD
encryption function prevents an original image being restored from pulling out the HDD and
analyzing in disk editor.
●
Data encryption mechanism
The encryption board receives signals transmitted from the controller board, and encrypts
and saves them in the HDD.
The encryption board receives the encrypted data saved in the HDD to decode and send
them to the controller.
●
Conditions for Encryption Board operation
The encryption board has the function to recognize and authenticate the host machine. An
error is triggered if a second-hand HDD encryption/ mirroring board is installed to the other
machine.
●
Compatibility among Device, Encryption Board and HDD
E602-2000 error may occur if the unmatched authentication information is found between the
controller and the HDD encryption board and the encryption board is mounted.The device,
the encryption board and HDD can be connected in 4 use cases.
The following shows the statuses for each use case.
Case 1: Normally operated
Case 2: HDD-related error occurs because the system on the HDD cannot be read
(other than E602-2000 error)
Case 3: E602-2000 is triggered by failure in mutual authentication
Case 4: Unable to decode properly due to unmatched key for the encryption board
