Administrator Operations 2
2.8 Protecting Data in the HDD
When access by the Administrator of the machine from the control panel through the Admin. Settings is
authenticated, the machine enables the operation for setting and changing the HDD Lock Password. If the
machine is equipped with the optional Security Kit SC-503, it enables the operation for setting and changing
the Encryption Key and the operation for setting the Overwrite Priority Setting function.
Should the HDD be removed unawares, the HDD Lock Password locks the HDD protecting data contained
in the HDD. Furthermore, by setting the Encryption Key, the data stored in the HDD is encrypted, thereby
protecting the data in the HDD. The HDD Lock Password and Encryption Key entered are displayed as "*."
The Overwrite Priority Setting function allows the setting of either "Encrypt Priority" or "OverwritePriority."
The default setting is "Encrypt Priority."
For details, see the table below.

Note
Do not set any number that can easily be guessed from birthdays, employee identification numbers,
and the like for the HDD Lock Password and Encryption Key. Try to change the password at regular
intervals.
Make sure that nobody but the Administrator of the machine comes to know the HDD Lock Password
or Encryption Key.
If only the Encryption Key is to be set while the machine is being used without setting the HDD Lock
Password or Encryption Key, the Service Engineer must perform some setting procedures in advance.
For more details, ask the Service Representative.

Reminder
When the HDD Lock Password is set, HDD verification is carried out when the machine is started. If the
HDD has been improperly replaced with another, or if the HDD Lock Password is yet to be set, a
message appears that tells that there is a mismatch between the HDD and the HDD Lock Password.
Further, the HDD has the following function. That is, if the HDD is illegally removed or replaced with
another, detection of a wrong HDD Lock Password five consecutive times will lock the authentication
function. Leak of data can thus be prevented.
When an Encryption Key (encryption word) is set using HDD Encryption Setting, an Encryption Key with
a key length of 128 bits is generated using the SHA-1 algorithm. The generated encryption key is used
to encrypt or decrypt data through AES encryption algorithm.
When the Encryption Key (encryption word) is set with the optional Security Kit SC-503 mounted on the
machine, the encryption strength can be selected from among [Encrypt Priority] or [OverwritePriority].
For more details, see
"Setting the Encryption Key (encryption word)" on page 2-27 ".
Mode Description
Encrypt Priority In addition, writing is performed by enhancing strength of encryption of the data written in the
HDD.
Select this function if a greater effect of encryption is desired.
OverwritePriority The standard scheme is, however, applied to encryption of data to be written in the HDD.
Select this function if an overwrite and delete operation that complies with the HDD data erasure
standard is desired.
