Designation Definition
password, the function provided on the service screen can be used. Supports the TOE
installation and trouble.
User ID Identification to which the TOE identifies the user. If the user successfully logs in, it is
associated with the user attribute. For normal users and user administrators, the registered
No. of the user management function is assigned. Built-in administrator is assigned a
special fixed number.
Login Obtain credentials from users to perform identification and authentication, and if
identification and authentication is successful, make TOE available. This can be performed
from the operation panel, WC, and printer driver.
User name Identification entered as credential by the normal user and user administrator when logs in.
When MFP Device Authentication, the TOE identifies whether the user is a registered user
by user name. This is set when registering a normal user in the user management function
and cannot be changed thereafter.
Login password The password that the user enters as credential at login. When MFP Device
Authentication, the TOE authenticates the user by a login password. There are user
passwords, administrator passwords, and service passwords.
User password Login password for normal user. When MFP Device Authentication, the administrator can
set the user password for each normal user in the user management function. The normal
user can change his or her own user password.
Administrator password Login password for the built-in administrator. At the time of TOE shipment, the
predetermined administrator password is set, and the built-in administrator changes the
default value at the time of TOE installation. Thereafter, the administrator can change.
CE password Login password of the customer engineer.
Suspend temporarily Function that an administrator suspends the use of TOE by normal user. The administrator
can set and release the temporary suspension of use for each User ID registered in the user
management function. When a user who has a User ID with a Temporary Suspension is
logged in, the TOE discards the relevant user attribute and so user fails to log in and cannot
use the TOE.
Administrator Rights Function that an administrator allows the use of TOE by normal user in the role of
administrator. Administrator can set and release the administrator rights for each User ID
registered in the user management function. When a user who has a User ID set
administrator rights logs in successfully with the administrator authority, TOE can be
used in the role of administrator. When a user who has a User ID not set administrator
rights performs log in with the administrator authority, TOE discards the relevant user
attribute and so user fails to log in and cannot use the TOE.
Function Restriction Afunction that restricts the functions available to the normal user by the administrator. The
administrator can set or release the function restriction for each User ID registered in the
user management function. When a normal user with a User ID set a restricted function
performs a login, the TOE will hide the UI of the restricted function or display them with
the deactivate status and will not be able to use the restricted function.

FPT_TUD_EXT.1.2 The TSF shall provide authorized administrators the ability to initiate updates to TOE firmware/software.
FPT_TUD_EXT.1.3 The TSF shall provide a means to verify firmware/software updates to the TOE using a digital signature
mechanism and [selection: published hash, no other functions] prior to installing those updates.
Rationale:
Firmware/software is a form of TSF Data, and the Common Criteria does not provide a suitable SFR for the
management of firmware/software. In particular, there is no SFR defined for importing TSF Data.
This extended component protects the TOE, and it is therefore placed in the FPT class with a single component.

Identification and Authentication function
TOE acquires credentials from users, performs identification and authentication, and provides an identification and
authentication function, that allows to use TOE, only to those who are judged as authorized users as a result of
verification.
FIA_UAU.1, FIA_UID.1
TOE supports the three authentication methods shown in Table 7-2 and an administrator can set in the user
authentication setting function.
When using TOE from the operation panel or WC, enter the user name, user password, and administrator rights. When
using TOE from the operation panel or WC as the built-in administrator, enter the administrator password from the login
screen for the built-in administrator. When using TOE from the printer driver, enter the user name and user password.
TOE performs the identification and the authentication based on the input credentials, and permits the use of TOE only
if successful. If the external server authentication method is set, the user enters an external authentication server ID in
addition to the user name and user password. TOE sends the user name to the specified external authentication server and
decrypts the returned credential by user key generated from the user password. It determines that the authentication is
successful when the decryption is successful, and that the authentication is not successful when the decryption is failed.
Identification and authentication of Built-in Administrator is always performed by the MFP authentication method,
regardless of the authentication method setting.
TOE provides a function for the administrator to set the password to the Memory RX user box in the Memory RX
setting function, and Memory RX user box password has been set during operation. When a normal user who succeeds in
identification and authentication from the operation panel or WC accesses the Memory RX user box, authentication
using the Memory RX user box password is requested, and access is permitted only when authentication is successful.
Therefore, a normal user who does not know the Memory RX user box password cannot operate fax documents stored in
the Memory RX user box. The authentication of Memory RX user box password is always performed by the MFP
authentication method, regardless of the setting of the authentication method.
Since identification and authentication is performed for each of the above interfaces, the normal user can perform
identification and authentication from the panel while the administrator is performing the remote management function
from the WC, and if successful, the TOE can be operated. However, because identification and authentication of other

administrators is prohibited while an administrator logs in, two or more administrators cannot use TOE simultaneously
When TOE is used by the printer driver, there is no interactive session. When TOE receives electronic document,
identification and authentication is performed using the credential (user name, user password) included in the electronic
document. If successful, the normal user (U.NORMAL) is assigned as the user’s role and stored in TOE as an electronic
document owned by relevant normal user. If it fails, the received electronic document is destroyed without storing it. The
Printer Driver does not provide a way for administrators to use TOE.
Possible operations before performing identification and authentication are as follows.
・FAX RX
・The following settings can be used to check and display the TOE status.
 Device information display from the operation panel (firmware version etc.)
 Job display from the operation panel
 Enlarge display setting from the operation panel
Table 7-2 User Authentication Setting function
Authorization method Identification and authentication
MFP device authentication
TOE performs identification and authentication. Confirms that the user name and user
password or administrator password or Memory RX user box password match the
information registered in the TOE.
External server authentication
TOE performs identification and authentication by using the external authentication server
(Active Directory). TOE sends user name to the external authentication server specified by
user by using the Kerberos version 5 protocol, and decrypts the returned credential by the
user key generated from user password, and performs identification and authentication.
MFP device + External server
Authentication
TOE performs identification and authentication using either MFP device authentication or
external server authentication. The user selects the authentication method when logging in.

For each normal user registered with the user management function, TOE defines the User ID, administrator rights
and the access authority of function restriction as the user attribute. Also, the access authority to Memory RX user box is
defined as the user attribute, too. The authority to Memory RX user box is realized with the setting of Memory RX user
box password of Memory RX setting functions. Also, User ID is defined as user attributes of the built-in administrator.

・operation panel : User registration function by administrator
Memory RX user box password authentication setting function by administrator
FIA_USB.1
TOE associates the user attribute (User ID, administrator rights, function restriction, access authority to Memory RX
user box), if a normal user or a user administrator succeeds in identification and authentication. TOE associates the user
attribute (User ID), if the built-in administrator succeeds in identification and authentication.
At this time, TOE discards the user attribute associated with the user, if the temporary suspension is set to the User ID.
Also, if the administrator rights are not set to the user who performed the login as the user administrator, the user
attribute associated with the relevant user is discarded.
When accessing the memory RX user box after a normal user succeeds in identification and authentication, the
authentication by memory RX user box password is required. If the authentication is successful, TOE enables access to
the memory RX user box that is the user attribute of the relevant user. If the authentication fails, the TOE disables access
to the memory RX user box that is the user attribute of the relevant user.

FIA_AFL.1
The TOE provides an authentication operation prohibition function to stop the user's authentication when the
administrator detects a continuous authentication failure more than the number of checks (1 to 3 times) set in advance by
the administrator in the user's identification and authentication. If an administrator rights is assigned to a normal user, the
number of authentication failures as a normal user and the number of authentication failures as a user administrator are
totaled.
When the authentication of the built-in administrator was suspended, turn OFF and ON the TOE power first. Then, the
authentication suspension is released when the time set for the operation prohibition release time setting, has passed after
the TOE is started. If the authentication of the normal user or the user administrator is suspended, the administrator who
is not in the suspended status can release their suspension by performing the deletion function of the number of the
authentication failure.
The TOE also performs the above-mentioned authentication failure operation for identification and authentication by
an external server authentication method.
The authentication of the memory RX user box password is suspended when the administrator detects a continuous
authentication failure more than the number of checks (1 to 3 times) set in advance by the administrator in the
identification and authentication of memory RX user box password. If the authentication of memory RX user box
password is suspended, the administrator who is not in the suspended status can release the authentication suspension by
performing the deletion function of the number of authentication failures.

Access control function
FDP_ACC.1, FDP_ACF.1
The TOE restricts the operation of user document data and user job data as described in Tables 7-3 through 7-14, based
on the user data access control in Tables 6-2 and 6-3. For unauthorized operations, the interface is hidden or displayed in
an inoperable state, or a message is displayed indicating that the operation cannot be performed because there is no
authority on the operation request, and the operation is rejected.
When a normal user (U.NORAML) allowed by the identification and authentication performs Create operations in
Tables 7-3 through 7-14, the user becomes a Job Owner and TOE records the User ID as the owner information of a
document or Job. TOE does not provide an interface for an administrator (U.ADMIN) to perform a Create operation.
Since the Fax RX function (Fax receive) performs the Create operation by receiving a fax from an external fax without
the TOE operation, the job owner of the document or job until the Fax RX completion is assigned to the administrator
(*1). In the case of Fax RX with no F-code specified, the fax document is saved in the Memory RX user box, so the job
owner after the Fax RX is the normal user who knows the Memory RX user box password (*2). In the case of Fax RX
with the F-code specified, the fax document is saved in the specified personal user box, so the job owner after Fax RX is
the normal user who owns the personal user box (*3). Saving from the password encrypted PDF user box (Storage /
retrieval) is performed the create operation by retrieving the document, set to be saved, from the password encrypted
PDF user box and saving it in the operator's personal user box, when performing the direct print. The job owner of the
document or job after saving is the normal user who is the owner of the personal user box.
TOE has a function restriction setting that restricts the functions available to each normal user by the administrator in
the user management functions. The TOE displays the interface of the restricted function either hidden or inoperable
based on the user attribute function limitations. Therefore, a normal user with a function restriction cannot use the
operation using the restricted function from Table 7-3 to Table 7-14.
TOE has Memory RX setting function in which the administrator restricts the access of the normal user to the memory
RX user box in the Memory RX setting function. During operation, access is restricted by the memory RX user box
password. Based on the access authority to the memory RX user box of user attribute, the TOE allows access to the user's
memory RX user box if it is valid, and denies access to the user's memory RX user box if it is invalid. Therefore, normal
users who do not know the memory RX user box password cannot use the operations required to access the memory RX
user box in Tables 7-3 to 7-14.
In the user box management function, the TOE has a function to set the owner of the personal user box (User ID) by
the administrator or normal user. It has a function to change the owner of the personal user box (User ID) by the
administrator or the normal user who owns the personal user box. The TOE restricts access to the personal user box and
documents stored in the personal user box. If the normal user has the same User ID based on the Personal user Box
Owner (User ID), the TOE provides an interface to the Personal User Box and permits access to the Personal User Box.

On the other hand, if the normal user has a different User ID, the TOE will hide the interface of the relevant Personal
User Box, so the operation that requires the access to the relevant personal user box with Tables 7-3 to 7-14 cannot used.

FCS_RBG_EXT.1
TOE implements a CTR DRBG (AES-256) conforming to NIST SP 800-90A and an RBG consisting of a single
software entropy source. The above CTR DRBG uses the Derivation Function and Reseed, but the Prediction Resistance
function does not work. The software entropy source implements a condition branch code etc., that affects the internal
state of the CPU, and a clock counter value acquisition process in the loop process. The variation of the loop processing
performance time is acquired via the clock counter and obtain the raw data. Conditioning is performed to agitate and
compress the entropy included in the raw data into the entire bit using shift operations and XOR, and after increasing the
entropy rate of the entire bit, it is output as an entropy value.
The TOE uses this RBG to generate random numbers and uses them to generate encryption keys (key length 256 bit
and 128 bit) with a trusted communication function. When the TOE generates a random number, if the CTR DRBG
requires a seed material (Entropy Input and Nonce), start the software to be used as the entropy source and obtain and use
the required size entropy value. This entropy value satisfies the minimum amount of entropy required for Instantiate and
Reseed (in the case of TOE, 256 bits equal to the security strength) shown in 10.2.1 of NIST SP800-90A and contains
sufficient entropy.

Security Management function
FMT_MOF.1, FMT_MSA.1, FMT_MSA.3, FMT_MTD.1, FMT_SMF.1, FMT_SMR.1
TOE provides the following management functions to users. Each management function is operable only from the
interface described. The printer driver does not provide management functions. When transiting the screen of
performing the following management functions on the operation panel or WC, identification and authentication to TOE
is requested, and so the management function cannot be used without authentication. At login, associate roles
(U.ADMIN, U.NORMAL) with the user and maintain the associated roles until they are logged out. Cannot use the
management functions that are not provided in the user role. In the access control of Tables 6-2 and 6-3, TOE assigns the
User ID of the normal user who created the user document data and the user job data as the initial value of the security
attribute. User document data and user job data generated by the Fax RX function are created by users other than TOE.
Therefore, an administrator's User ID is assigned as the initial value of the security attribute, and the access control of
Fax receiving is performed. After Fax RX is completed, Fax document is stored in the Memory RX user box if F-code is
not specified, and it is controlled with the access authority of Memory RX user box and so the security attribute is not
related. Administrator’s User ID is assigned as the initial value. If Fax RX with F-code, specified personal user box’s
User ID is assigned as the initial value of security attributes. Refer to “ 7.2 Access control function” for details. TOE
does not have a function to overwrite the User ID assigned as the initial value.

FPT_SKP_EXT.1
TOE stores the pre-shared key set by the administrator and the private key of the IPsec certificate, among the
encryption keys used for IPsec communication in the SSD that is a Field- nonreplaceable non-volatile storage. Other
encryption keys are stored in RAM (see Table 7-15). The TOE does not provide the ability to view stored pre-shared
keys, private keys, and encryption keys, so users cannot retrieve them by operating the TOE. The TOE implements
RS-232C IF on the MFP itself, but since it is disabled during operation, the user cannot use this interface to retrieve SSD
internal data. Other than the RS-232C IF, the interface for retrieving SSD internal data from outside the TOE is not
implemented. Because SSD is the field-nonreplaceable storage, user cannot remove SSD and retrieve internal data.
Therefore, users cannot read the stored pre-shared key, private key, or encryption key.
Audit function
TOE generates and records an audit log for the event being audited and sends it to the log server.

set by the trusted communication management function.
The TOE temporarily saves log information as a log file in the local storage area of the TOE. It converts it to XML
data and sends it to the log server when the date and time set in the automatic log distribution condition or the log storage
amount set in the automatic log distribution condition is reached or when the administrator performs the audit log
transmission.
Log files temporarily saved in TOE are deleted after conversion to XML data or when an administrator performs the
audit log deletion. XML data is deleted at the timing of XML data conversion of the next file, after transmission to the
log server is completed. The only interfaces that access the log files and XML data stored temporarily in the TOE are the
sending and deletion of audit logs by the administrator, and so unauthorized access by normal users or attackers is not
possible.
When log information cannot be sent to the log server due to network failure, etc., and the local storage area in the
TOE becomes full, the functions that can be performed are limited to the following functions.
・End of the audit log acquisition function by turning OFF the power supply
・Start of the audit log acquisition function by turning ON the power
・User Authentication (only administrator login from the operation panel is allowed)
・Sending or deleting audit log by administrator
The restriction is released, by an administrator sends an audit log or performs an audit log deletion and clears the full of
the local storage area.
Table 7-20 Audit Log Data Specifications
Handling of audit log data Overview
Storage area of log information Store on the SSD
Size to hold log information
Log information is temporarily saved as a log file, converted to XML data, and
sent to the log server.
Log files can be saved up to 40 MB and converted to XML data for transmission
to the log server at any of the following timings. After conversion, the
corresponding log file is deleted.
・ When the date and time set by the administrator or the accumulated amount
are reached
・ Upon reaching 36 MB
・ When an administrator performs an audit log TX
XML data is deleted when the next XML data is generated after sending it to the
log server. If the transmission fails, a maximum of 76 MB (40 MB of log file, 36
MB of XML data) is temporarily stored in the TOE.

7.7.1. Update function
FPT_TUD_EXT.1
The administrator can confirm the firmware version on the administrator screen after the identification and
authentication from the operation panel or WC.
In addition, the administrator can install a USB memory storing firmware data and digital signature data in the TOE
and perform the firmware update function on the administrator screen after the identification and authentication on the
operation panel. Firmware data includes various firmware such as system controller and print controller, and hash value
information for each firmware calculated by SHA-256 (used for self-test function described in 7.7.2). Digital signature
data is data signed with the RSA digital signature algorithm (key length 2048 bit, signature scheme PKCS #1 Ver 1.5)
described in FIPS PUB 186-4, "Digital Signature Standard" for the hash value of firmware data calculated by SHA-256.
When the administrator performs the update function, the TOE verifies the digital signature of the firmware data by
using the RSA public key (key length 2048 bit, installed in TOE at the time of shipment) before starting the installation.
If the signature verification fails, a warning is displayed on the operation panel and firmware is not rewritten. If the
signature verification is successful, the firmware and the hash value information for each firmware is installed. The
procedures for digital signature verification are as follows.
Decrypt the digital signature data with the RSA public key (key length 2048 bit) owned by TOE.
Calculate the hash value of the firmware data by SHA-256.
Compare the values of (1) and (2). The firmware data is judged to be correct if the data are matched.
