There are following differences between the configuration of the independent
testing and the TOE configuration identified in the ST. The evaluator determined
that there are no problems with those differences and that the security functions of
the TOE configuration identified in the ST can be considered properly tested.
(1) Tested models
In the models of the TOE described in Chapter 2 "TOE identification," there are
multiple models due to the following differences:
- Difference in the model name by sales area
- Differences in PDL Configurations (Standard or Optional)
- Difference in printing speed
- Difference in display language
The evaluator determined that the security functions of all the models of the TOE
can be considered to have been tested by testing the representative two models
considering the above differences, because the security functions of each models are
the same.
It should be noted that models with different names by sales area are the same
model, only the names in terms of product sales are different.
(2) Using a modified firmware for testing
In the independent testing, a firmware modified for testing was used to confirm the
encryption functions and input-output data of SSD instead of the firmware of the
TOE. The evaluator determined that the testing on the modified firmware is valid
because the modification for testing does not affect the functions of the test target.
(3) Using additional testing tools
In the independent testing, some testing tools were used to confirm and alter the
communication data and to confirm the encryption functions.
The validity of those testing tools was confirmed by the evaluator.
Summary of the Independent Testing
A summary of the independent testing is as follows.

a. Viewpoints of the Independent Testing
The viewpoints of the independent testing devised by the evaluator based on the
requirements of the Conformance PP and on the evaluation documentation
submitted for evaluation are shown below.
<Independent Testing Viewpoints>
(1) Confirm security functions for each Security Functional Requirement (SFR).
(2) Confirm that the implementation of the cryptographic algorithms is correct.
b. Independent Testing Outline
An outline of the independent testing that the evaluators performed is as follows.
<Independent Testing Approach>
The behavior of the TOE for inputs using the control panel of the TOE, the
client PC and the testing tools was confirmed by following means:
- If the behavior can be confirmed from the external interfaces of the TOE, the
external interfaces of the TOE including audit logs are used.
- If the behavior cannot be confirmed from the external interfaces of the TOE,
the developer interface of the TOE is used.
