Readers are reminded that the certification of this product (TOE) is the result of maintenance, rather than an actual re-evaluation of the product.  Maintenance only considers the affect of TOE changes on the assurance baseline (i.e. the original evaluated TOE); maintenance is not intended to provide assurance in regard to the resistance of the TOE to new vulnerabilities or attack methods discovered since the date of the initial certificate.  Such assurance can only be gained through re-evaluation. 

Using a security impact analysis of the changes made to the TOE, which was provided by the developer, the CCEVS has determined that the impact of changes on the TOE are considered minor and that independent evaluator analysis was not necessary.  A summary of the results can be found in the Maintenance Report, which is written in relation to the product's original validation report and Security Target.  Readers are therefore reminded to read the Security Target, Validation Report, and the Assurance Maintenance Report to fully understand the meaning of what a maintained certificate represents. 

Product Description

In the updated ST, version 1.1, Table 1 “Table 1: TOE Models and Firmware Versions”, was modified to show the 5 new firmware versions added to 14 CC certified hardware versions.   

There were 111 non-security relevant firmware changes associated with this Assurance Continuity update. There were no changes to the TSF Hardware, to the Development Environment, or to the Security Functions. The table below is an accounting of the firmware changes made to support the new versions of firmware. It is divided into the sub-categories: New Features and Feature Enhancements, Performance Improvements, and Bug Fixes. Detailed information regarding each of the firmware changes is provided in the IAR. None of the code changes are security relevant.


Number of Changes

Applicability to New Firmware Versions

New Features and Feature Enhancements


There were no new Features, and the seven Feature Enhancements were included in all the new firmware versions.

Performance Improvements


All 13 Performance Improvements were included in all the new firmware versions.

Bug Fixes


90 Bug Fixes were included in all new firmware versions.  There was an error logging fix that was only included in firmware versions SF02 and TF02.


The code changes did not impact the crypto software and, therefore, did not require update to the CAVP certificates. There were no changes to the EAR except to add the new hardware firmware versions.
