The Curtiss-Wright Defense Solutions Data Transport System 1-Slot Hardware Layer (hereafter referred to as the TOE) is a hardware encryption layer that is used for Data-At-Rest (DAR) encryption as part of the underlying rugged Network Attached Storage (NAS) file server, denoted as the Curtiss-Wright DTS1 CSFC/ECC Cryptographic Data Transport System (DTS) (hereafter referred to as the DTS1). The underlying DTS1 is intended for use in Unmanned Aerial Vehicles (UAV), Unmanned Underwater Vehicles (UUV), and Intelligence Surveillance Reconnaissance (ISR) aircraft.  Easily integrated into network centric systems, the DTS1 is an easy to use, turnkey, rugged network File Server that houses one Removable Memory Cartridge (RMC) that provides quick off load of data. The RMC can be easily removed from one DTS1 and installed into any other DTS1 providing full, seamless data transfer between one or more networks in separate locations (e.g. ground => vehicle => ground).  In addition to the software-based FDE layer provided by the DTS1 (see the separate ST corresponding to that evaluation), the DTS1 provides a hardware-based Full Drive Encryption (FDE) layer to encrypt the drive within the RMC.

The evaluation was carried out in accordance to the Common Criteria Evaluation and Validation Scheme (CCEVS) requirements and guidance.  The criteria against which the TOE was judged are described in the Common Criteria for Information Technology Security Evaluation, Version 3.1, Revision 5, September 2017. The evaluation methodology used by the evaluation team to conduct the evaluation is the Common Methodology for Information Technology Security Evaluation, Evaluation Methodology, Version 3.1, Revision 5, July 2017.    The product, when delivered and configured as identified in the Curtiss-Wright DTS1 CSfC 1-Slot Data Transport System (CSfC) User Guide, DOC0099-000-B4 document, satisfies all of the security functional requirements stated in the Curtiss-Wright Defense Solutions Data Transport System 1-Slot Hardware Encryption Layer version 5.4 Security Target, Version 1.7, March 21, 2023.  The project underwent CCEVS Validator review.  The evaluation was completed in March 2023.  Results of the evaluation can be found in the Common Criteria Evaluation and Validation Scheme Validation Report prepared by CCEVS.

Protection of the TSF:

The TOE implements a number of features to protect itself to ensure the reliability and integrity of its security features. It protects key and key material, and includes functions to perform self-tests and software/firmware integrity checking so that it might detect when it is failing or may be corrupt.If any of the self-tests fails, the TOE will not go into an operational mode
