Case Study: A COTS Approach to Data-at-Rest Encryption Onboard an Unmanned Underwater Vehicle (UUV)

Version 1

    Data-at-Rest-Encryption-Onboard-UUV.GIFLooking for a network attached storage (NAS) device for an unmanned underwater vehicle (UUV), a system developer contacted Curtiss-Wright. Due to the size, weight and power (SWaP) constraints of the vehicle, the NAS needed to be very small while providing the network services of a larger file server. This aggressive approach to SWaP would extend the UUV mission length by propelling less mass through the water, free up space for other sensing or computing equipment and enable the vehicle’s power plant to last longer and go further.


    In addition to reducing the physical size and weight of the NAS, implementing remote boot of the network clients would provide an added SWaP optimization opportunity. Successful remote boot would eliminate the need for each network client to have independent storage. With over a dozen network clients on board, each with its own OS and unique application allowing it to perform its system function, the removal of a storage drive from each client could significantly reduce SWaP.


    Since the UUV could be lost during deployment, the developer (and their end customer) required that the data be protected to national standards. For data encryption, the choices included Type 1 devices or commercial encryption methods, but either solution must meet NSA approval.


    With an accelerated deployment schedule, the choices were limited to what could be accomplished without a long RFI/RFP and development process. The program could not afford schedule delays due to an encryptor development schedule and nor could they afford NRE investment.
