Curtiss-Wright introduces system to protect data on unmanned platforms

12 December 2018

Curtiss-Wright has developed a new network attached storage (NAS) system that incorporates Top Secret/Sensitive Compartmented Information encryption to protect critical data-at-rest (DAR) on unmanned deployed platforms.

"As the number of sensors on unmanned intelligence, surveillance, and reconnaissance platforms continues to proliferate, the challenge of protecting the critical data collected and stored on those platforms has grown in significance," Curtiss-Wright said.Curtiss-Wright's UNS system prevents unauthorised access to classified information stored on unmanned systems.

By using a DAR Type-1 encryptor Curtiss-Wright's Unattended Network Storage (UNS) system provides an off-the-shelf solution to prevent unauthorised access to classified information in the event that an unmanned system is lost or stolen, the company said.

UNS combines a data transfer rate of less than 2 GB/s with 32 TB of encrypted data storage on a Removable Storage Module (RSM). The RSMs ease the transport of DAR between unmanned platforms and base stations for post-mission analysis, Curtiss-Wright said.

The UNS chassis is designed to accept one removeable memory module. The RSM houses multiple 6.35 cm solid-state drives and supports Serial AT Attachment (SATA) III protocol that is capable of handling speeds of 6 Gb/s.

The DAR Type-1 encryptor uses Pre-Placed Keys, which enables the same key to be loaded onto multiple encryptors so that data can be encrypted onto an RSM in one location for decrypting later at another location.

The UNS's network interfaces include 4 x 10 Gigabit Ethernet (10 GbE) ports and 8 x 1 GbE ports. It supports industry-standard network storage protocols (such as Internet Small Computer Systems Interface, Network File System, HTTP, and FTP). It also supports remote client booting via Pre-boot Execution (PXE) and Dynamic Host Configuration Protocol. In addition to enabling system designers to eliminate redundant storage devices, remote booting enables fast updates to a client's operating system and application software, Curtiss-Wright said.
