ViaSat Awarded Contract to Develop HAIPE IS Version 3 For Network Encryption Products

       Development Will Also Help Enable DoD Transition to IP Version 6

CARLSBAD, Calif., July 11 /PRNewswire-FirstCall/ -- ViaSat Inc. (Nasdaq: VSAT) has been awarded a contract for approximately $10 million from the Maryland Procurement Office (MPO) to implement Version 3 of the High Assurance Internet Protocol Encryptor Interoperability Specification (HAIPE IS) on ViaSat AltaSec® inline network encryptors. The multi-year contract covers development of software features for traffic protection, networking, and management designed to enable military communicators to establish highly secure encrypted links that will be accessible by future HAIPE devices. This compatibility of future HAIPE devices is especially important as the Department of Defense (DoD) transitions to Internet Protocol version 6 (IP v6).

In parallel to the funded development, ViaSat is conducting internally funded R&D projects to develop the next generation of inline encryption hardware. The internal development is centered on smaller, more durable, lower-cost versions of AltaSec products, as well as the next generation of ViaSat's PSIAM. PSIAM is a high-assurance crypto system designed to specifically address network-centric architectures and Cryptographic Modernization initiatives.

PSIAM is at the core of all ViaSat information assurance products, including its development of the Multifunctional Information Distribution System (MIDS) for the Joint Tactical Radio System (JTRS). PSIAM also powers the successful line of HAIPE IS compliant ViaSat AltaSec encryptors; the KG-250, KG-250A, and KG-255.

"We recognized that the real challenge is to design information assurance into network architectures from the beginning. The market acceptance of both our embedded and stand-alone encryptors in a variety of mobile and fixed applications shows that PSIAM fulfills that promise," said Jerry Goodwin, VP Tactical Networking and Information Assurance at ViaSat. "With the HAIPE v3 contract, supplemented by our ongoing investments in PSIAM technology, and smaller, more durable devices, we'll continue to provide affordable, high-strength information assurance to the network-centric battlefield."
