Certifying COTS avionics hardware to DAL A is common sense - Story
September 29, 2016
Modern avionics systems continue to become more complex for not only military aircraft, but also commercial aircraft adapting the latest digital cockpits. This complexity and demand for increased performance has placed more pressure on industry and the civil safety certification authorities for aviation worldwide to develop processes for certifying commercial-off-the-shelf (COTS) hardware to highest safety certification level ? Design Assurance Level (DAL) A. In this Q&A with Paul Hart, Chief Technology Officer (CTO) for Curtiss-Wright Defense Solutions, he discusses the objections from the civil aviation authorities to this concept as well as the benefits that occur from certifying COTS hardware to DO-254 DAL A, its similarities to certifying software to DO-178C, and how it might apply to unmanned aircraft. Edited excerpts follow.

NSA-approved two-layer encryption approach slashes cost and development time - Story
September 16, 2016
In today's world, it is becoming increasingly important to be able to protect classified data-at-rest with encryption for critical data, such as that captured and stored during airborne intelligence, surveillance, and reconnaissance (ISR) missions. For some programs with limited budgets and schedule, using National Security Agency (NSA)-approved Type 1 encryption, the highest level of data protection, may prove impractical due to the high cost - typically several millions of dollars for a new development - and long process - typically two to three years that it takes to reach full certification. The cost and schedule required to deliver Type 1 encrypted hardware has meant that industry's ability to provide robust data protection has lagged far behind the demand.

Developing effective hardware and software COTS security technologies - Story
August 17, 2016
The armed forces of the United States and its allies around the world rely on critical military technology that is under constant threat. These threats range from the reverse-engineering of systems lost on the battlefield to the accidental introduction of counterfeit components on the factory floor. In response, commercial off-the-shelf (COTS) suppliers are more frequently being called upon to help users address rapidly expanding requirements for anti-tamper (AT) and cybersecurity or information assurance (IA) capabilities.

High-speed ADC/DAC and FPGAs drive the design of next-generation SATCOM systems - Story
July 28, 2016
Many military satellite communications (SATCOM) systems operate in the very-high-frequency S-band (2 to 4 GHz) and C-band (4 to 8 GHz) range. Accurate sampling of satellite communications requires frequency rates that are at least twice, but preferably 2.5 to 3 times, the speed of the carrier frequency.

Turbocharge HPEC system design with HPC development tools - Story
July 25, 2016
As parallel programming grows in importance and popularity, the critical challenge has become how to intelligently manage, develop, and debug the increasingly complex code. Traditional tools such as trace analysis, serial debuggers, and the venerable "printf"statement just aren't up to the task. Although some commercial off-the-shelf (COTS) vendors and customers in the embedded-defense space have attempted to develop their own parallel programming tools, the task has proved difficult and the resulting tools are far from full-featured. What's more, using proprietary development tools can add risk to a program's cost and schedule. The good news: A better source of tools for designing cutting-edge high-performance embedded computing (HPEC) systems already exists in an adjacent market - the commercial high-performance computing (HPC) market. Sourcing proven and powerful tools from the HPC community, long supported by an expansive user base, can greatly speed delivery time while decreasing costs and program risk.
