HERNDON, VA - October 27, 2005 - Objective Interface Systems, Inc., the leading provider of high-performance, safe and secure communications middleware for mission-critical systems, today announced its co-sponsorship of the 24th annual Digital Avionics Systems Conference (DASC). With a presentation of new technologies for high-assurance safety and security in avionics systems, Objective Interface will speak directly to the theme of this year’s DASC: Avionics in a Changing Marketplace: Safe and Secure? Objective Interface will discuss how MILS (Multiple Independent Levels of Security), a foundational software architecture co-designed by Objective Interface Systems, Lockheed Martin, Rockwell Collins, Boeing, the United States Air Force Research Laboratory (US AFRL), the National Security Agency (NSA) and others has been created to meet the gravest security threats to mission-critical systems, such as attacks on avionics communications systems. Objective Interface will also present on how the Partitioning Communications System (PCS), the foundation for MILS communications middleware, enables high assurance, security and safety for communication among avionics systems. Through the availability of a new crop of commercially available MILS-compliant software products and development tools from companies such as Objective Interface, Green Hills Software, LynuxWorks and Wind River, designers can now substantially better protect against threats to their embedded and real-time avionics systems.

“Having long worked with the leaders in embedded and real-time avionics systems, we understand their need for a software architecture specifically developed for the highest levels of security: DO-178B Level A and EAL 6+,” said Joe Jacob, Senior Vice President, Objective Interface Systems. “MILS-compliant software was born directly of that need. It allows avionics designers a smoother upgrade path from existing to high-assurance security systems. As a co-sponsor of DASC, we have the opportunity to further explore the security requirements of avionics systems designers. We are committed to supporting them as they create the next-generation systems in communications infrastructure (NEXCOM), navigation (WAAS and LAAS), air traffic management and global air traffic management (GATM), and launch technology.”

Objective Interface at DASC
As a co-sponsor of the event, Objective Interface will participate in the conference and exhibition at DASC. Mentoring Engineer Gordon Uchenick will present a tutorial on MILS on Sunday, October 30, 2005 from 11:30 a.m.-2:30 p.m. Bill Beckwith, CEO/CTO, will present a paper on the Partitioning Communications System on Thursday, November 3, 2005 from 8:30-9:00 a.m. The company will also host a booth in the exhibition area of DASC, from Monday, October 31-Wednesday, November 2. Designers who would like more information on MILS and on PCSexpress, the distributed communications systems for MILS that was invented by Objective Interface, are encouraged to stop by the Objective Interface booth.

About DASC
The 24th annual DASC will take place October 30-November 5, 2005 at the Hyatt Regency Crystal City, Washington, DC. This year’s conference is focused on the ways in which the worlds of aeronautics and aerospace are involved in a transition from the design and implementation of the next generation to the design and implementation of safe and secure next-generation avionics.
