LynuxWorks Unveils Next-Generation Separation Kernel and Embedded Hypervisor

LynxSecure 2.0 Enables Concurrent Execution of Different OS Environments on Today's Powerful Multicore Processors

NUREMBERG, GERMANY and SAN JOSE, CA--(Marketwire - February 26, 2008) - EMBEDDED WORLD 2008 EXHIBITION & CONFERENCE -- Previewing its latest innovation in secure embedded computing, LynuxWorks, Inc., a world leader in embedded software, today unveiled LynxSecure 2.0, its next-generation separation kernel and embedded hypervisor. Designed to take advantage of today's and tomorrow's advanced hardware architectures, LynxSecure 2.0 virtualizes the underlying hardware to enable multiple different operating systems (OS) to co-exist on the same platform. This ability to consolidate heterogeneous OS environments enhances the ability to offer a diverse array of applications on a single processor, which reduces hardware costs and allows for easier reuse of legacy software.

Embedded hypervisors allow for traditionally non real-time operating systems (RTOS) such as Linux or Windows to co-exist on the same hardware as a more traditional RTOS, such as LynuxWorks' flagship product, LynxOS. A separation kernel's primary function is to partition system resources among those "guest" operating systems, sequester data and control the flow of information among partitions. Because LynxSecure's separation kernel and hypervisor are small and efficient, they maintain hard real-time characteristics and determinism for real-time applications and give non real-time applications their own time slice of the processor. Paired, the two technologies provide a robust foundation for the creation of multi-level, secure systems.

For example, with aircraft becoming more connected to the world at large, it is possible that Internet availability will be a requirement in the cockpit. Until now, this would have required an additional computer system to ensure this capability was separate from the flight controls. By using an embedded hypervisor, the web browser could run in its own secure partition running on Windows or a Linux guest OS, with the hypervisor and separation kernel making sure that any possible threat or fault is contained, and will not affect the safety-critical cockpit systems.

"Hypervisors might be the hot topic in computing these days, but LynuxWorks is no newcomer to this technology," said Gurjot Singh, CEO, LynuxWorks. "With the introduction of LynxSecure 2.0, we are once again demonstrating that LynuxWorks is an industry leader in technology innovation. LynxSecure 2.0 enables the creation of multi-level systems with advanced security needs, such as those commonly found in the military and other high-security industries, such as medical, financial services and industrial control."

LynxSecure 2.0 builds upon its predecessor, and continues to offer the ability to run on any 32-bit or 64-bit MMU processor, provides 100 percent application binary compatibility between a standalone OS and its virtualized version. Like all LynuxWorks' products, LynxSecure is based on open standards but it also offers the highest real-time safety and security methods, conforming to the MILS standard and certifiable to DO-178B Level A.

Other key features in LynxSecure 2.0 include:

-- Multiprocessing, which enables developers to take advantage of the latest, multicore processor designs;

-- A lightweight application run-time environment for creating secure applications;

-- Device assignment capabilities that allow for specific devices to be assigned to their own partitions and ensure system security when

communicating with external devices; and

-- Security enhancements for policy definition and enforcement, including controlled communication among partitions

LynxSecure 2.0 will be available in summer 2008. For more information about LynxSecure and other LynuxWorks products please visit
