Green Hills Software Announces INTEGRITY PC™ Support for Intel® vPro™ Processor Technology

Improved Hardware Root of Trust for Secure Operating System

SANTA BARBARA , CA —August 27, 2007—Green Hills Software, Inc., the technology leader in device software optimization (DSO) and real-time operating systems (RTOS), today announced that Green Hills Software has extended its INTEGRITY PC™ secure operating system technology to take advantage of new security features in desktop PCs powered by the latest Intel vPro processor technology.

Trusted Execution
Green Hills Software’s INTEGRITY is the first and only operating system to undergo a high assurance Common Criteria security evaluation ( However, the operating system depends on the underlying hardware in order to realize its security policies. Intel vPro processor technology substantially enhances and simplifies the hardware root of trust required to establish a secure state for the platform. INTEGRITY PC works with Intel vPro processor technology to perform a secure boot in which the PC hardware, BIOS, and INTEGRITY kernel are measured to provide trust in the execution environment.

“We are excited about the silicon security innovations packed into Intel’s vPro,” commented David Kleidermacher, chief technology officer, Green Hills Software. “Intel has solved foundational trust problems that have prevented secure operating systems from completing their mission on off-the-shelf PCs. With INTEGRITY PC and Intel vPro processor technology, the PC platform can sustain applications and information requiring the highest levels of protection without sacrificing performance.”

INTEGRITY PC™ Technology
Green Hills Software’s INTEGRITY PC is a software platform designed for the military, intelligence, financial, medical, and other critical infrastructure communities where PC users must manage and protect high value information. INTEGRITY PC is based on the safety and security-certified INTEGRITY real-time operating system and incorporates a suite of secure software components, including Green Hills Software’s award-winning Padded Cell™ virtualization software. Padded Cell, optimized with Intel Virtualization Technology, enables multiple guest operating systems – such as Windows, Linux, and Solaris – and their applications to be run in secure partitions on the same computer. The resulting platform enables systems designers to build the most security-critical applications and run them alongside familiar operating environments, saving cost, size, weight, and power over multiple hardware platforms.

Multi-level Security
Military and intelligence communities struggle with the burden of maintaining separate computers and networks to manage information at varying sensitivity levels. INTEGRITY PC enables the consolidation of computers and networks, yielding enormous savings in size, weight, power, and cost. INTEGRITY PC manages information at multiple security levels, includes a cross-domain information transfer framework, provides a trusted path for the shared keyboard and mouse devices, and includes a multi-factor authentication mechanism.

About Intel vPro Technology
Intel vPro processor technology, powered by the revolutionary Intel Core™2 Duo processor, adds a new level of security and reliability to desktop PCs. Intel vPro processor technology’s security and management features include Intel Virtualization Technology (VT), Intel Trusted Execution Technology (TXT), and Intel Active Management Technology (AMT).

“Green Hills INTEGRITY PC software and Intel’s security and virtualization technologies work together to provide compelling new platform security and management capabilities,” said Gregory Bryant, vice president, Digital Enterprise Group and general manager, Digital Office Platform Division, Intel.

INTEGRITY PC runs on commercial, off-the-shelf (COTS) PC-compatible platforms. For specific availability information, contact
