Green Hills Software Announces Comprehensive Solution for ARM TrustZone Technology-Based Devices

SANTA CLARA, CA -- (MARKET WIRE) -- Oct 21, 2009 -- Techcon3 2009 -- Green Hills Software, Inc., the largest independent vendor of embedded software solutions, today announced INTEGRITY Secure Virtualization for ARM® TrustZone® technology. INTEGRITY® Secure Virtualization (ISV) is built on Green Hills Software's INTEGRITY RTOS, the first and only operating system technology to be certified by the NSA to EAL6+ High Robustness, the highest level of security ever achieved for any software product.

INTEGRITY Secure Virtualization reduces costs through processor consolidation, improves system security and reliability, and reduces the certification burden in mission critical applications such as banking, industrial control, and medical systems. ISV supports TrustZone technology-enabled ARM cores -- including the ARM1176JZ(F)-S™, Cortex™-A8 and Cortex-A9 processors -- on leading system-on-chip (SoC) implementations from Texas Instruments Incorporated (TI), Freescale, and other semiconductor partners.

"ARM's TrustZone technology provides a high-performance yet power-efficient approach to virtualization," said Gordon Jones, vice president of Green Hills Software's Embedded Virtualization Business Unit. "INTEGRITY Secure Virtualization enables the deployment of trustworthy applications, such as network authentication and digital rights management, sandboxed from the general purpose operating environment. This architecture enables ARM Powered® devices to enjoy the best of both worlds -- uncompromising security alongside all the bells and whistles of Linux, Android, Windows® Mobile, and other leading multimedia environments."

"We are pleased to welcome Green Hills Software to ARM's ecosystem of TrustZone software providers," commented Mike Inglis, executive vice president and general manager, ARM Processor Division. "ARM TrustZone technology coupled with software such as INTEGRITY Secure Virtualization delivers the security foundations for mobile and consumer devices that are increasingly called upon to manage critical information."

"Green Hills Software is a long-time leading software supplier for TI's OMAP35x customers who design a wide breadth of products ranging from medical devices to industrial automation," commented Alejandro Erives, OMAP35x marketing manager, TI. "The new hypervisor and management capability of INTEGRITY Secure Virtualization offers our customers the confidence that their designs are built on a proven, secure and reliable platform."

"Green Hills Software is a leading supplier of systems software solutions that are applicable for sophisticated devices in consumer and automotive infotainment systems," commented Ken Obuszewski, director of product management for Freescale's Multimedia Applications Group. "INTEGRITY Secure Virtualization provides an excellent match for the extensive security, management, and multimedia capabilities of the Freescale i.MX515 applications processor."

INTEGRITY Secure Virtualization for TrustZone Technology

INTEGRITY Secure Virtualization consists of the certified INTEGRITY operating system technology coupled with facilities to execute one or more "guest" operating systems on TrustZone technology-enabled SoCs. INTEGRITY Secure Virtualization also provides a communications interface for the normal zone to request services of the secure zone. This architecture enables security and reliability-critical applications to safely execute with guaranteed memory, CPU time resources, and device access control, regardless of what is happening in the normal zone.

INTEGRITY uses its proven resource management and protection capabilities and the ARM memory management unit (MMU) to compartmentalize the secure zone into "metazones." This further reduces time to certification for specialized applications, such as key management and other financial transaction components, which must share the secure zone with other critical components.

INTEGRITY Secure Virtualization offers several approaches to virtualization in ARM Powered devices. In addition to managing critical applications in the secure zone, INTEGRITY can run in the normal zone, using paravirtualization to host Linux and other guest operating systems. Alternatively, INTEGRITY Secure Virtualization can host unmodified guest operating systems ("full" virtualization) by taking advantage of TrustZone hardware features.

For device manufacturers who must support multiple multimedia operating systems, INTEGRITY Secure Virtualization can provide significant cost and time-to-market savings by enabling all of these operating systems to run on the latest hardware without porting.

Applications of ISV for TrustZone Enabled Devices

In addition to the compartmentalization and virtualization of guest operating systems, INTEGRITY Secure Virtualization and its EAL6+ certified security policies deliver solutions for many of the world's long unresolved security problems, including the ability to safely browse the Internet and use email; trust the launch and execution of special-purpose applications such as virus scanning software and system firmware updates; protect sensitive personal and medical records from compromise; and guarantee the authenticity and integrity of cash withdrawals, wire transfers, point-of-sale transactions, and other high value financial applications.

The Broadest Software Ecosystem

In addition to its security and reliability features, INTEGRITY Secure Virtualization comes with more than a decade of tools and middleware ecosystem to help device manufacturers develop and deploy products faster. INTEGRITY is supported by thousands of device drivers, network stacks, file systems, Java virtual machines, and many other components -- pre-integrated and ready to deploy.


INTEGRITY Secure Virtualization runs on commercial, off-the-shelf platforms such as the Texas Instruments OMAP 35x and Freescale i.MX515. For specific availability information, contact Email Contact.
