Green Hills Software, Inc’s INTEGRITY Secure Virtualization is now avaliable 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.

INTEGRITY Secure Virtualization technology can reduce development costs through processor consolidation, improve system security and reliability, and for mission critical applications it can reduce the certification burden for applications including 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.

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 compartmentalizes the secure zone into “metazones.” This reduces time to certification for specialized applications, such as key management and other financial transaction components. These applications share the secure zone with other critical components.

INTEGRITY Secure Virtualization offers several approaches to virtualization in ARM based 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.

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 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.
