ARM Builds Security Foundation For Future Wireless And Consumer Devices

27 May 2003

TrustZone extension delivers hardware Security for next generation, open system, ARM Powered® solutions

CAMBRIDGE, UK – May 27, 2003 – ARM [(LSE:ARM);(Nasdaq:ARMHY)], the industry's leading provider of 16/32-bit embedded RISC microprocessor solutions, today announced TrustZone™ technology, a new security extension to the ARM® architecture. TrustZone technology provides a secure foundation for systems running open Operating Systems (OS), such as Linux, Palm OS®, Symbian OS and Windows CE. In addition, TrustZone technology complements secure application environments such as Sun Microsystems' Java™ technology by making security implementation on devices more efficient.

ARM is delivering its TrustZone technology in response to industry demands for greater levels of security in a range of digital electronic devices such as set-top boxes, next-generation smart phones and payment and network equipment. To date, manufacturers have had difficulty delivering on the promises of security and reliability in these devices where the download and execution of potentially harmful rogue data and applications can infect the device.

ARM TrustZone technology will ensure that data downloaded or run on the device remains secure, protecting consumer privacy and opening up a range of services, such as mobile banking and multimedia entertainment to wider consumer use. In turn, network operators and service providers will benefit from a consumer uptake of these innovative services.

"Phone software must remain inviolate from any actions of downloaded software, and only hardware-enforced security can provide this level of trust," said Martin Reynolds, Gartner fellow, Gartner. "Security-enhanced processors are an essential component for the future of mobile phone technology, opening the way for a vast ecosystem of third-party applications."

ARM TrustZone technology is implemented within the microprocessor core itself, enabling the protection of on- and off-chip memory. Since the security elements of the system are designed into the core hardware, security issues surrounding proprietary, non-portable solutions outside the core are removed. In this way, security is maintained as an intrinsic feature at the heart of every device, with minimal impact to the core area or performance, while enabling developers to build any additional security, for example cryptography, onto the secure hardware foundation.

"Concern over security in both wired and mobile applications is becoming a top priority for operators, service providers and consumers who require extremely high attention to be paid to data protection and integrity. Consumers now expect their data access devices to be secure, to enable them to use the growing number of public applications now available," said Richard York, Secure Technology Program manager, ARM. "Increasingly, designers are finding it problematic to address security only at the software level. ARM is addressing this issue with the TrustZone extensions, by integrating security into the very heart of our cores."

ARM TrustZone technology tags and partitions secure code and data within the system, and maintains a clear, hardware separation between secure and non-secure information. This separation enables secure code and data to run alongside an OS securely and efficiently, without being compromised or accessible to attack.

TrustZone technology will be available for licensing in ARM CPU cores in 2004. The TrustZone specification is available now. For more information contact ARM, or go to the ARM website at http://www.arm.com .

EDITORS' NOTE: Industry leaders are already endorsing ARM TrustZone technology:

"It is becoming increasingly more difficult to create a secure payment system, especially as payment terminals become progressively more complex and feature rich. As the leader in secure payment transactions, Ingenico evaluated the TrustZone architecture and we found it to provide significant value in creating a secure structured implementation."
John Sheets, vice president, security officer, Ingenico

"TrustZone technology introduces new security capabilities to the market that are highly complimentary to Insignia's Secure System Provisioning product. ARM's new technology will enable us to provide an even more secure environment for Over-The-Repair capabilities in TrustZone technology-enabled devices."
Peter Bernard, chief product officer, Insignia

"As the leading provider of Linux-based systems software platforms, we are excited by this new initiative from ARM. Thanks to the ubiquity of the ARM architecture, wireless device OEMs look to ARM for the latest technology. We are working closely with ARM to provide secure Linux-based solutions for the next wave of wireless devices."
Bill Weinberg, director, Strategic Marketing, MontaVista Software

"Managing system security and accelerating market delivery are becoming ever more important to the success of wireless devices like next-generation Palm Powered products. Palm OS licensees will be pleased with the steps ARM is making toward achieving both goals by introducing the TrustZone architecture."
Charlie Tritschler, VP of Product Marketing, PalmSource

"ARM is a strategic partner of SafeNet and we are working co-operatively to address wireless security needs in the industry. ARM's announcement today of TrustZone technology is a critical component of the security solution for wireless devices and a natural evolution of ARM devices that include peripheral security solutions today. We are looking forward to the continued evolution of the TrustZone initiative and providing our EmbeddedIP technology as part of the solution."
David Potts, senior vice president and GM, Embedded Security Division, SafeNet.

"Symbian and ARM have worked in close partnership for many years to develop Symbian OS exclusively on the ARM architecture and to establish Symbian OS as the industry standard operating system for advanced mobile phones. Symbian firmly believes that ARM's TrustZone technology will be adopted widely and will become a standard underlying platform for the provision of security services, helping to accelerate manufacturers' time-to-market for handsets with enhanced security solutions."
Jonathan Harris, strategic product manager, Hardware Integration, Symbian Ltd
