ARM links with Trusted Logic for secure mobiles

ARM Ltd has teamed with Trusted Logic to develop secure software for mobile handsets and set-top boxes that will combine the microprocessor core maker's TrustZone technology with optimized security software from TrustZone.

The security software, when coupled with the TrustZone technology, will also protect against common hardware attacks and frauds such as mobile phone security codes being overwritten. Overwritten codes mean operators lose revenue, increasing the cost to mobile phone users.

As part of the deal, ARM will also be able to offer Trusted Logic's existing Security Module software, which is already compatible with ARM cores and provides a smooth upgrade to TrustZone enabled cores.

The software will be available in the first quarter of 2005, while Trusted Logic's security module will start sampling in the third quarter of 2004. Both are now available for licensing from ARM.

ARM stressed the new software will complement the TrustZone microprocessor technology, offering a common framework for less fragmented secure software development. The company said common security building blocks and a consistent framework across a number of platforms and applications reduce time-to-market for OEMs, as well their development and integration costs when embedding security into devices.

"The addition of this TrustZone technology-optimized software to our current microprocessor offerings means that we can offer OEMs a suite of flexible security options that protects device integrity and personal information "giving consumers and manufacturers peace of mind," Mary Inglis, ARM's director of OS & Alliances, said in a statement.

Dominique Bolignano, president and CEO, Trusted Logic, added, "By concentrating security functions into a single, specialized software component, our TrustZone technology-optimized solution will provide operators and handset vendors with portable, interoperable and certifiable security."

Last month, ARM reach agreement with Texas Instruments Inc. to combine the companies' Omap and TrustZone technologies to develop a silicon-based system for secure wireless transactions. TI said extending its collaboration with ARM was part of its strategy to address growing security concerns among mobile service providers, wireless original equipment manufacturers and mobile devices users.
