Trustonic: a way for mobile apps to benefit from ARM’s hardware-level security

This here narrative begins back in April, when ARM, Giesecke & Devrient and Gemalto teamed up and gave themselves precisely nine months in which to find the perfect brand name for their newly merged mobile security platform. Today, we're looking at the fruits of their efforts: Trustonic; a word which snappily captures the essence of what's at stake (trust-onic) and which you may soon encounter in connection with your next-gen smartphone, Mastercard payment app or 20th Century Fox DRM'd media.

What does Trustonic do, exactly? Pretty much what Mobicore already does in the Galaxy S III, or what Trusted Foundation does inside a Tegra-powered tablet: it allows certain pieces of software to tap into hardware-level encryption and authentication, courtesy of the TrustZone silicon that many ARM chips already contain, thereby removing many of the risks associated with malware and other intrusions within the mobile OS. As far as we understand it, the key difference with Trustonic is that it won't require direct input from OEMs like Samsung and NVIDIA, but will instead be more readily accessible to any banking, payment or DRM service that is willing to pay for a key. In return, the service would get enhanced security and faster logins for its users, who'd only need to enter a short, locally-verified PIN rather than wading through cloud-based steps to prove their identity. Indeed, perhaps that's where the tonic comes into it.

An ARM core in an AMD device? It just happened, but not the way you think

An ARM core in an AMD device? It just happened, but not the way you think

Yes, you heard right. AMD just added to ARM's burgeoning heap of gold coins, having licensed the British company's Cortex-A5 design for use in its own hardware. While this might sound like a dramatic capitulation on the part of the struggling giant, particularly after yesterday's news, it probably isn't. AMD says it'll use the ARM component solely for adding better security features to its next generation of business-focused laptops and tablets. A spokesperson told us the company's "commitment to x86 hasn't changed," referring to the fact that it'll continue to use its regular in-house chip architecture for the primary task of running applications.

The Cortex-A5 will be one tiny core squeezed in amongst everything else on the future 28nm silicon. It'll be dedicated to running ARM's proprietary TrustZone technology, which protects sensitive apps from tampering -- stuff like mobile payments, DRM, and nudge, nudge corporate documents. Rather than invent its own system for doing the same thing, AMD reckoned it'd be easier to work with ARM's, and who can blame it? If we remember rightly, even Intel made a similar call five years ago.
