Over the last month we have seen several key mobile device launches which shows the importance of mobile security to the Chinese market, and indicates a trend going global.

Fingerprint recognition has been possible for many years but ensuring its secure storage and use has been a more recent addition to mobile devices. We have seen fingerprint sensors first appearing in flagship mobile devices such as the Samsung Galaxy S6 – but last week Xiaomi launched a new phone, including a fingerprint sensor, at a $150 price point. This has been made possible by Xiaomi’s use of Trustonic’s Trusted Execution Environment (TEE) which builds on top of the already existent TrustZone technology that is built into every ARM Cortex-A class processor found in over 90% of mobile devices. This means this functionality can be included without additional chips needing to be designed in. Since it is hardware based it also is the quickest way of processing secure data giving a better user experience.

But it’s not just Xiaomi who is including the increased security that using the Trusted User Interface functionality of the Trustonic TEE enables. Over the last year Meizu also announced their MX5, Pro 5 and m1 metal that introduces their mTouch 2.0 security and fingerprint recognition which also benefits from the added security of using Trustonic TEE (http://www.meizu.com/en/products/mx5/mtouch.html)

With two leading Chinese mobile device manufacturers making security one of the central features of their new handsets, we expect to see more and more device manufacturers taking a similar approach. It shows the consumer demand to have more secure interactions via their mobile devices and they want this available across a wider range of mobile phones.

The Benefits of Trusted User Interface (TUI)

Trusted User Interfaces (TUIs) are the next big thing for securing critical mobile apps. The Trusted User Interface feature allows a Trusted Application to interact directly with the user via a common display and touch screen, completely isolated from the main device OS.

What is a Trusted Execution Environment (TEE)?

A Trusted Execution Environment (TEE) is an environment for executing code, in which those executing the code can have high levels of trust in that surrounding environment, because it can ignore threats from the rest of the device.

What is TrustZone?

Arm® TrustZone® technology provides a cost-effective methodology to isolate security critical components in a system, by hardware separating a rich operating system, from a much smaller, secure operating system.
