ARM TrustZone technology removes the need for separate secure hardware to authenticate the integrity of a device or an user. It does this by providing a true hardware root of trust in the main mobile chipset.

To ensure the integrity of the application, TrustZone also provides a secure execution environment where only trusted applications can operate, safe from hacker/virus/malware style attacks, a Trusted Execution Environment (TEE).

TrustZone hardware provides the isolation for the TEE from software attack vectors. The hardware isolation extends to securing data input and output all the way to the physical peripheral, including for example, the keypad/touchscreen.

Armed with these key capabilities, chipsets equipped with TrustZone technology provide a wealth of opportunities to redefine the services users can access (more, better), how they access them (faster, easier), and where they can access them (anywhere, anytime).
