TrustZone technology for Armv8-A

Architecture of Trusted Execution Environment Information Slide.

Arm TrustZone is used on billions of applications' processors to protect high-value code and data. It is frequently used to provide a security boundary for a GlobalPlatform Trusted Execution Environment.

TrustZone is built on Secure and Non-secure worlds that are hardware separated. The partitioning of the two worlds is achieved by hardware logic present in the AMBA bus fabric, peripherals and processors.

In order to implement a Secure state in the SoC, trusted software (Trusted OS) needs to be developed to make use of the protected assets. This code typically implements trusted boot, the Secure world switch monitor, a small trusted OS and trusted apps. The combination of TrustZone based hardware isolation, trusted boot and a trusted OS make up a Trusted Execution Environment (TEE), which can be used alongside other security technology.
