TEE System Architecture v1.1 | GPD_SPE_009 Jan 2017

This document explains the hardware and software architectures behind the TEE. It introduces TEE management and explains concepts relevant to TEE functional availability in a device.

This version of the TEE System Architecture has been extended to include the second phase of TEE standardization which introduced new API's for supporting tasks such as Trusted User interface, SE and Sockets communications, and remote management for Trusted Applications. Further extensions of the TEE System Architecture are expected in subsequent phases, as described in the TEE White Paper; e.g. a more flexible Trusted User Interface API, biometrics fingerprint API, secure video content.
