Introduction

Building on the Beta version of the Trusted Services release, v1.0.0 is the first stable release of the project. The release comprises PSA Services that can be deployed on Cortex-A devices to meet PSA Certified requirements and, necessary build and test infrastructure and documentation.

The project provides a framework for developing and deploying device root-of-trust services for A- profile devices. The services in the project exists as Firmware Framework-A Secure Partitions. The Secure Partitions are managed by a Secure Partition Manager (SPM) running as part of a Trusted Operating System (e.g. OP-TEE) or Secure-EL2 Hypervisor (e.g. Hafnium) within a Trusted Execution Environment.

The deltas from the Beta release include:

More details around the latest changes, known issues etc. can be found in the Release Notes here.

OP-TEE 3.17 and beyond, supports SPMC. Further details can be found here. The diagram below shows a reference design for Trusted Services deployment.

About TrustedFirmware.org

TrustedFirmware.org is an open source project implementing foundational software components for creating secure devices.

Trusted Firmware provides a reference implementation of secure software for processors implementing both the A-Profile and M-Profile Arm architecture. It provides SoC developers and OEMs with a reference trusted code base complying with the relevant Arm specifications. Trusted Firmware code is the preferred implementation of Arm specifications, allowing quick and easy porting to modern chips and platforms. This forms the foundations of a Trusted Execution Environment (TEE) on application processors, or the Secure Processing Environment (SPE) of microcontrollers.
