Trusted Services v1.0.0-beta and enabling PSA Certified on Cortex-A devices

The Trusted Services project has made the first tagged release v1.0.0-beta. The release includes PSA Certified Secure Services that can be deployed on Cortex-A devices to meet PSA Certified requirements. The release also includes necessary build and test infrastructure and documentation content.

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 Core (SPMC) 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 release includes PSA Crypto, Storage and Attestation Secure Partitions exposing the PSA Certified Functional APIs, the same APIs available today on Arm v8-M Cortex-M platforms via Trusted Firmware- M. Additionally, UEFI SMM services are available through the SMM gateway Secure Partition. The services within the Secure Partitions can be invoked by applications for secure operations.

OP-TEE in 3.17 and later releases support Secure Partition Manager Core (SPMC). Details can be found here. The diagram below shows Trusted Services deployment on a reference platform.
