TF-M: 2.0.0: Smaller footprint Trusted Firmware-M

Introduction

Trusted Firmware-M (TF-M) v2.0.0 was released on 28th November 2023. There is significant reduction in memory requirement compared to previous release (v1.8.0) due to the introduction of a small footprint ECC implementation in PSA Crypto service. The release includes build system changes splitting the secure TF-M and non-secure builds simplifying how non-secure builds integrate TF-M. Below are some of the highlights of the release.

Release Highlights

The project continuously tracks key KPIs in various modes using squad dashboard. In addition to the memory usage, the cycle counts of PSA FF-M API calls across the Trustzone boundary in SFN and IPC modes under the three PSA isolation levels are also included.

More details can be found here. Testing of the release has been done on Trustedfirmware.org Open CI. The next release will be in April 2024 which is tentatively planned to be TF-M’s first Long Term Stable (LTS) release. Any security fixes prior to the next release will be made available as patch releases in v2.0.x release branch.

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.

TrustedFirmware.org is member driven and member funded.
