Trusted Firmware is an open source project implementing foundational software components for creating secure devices. It currently consists of:
- Trusted Firmware-A. A reference implementation of secure world software for Arm A-Profile systems (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It leverages Arm TrustZone technology; this is different for A and M profile systems, which is why the project has two separate codebases. Continue on to the TF-A wiki...
- Trusted Firmware M. A reference implementation of secure world software for Arm M-Profile systems (Armv8-M). Continue on to the TF-M wiki...
- OP-TEE. A Trusted Execution Environment (TEE) designed as a companion to a non-secure Linux kernel running on Arm A-Profile systems (Armv8-A and Armv7-A) using TrustZone technology. On Armv8-A systems it runs at Secure-EL1. Continue on the the OP-TEE documentation...
- Hafnium. A reference Secure Partition Manager (SPM) for systems that implement the Armv8.4-A Secure-EL2 extension. It enables multiple, isolated Secure Partitions (SPs) to run at Secure-EL1.
- Mbed TLS. A C library implementing cryptographic primitives, X.509 certificate manipulation and the SSL/TLS and DTLS protocols. Its small code footprint makes it suitable for embedded systems. It has many users, including TF-A, TF-M and OP-TEE. Continue on to the Mbed TLS wiki...
