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...
  • Trusted Services. A framework for developing and deploying device root-of-trust services across a range of secure processing environments such as those provided by OP-TEE and Hafnium. Continue on to the Trusted Services wiki...

These are the ones who are free birds and social butterflies. They love to go out of town and party unlimited. Unlike the wild ones at the Call Girl Powai these are the ones who will actually show you how's a party is done or how to party hard. These girls are the life of a party and will show you how to party.
