- A collaborative effort into Firmware security and the path towards standardized open source Firmware on Arm


In a world of a trillion connected devices, Firmware security must be seen as a shared responsibility among all vendors and across different market segments, from Cloud to IoT. provides a collaborative platform to develop open source reference implementations of Secure world Software & Firmware on the Arm architecture, for both resource-constrained Microcontrollers and powerful Application processors. Moreover, as the architecture progresses and new security features and bespoke platform differentiator factors are deployed, there is an increasingly compelling need for simplification and consolidation of an open-source secure Firmware implementation. Trusted Firmware aims to fulfill that need, by constituting the standard secure basis of all connected devices, encouraging vendors to move their platform specific services into secure sandboxes, and by providing the foundation of the Arm Platform Security Architecture (PSA) Framework.
