The Arm Confidential Compute Architecture (CCA) is an extension of the Armv9 architecture designed to provide confidential computing in standardised and scalable way. CCA builds on existing principles built for TrustZone and virtualization to create a scalable and secure solution. CCA places requirements on hardware and firmware, which together provide the trusted computing base for a new class of secure execution environment that we call a Realm. Trusted Firmware is the key community project that provides a reference implementation of open source Secure firmware for Arm-based processors. This talk briefly introduce Arm CCA and illustrate how Arm plans to develop and enable it in the open by leveraging the community effort that drives Trusted Firmware as open-source project.

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. TrustedFirmware.org 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.
