OpenCCA

An Open Framework to Enable Arm CCA Research

What is OpenCCA?

OpenCCA is an open research framework designed to enable early exploration and evaluation of Arm Confidential Compute Architecture (CCA) on vendor lock-free non-CCA hardware.

This makes it possible to estimate the performance of Arm CCA research designs and interact with real-world peripherals, going beyond the capabilities of pure software simulation.
