Graphing_Graphene Confidential Compute Architecture (CCA), was introduced as an optional feature in Armv9.2 and is designed to provide protection for data in use, even from privileged software like the operating system or hypervisor. It builds on the security foundations of TrustZone and introduces hardware mechanisms like the Realm Management Extension (RME) to protect data and code even while they are in use. Is CCA utilized on Pixel 9 series? If not, are there plans to implement it on GrapheneOS?
DeletedUser405 Now that GrapheneOS is considering an alternative OEM with a Snapdragon SoC, would it be easier to implement this feature? How useful would CCA be for a smartphone?
