TrustZone Downgrade Attack Opens Android Devices To Old

PSA provides a common security foundation for the whole IoT ecosystem. It includes many elements, including architecture specifications and threat models. An important part of PSA is open source firmware. This is available in the form of Trusted Firmware-M for Arm Cortex-M23 and Arm Cortex-M33 processors, which use Arm TrustZone technology. Trusted Firmware - Open Source Secure World Software Arm Trusted Firmware provides a reference implementation of secure world software for Armv8-A and Armv8-M. It provides SoC developers and OEMs with a reference trusted code base complying with the relevant Arm specifications. Open Enclave SDK Open Enclave SDK is an open source SDK targeted at creating a single unified enclaving abstraction for developer to build Trusted Execution Environment (TEEs) based applications. As TEE technology matures and as different implementations arise, the Open Enclave SDK is committed to supporting an API set that allows developers to build once and

TEE Linux kernel support and open source security [Free

AOSP is open and free. Android is closed and not free. Further, Android being 100% secure won't fix this. This is an issue similar to Intel's fuck up with AMT. AMD uses ARM TrustZone bits in their processors as well. AMD calls it the PSP.
