README.md

Host process substituting for a TEE (Trusted Execution Environment). Used to run backing implementations of Android HALs that normally delegate to a TEE environment, specifically ConfirmationUI, Gatekeeper, and Keymint.

Gatekeeper and Keymint communicate with secure_env through virtio-console channels connected to FIFO files on the host. The display part of ConfirmationUI is runs in the webRTC host process, which delegates signing operations only to secure_env.

Before entering the kernel, the u-boot bootloader writes some information about the device image files into the keymint channel to prepare it with the authenticated version number of the operating system.
