  • Device, system, and method of policy enforcement for rich execution environment
    Patent number: 11436343
    Abstract: Device, system, and method of policy enforcement for rich execution environment. An electronic device includes a Trusted Execution Environment (TEE), a Rich Execution Environment (REE), and a hardware-based secure sub-system which includes a cryptographic engine. The REE includes a cryptographic driver configured to initiate a request for TEE authorization to perform a particular cryptographic operation by the cryptographic engine on a data-item that is stored in a memory region that is accessible by the REE. The TEE includes a policies manager to determine whether the request from the REE is approved or rejected, and if approved, to inject data-items into the secure sub-system to enable performance of the requested cryptographic operation by the cryptographic engine.
