Trusted Execution Environment (TEE), Implementations, Drawbacks

The Trusted Execution Environments are one of the technologies that help manufacturers, service providers, and consumers protect their devices and sensitive data. TEE protects the area of the hardware where the code is executed in isolation. The code executed in the trusted execution environment cannot be viewed or modified, so an attacker would only be able to execute malicious code with full privileges on the same processor.

A Trusted Execution Environment (TEE) is an environment in which the executed code and the data that is accessed are physically isolated and confidentially protected so that no one without integrity can access the data or change the code or its behavior. We are not aware of many devices in the US that use trusted execution environments, including smartphones, set-top boxes, video game consoles, and Smart TVs. A TEE is a secure and integrity-protected processing environment that consists of processing, and storage capabilities.
