What is a Trusted Execution Environment (TEE)? Past, Present & Future

The Trusted Execution Environment (TEE) is a secure area in a device that ensures sensitive data is stored, processed, and protected in an isolated and trusted environment. As such, it offers protection against attacks generated in the rest of the device and even other actors inside the TEE.
