The trusted Execution environment (TEE) is a secure area in CPU. It runs in a separate environment and in parallel with the operating system. The CPU ensures that the confidentiality and integrity of the code and data in the TEE are protected. TEE is more secure than an operating system by using both hardware and software to protect data and code. Trusted applications running in TEE have access to the full functionality of the device’s main processor and memory, and hardware isolation protects these components from user-installed applications running in the main operating system.
