Trusted Execution Environment (TEE) is a standardized technology developed and promoted by GlobalPlatform . TEE is a separate execution environment that runs alongside the Rich OS and provides security services to that rich environment. The TEE isolates access to its hardware and software security resources from the Rich OS and its applications. The Figure below shows the architecture of the TEE.
Key concepts
At the highest level, a Trusted Execution Environment (TEE) is an environment where the following are true:
- Any code executing inside the TEE is trusted in authenticity and integrity.
- The other assets are also protected in confidentiality.
- The TEE shall resist to all known remote and software attacks, and a set of external hardware attacks.
- Both assets and code are protected from unauthorized tracing and control through debug and test features
