Trusted Execution Environment (TEE)
Security
Isolated execution region providing confidentiality and integrity guarantees for code and data.
Definition
A trusted execution environment isolates code and data from the main OS using hardware features. It can protect cryptographic operations and sensitive computations, but still needs careful design and updates.
In plain English
Isolated execution region providing confidentiality and integrity guarantees for code and data.
Why this matters
Why it matters: TEEs can reduce exposure of secrets and enable stronger security properties, but vulnerabilities can still exist.
Example
Example: Use TEE-backed key operations for authentication and ensure firmware updates and attestation where appropriate.
