Abbreviation for Trusted Execution Environment; hardware-assisted isolation for sensitive computation.

Definition

TEE refers to a trusted execution environment: hardware-assisted isolation that protects code and data from the normal operating system. It is used for key management, secure UI, and protected computations.

In plain English Abbreviation for Trusted Execution Environment; hardware-assisted isolation for sensitive computation.

Why this matters

Why it matters: It supports stronger security guarantees for privacy-sensitive operations, but still requires patching and threat modeling.

Example

Example: Use TEE-based attestation to prove code integrity before allowing access to sensitive keys.
