Hardware security protects systems by building trust and isolation into physical components, using features such as secure enclaves, key storage and tamper resistance to defend against attacks software alone cannot stop.
Semantic Classification
Content
- Hardware security mechanisms include trusted execution environments, hardware security modules, secure boot and physical tamper resistance, providing isolated computation and protected key handling. They establish roots of trust that higher layers depend on.
- These features matter for protecting cryptographic keys, attesting device integrity and isolating sensitive data, including in XR devices that capture biometric information. They connect trusted execution environments to broader cryptography.
