Secure Enclave provides a strong boundary for supported key operations. It does not automatically contain every application secret or key type.
Evaluation approach
Choose supported keys, use conditions and access controls. Assess unauthorized key use even when export is impossible.
Application example
Bind signed content to the server transaction. Hardware storage does not prevent signing an incorrect amount.
Limits and considerations
Hardware protection does not replace application logic or account authorization.
What remains if extraction is prevented?
Extracting a raw key differs from inducing the application to perform an unwanted operation with it. Verify transaction content, user approval and server challenges together to address the latter risk.
Checks and decisions
- Verify key types
- Bind signed data
- Test access conditions
