Secure Enclave provides dedicated protection for supported key operations. It does not automatically protect all application code, copies of data or business permissions.
Evaluation approach
Supported key and authentication operations can benefit from hardware-backed security. Which data the application asks to sign, and for what purpose, remain design questions.
Application example
Even with a protected transaction key, separately verify that the recipient shown to the user matches the recipient in the signed data.
Limits and considerations
Strong key storage does not automatically prevent unauthorized key use in every context.
Hardware isolation and transaction intent
Secure Enclave is a dedicated platform component for supported security operations. Do not assume that all application data or every cryptographic algorithm executes there. Verify the API and key type in use.
Hardware protection can defend key material, but the data submitted for signing still matters. Bind displayed content to the approved operation and enforce scope on the server. Include device replacement and key loss in the lifecycle plan.
Checks and decisions
- Restrict key use
- Bind transaction content
- Design recovery
Assess raw-key extraction and unauthorized key use separately.
