- * IDiceDevice specifies an interface that allows access to the Android instance's DICE artifacts.
- *
- * <h2>Features</h2>
- *
- * The dice device provides access to the component's CDI_SEAL and CDI_ATTEST secrets as well
- * as to its attestation certificate chain. The "component" is the Android instance running this
- * HAL service and the secrets and attestation chain must include all boot stage components,
- * the kernel, and the verified boot information (VBA).
- *
- * Implementations provide the following operations:
- * <li> sign - Signing a payload with a key derived from CDI_ATTEST.
- * <li> getAttestationChain - Retrieve the component's attestation certificate chain.
- * <li> derive - Retrieve the component's DICE artifacts.
- *
