+/**
+ * An IRemotelyProvisionedComponent is a secure-side component for which certificates can be
+ * remotely provisioned. It provides an interface for generating asymmetric key pairs and then
+ * creating a CertificateRequest that contains the generated public keys, plus other information to
+ * authenticate the request origin. The CertificateRequest can be sent to a server, which can
+ * validate the request and create certificates.
+ *
+ * This interface does not provide any way to use the generated and certified key pairs. It's
+ * intended to be implemented by a HAL service that does other things with keys (e.g. KeyMint).
+ *
+ * The root of trust for secure provisioning is something called the Device Identifier Composition
+ * Engine (DICE) Chain. The DICE Chain is a chain of certificates, represented as COSE_Sign1 objects
+ * containing CBOR Web Tokens (CWT) which have descriptions about the stage of firmware being
+ * signed, including a COSE_Key representation of that stage's public key.
+ *
+ * DICE Chain Design
+ * =================
+ *
+ * For a more exhaustive and thorough look at DICE and the implementation used within this protocol,
+ * please see: https://pigweed.googlesource.com/open-dice/+/HEAD/docs/specification.md
+ *
+ * The DICE Chain is designed to mirror the boot stages of a device, and to prove the content and
+ * integrity of each firmware image. In a proper DICE Chain, each boot stage hashes its own private
+ * key material with the code and any relevant configuration parameters of the next stage to produce
+ * a Compound Device Identifier, or CDI, which is used as the secret key material for the next
+ * stage. From the CDI, a key pair - CDI_*_Pub and CDI_*_Priv - is derived and certified for the
+ * next stage by the current stages CDI_*_Priv. The next stage is then loaded and given its CDI and
+ * the DICE certificate chain generated so far in a manner that does not leak the previous stage's
+ * CDI_*_Priv or CDI to later boot stages. The final, "leaf" CDI certificate contains a public key,
+ * denoted CDI_Leaf_Pub, whose corresponding private key, denoted CDI_Leaf_Priv, is available for
+ * use by the IRemotelyProvisionedComponent.
+ *
+ * The root keypair is generated by immutable code (e.g. ROM), from a Unique Device Secret (UDS).
+ * The keypair that is generated from it can be referred to as the UDS_Pub/UDS_Priv keys. After the
+ * device-unique secret is used, it must be made unavailable to any later boot stage.
+ *
+ * In this way, booting the device incrementally builds a certificate chain that (a) identifies and
+ * validates the integrity of every stage and (b) contains a set of public keys that correspond to
+ * private keys, one known to each stage. Any stage can compute the secrets of all later stages
+ * (given the necessary input), but no stage can compute the secret of any preceding stage. Updating
+ * the firmware or configuration of any stage changes the key pair of that stage, and of all
+ * subsequent stages, and no attacker who compromised the previous version of the updated firmware
+ * can know or predict the post-update key pairs. It is recommended and expected that the DICE Chain
+ * is constructed using the Open Profile for DICE.
+ *
+ * When the provisioning server receives a message signed by CDI_Leaf_Priv and containing a DICE
+ * chain that chains from UDS_Pub to CDI_Leaf_Pub, it can be certain that (barring vulnerabilities
+ * in some boot stage), the CertificateRequest came from the device associated with UDS_Pub, running
+ * the specific software identified by the certificates in the chain. If the server has some
+ * mechanism for knowing the hash values of compromised stages, it can determine whether signing
+ * certificates is appropriate.
+ *
+ * Degenerate DICE Chains
+ * ======================
+ *
+ * While a proper DICE Chain, as described above, reflects the complete boot sequence from boot ROM
+ * to the secure area image of the IRemotelyProvisionedComponent, it's also possible to use a
+ * "degenerate" DICE Chain which consists only of a single, self-signed certificate containing the
+ * public key of a hardware-bound key pair. This is an appropriate solution for devices which
+ * haven't implemented everything necessary to produce a proper DICE Chain, but can derive a unique
+ * key pair in the secure area. In this degenerate case, UDS_Pub is the same as CDI_Leaf_Pub.
+ *
+ * DICE Chain Privacy
+ * ==================
+ *
+ * Because the DICE Chain constitutes an unspoofable, device-unique identifier, special care is
+ * taken to prevent its availability to entities who may wish to track devices. Three precautions
+ * are taken:
+ *
+ * 1) The DICE chain is only handled by the native Remote Key Provisioning Daemon (RKPD) service on
+ *    the HLOS and is not exposed to apps running on device.
+ *
+ * 2) The CDI_Leaf_Priv key cannot be used to sign arbitrary data.
+ *
+ * 3) Backend infrastructure does not correlate UDS_Pub with the certificates signed and sent back
+ *    to the device.
+ *
+ * Versioning
+ * ==========
+ * Versions 1 and 2 of the schema, as previously defined in DeviceInfo.aidl, diverge in
+ * functionality from Version 3. Version 3 removes the need to have testMode in function calls and
+ * deprecates the Endpoint Encryption Key (EEK) as well. Vendors implementing Version 1
+ * (Android S/12) or Version 2 (Android T/13) do not need to implement generateCertificateRequestV2.
+ * Vendors implementing Version 3 (Android U/14) need to implement generateCertificateRequestV2.
+ *
+ * For better coverage of changes from version to version, please see RKP_CHANGELOG.md in the root
+ * of the keymint interface directory.
