+// Note: When transitioning to loading of XML configs, either keep the configuration

+//   1. The "Remote Submix In" device is listed in the XML config as "attached",
+//      however in the AIDL scheme its device type has a "virtual" connection.
+//   2. The canonical r_submix configuration only lists 'STEREO' and '48000',
+//      however the framework attempts to open streams for other sample rates
+//      as well. The legacy r_submix implementation allowed that, but libaudiohal@aidl
+//      will not find a mix port to use. Because of that, list all sample rates that
+//      the legacy implementation allowed (note that mono was not allowed, the framework
+//      is expected to upmix mono tracks into stereo if needed).
+//   3. The legacy implementation had a hard limit on the number of routes (10),
+//      and this is checked indirectly by AudioPlaybackCaptureTest#testPlaybackCaptureDoS
+//      CTS test. Instead of hardcoding the number of routes, we can use
+//      "maxOpen/ActiveStreamCount" to enforce a similar limit. However, the canonical

 /**
- * Interface representing a remote wakeup client.
+ * The remote access HAL.
  *
- * A wakeup client is a binary outside Android framework that communicates with
- * a wakeup server and receives wake up command.
+ * <p>This HAL represents an external system that is always on even when Android
+ * is powered off. It is capable of wakeing up and notifying Android when a
+ * remote task arrives.
+ *
+ * <p>For cloud-based remote access, a cloud server will issue the remote task
+ * to the external system, which will then be forwarded to Android. The client
+ * is expected to call {@code setRemoteTaskCallback} to register the remote
+ * task callback and uses the information returned from {@code getVehicleId},
+ * {@code getWakeupServiceName} and {@code getProcessorId} to register with
+ * a remote server.
+ *
+ * <p>For serverless remote access, the remote task comes from the external
+ * system alone and no server is involved. The external system may support
+ * scheduling a remote task to executed later through {@code scheduleTask}.
+ *
+ * <p>For both cloud-based and serverless remote access, the ideal use case
+ * is to wake up Android when the vehicle is not in use and then shutdown
+ * Android after the task is complete. However, user may access the vehicle
+ * during this period, and Android must not be shutdown if this happens.
+ *
+ * <p>If this interface is implemented, then VHAL property
+ * {@code VEHICLE_IN_USE} must be supported to represent whether the vehicle is
+ * currently in use. Android will check this before sending the shutdown
+ * request.
+ *
+ * <p>The external power controller system must also check whether vehicle is
+ * in use upon receiving the shutdown request and makes sure that an
+ * user-unexpected shutdown must not happen.

-# Virtual Face HAL

-on debuggable builds to allow devices to masquerade as alternative device
-types and for emulators.
+This is a virtual HAL implementation that is backed by system properties instead
+of actual hardware. It's intended for testing and UI development on debuggable
+builds to allow devices to masquerade as alternative device types and for
+emulators. Note: The virtual face HAL feature development will be done in
+phases. Refer to this doc often for the latest supported features
 
-## Device Selection
+## Supported Devices
 
-You can either run the FakeFaceEngine on a [real device](#actual-device) or a [virtual device/cuttlefish](#getting-started-on-a-virtual-device-cuttlefish). This document should
-help you to get started on either one.
+The face virtual hal is automatically built in in all debug builds (userdebug<br/>
+and eng) for the latest pixel devices and CF. The instructions in this doc<br/>
+applies to all
 
-After setting up a device, go ahead and try out [enrolling](#enrolling) & [authenticating](#authenticating)
+## Enabling Face Virtual HAL
 
-### Getting started on a Virtual Device (cuttlefish)
+On pixel devicse (non-CF), by default (after manufacture reset), Face VHAL is <br/>
+not enabled. Therefore real Face HAL is used. Face VHAL enabling is gated by the<br/>
+following two AND conditions:<br/>
+1. The Face VHAL feature flag (as part ofTrunk-development strategy) must be<br/>
+   turned on until the flags life-cycle ends.
+2. The Face VHAL must be enabled via sysprop.
 
+See the adb commands below
 
-Note, I'm running this via a cloudtop virtual device.
+## Getting Stared
 
-1. Setup cuttlefish on cloudtop, See [this](https://g3doc.corp.google.com/company/teams/android/teampages/acloud/getting_started.md?cl=head) for more details.
-2. acloud create --local-image
-3. Enter in the shell command to disable hidl
+A basic use case for a successful authentication via Face VHAL is given as an
+exmple below.
+
+### Enabling VHAL
 
 ```shell
 $ adb root
-$ adb shell settings put secure com.android.server.biometrics.AuthService.hidlDisabled 1
-$ adb reboot
-```
-4. You should now be able to do fake enrollments and authentications (as seen down below)
-
-### Actual Device
-
-1. Modify your real devices make file (I.E. vendor/google/products/{YOUR_DEVICE}.mk)
-2. Ensure that there is no other face HAL that is being included by the device
-3. Add the following
-```
-PRODUCT_COPY_FILES += \
-    frameworks/native/data/etc/android.hardware.biometrics.face.xml:$(TARGET_COPY_OUT_PRODUCT)/etc/permissions/android.hardware.biometrics.face.xml
-
-PRODUCT_PACKAGES += \
-    android.hardware.biometrics.face-service.example \
-
-```
-4. Now build and flash m -j120 && flash
-5. Run the following commands
-
-```shell
-# This is a temporary workaround
-$ adb root
-$ adb shell setprop persist.vendor.face.virtual.type RGB
+$ adb shell device_config put biometrics_framework com.android.server.biometrics.face_vhal_feature true
+$ adb shell settings put secure biometric_virtual_enabled 1
 $ adb shell setprop persist.vendor.face.virtual.strength strong
-$ adb shell locksettings set-pin 0000
+$ adb shell setprop persist.vendor.face.virtual.type RGB
 $ adb reboot
 ```
 
-## Enrolling
+### Direct Enrollment
 
 ```shell
-# authenticar_id,bucket_id:duration:(true|false)....
-$ adb shell setprop vendor.face.virtual.next_enrollment 1,0:500:true,5:250:true,10:150:true,15:500:true
-$ adb shell am start -n com.android.settings/.biometrics.face.FaceEnrollIntroduction
-# If you would like to get rid of the enrollment, run the follwoing command
-$ adb shell setprop persist.vendor.face.virtual.enrollments \"\"
+$ adb shell locksettings set-pin 0000
+$ adb shell setprop persist.vendor.face.virtual.enrollments 1
+$ adb shell cmd face syncadb shell cmd face sync
 ```
 
 ## Authenticating
 
-```shell
-# If enrollment hasn't been setup
-$ adb shell setprop persist.vendor.face.virtual.enrollments 1
-$ adb shell cmd face sync
-# After enrollment has been setup
+To authenticate successfully, the captured (hit) must match the enrollment id<br/>
+set above. To trigger authentication failure, set the hit id to a different value.
+`shell
 $ adb shell setprop vendor.face.virtual.operation_authenticate_duration 800
-$ adb shell setprop vendor.face.virtual.enrollment_hit 1
-# Power button press to simulate auth
-$ adb shell input keyevent 26
+$ adb shell setprop vendor.face.virtual.enrollment_hit 1`
+
+### AcquiredInfo
+
+AcquiredInfo codes can be sent during authentication by specifying the sysprop.<br/>
+The codes is sent in sequence and in the interval of operation_authentication_duration/numberOfAcquiredInfoCode
+`shell
+$ adb shell setprop vendor.face.virtual.operation_authenticate_acquired 6,9,1013`
+Refer to [AcquiredInfo.aidl](https://source.corp.google.com/h/googleplex-android/platform/superproject/main/+/main:hardware/interfaces/biometrics/face/aidl/android/hardware/biometrics/face/AcquiredInfo.aidl) for full face acquiredInfo codes.
+Note: For vendor specific acquired info, acquiredInfo = 1000 + vendorCode.
+
+### Error Insertion
+
+Error can be inserted during authentction by specifying the authenticate_error
+sysprop. `shell $ adb shell setprop
+vendor.face.virtual.operation_authenticate_error 4` Refer to
+[Error.aidl](https://source.corp.google.com/h/googleplex-android/platform/superproject/main/+/main:hardware/interfaces/biometrics/face/aidl/android/hardware/biometrics/face/Error.aidl)
+for full face error codes
+
+## Enrollment via Settings
+
+Enrollment process is specified by sysprop `next_enrollment` in the following
+format
+
+```shell
+Format: <id>:<progress_ms-[acquiredInfo,...],...:<success>
+        ----:-----------------------------------:---------
+        |           |                               |--->sucess (true/false)
+        |           |--> progress_step(s)
+        |
+        |-->enrollment_id
+
+E.g.
+$ adb shell setprop vendor.face.virtual.next_enrollment 1:6000-[21,8,1,1108,1,10,1113,1,1118,1124]:true
 ```
+
+If next_enrollment prop is not set, the following default value is used:<br/>
+&nbsp;&nbsp;defaultNextEnrollment="1:1000-[21,7,1,1103],1500-[1108,1],2000-[1113,1],2500-[1118,1]:true"<br/>
+Note: Enrollment data and configuration can be supported upon request in case of needs
+
+## Lockout
+
+Device lockout is based on the number of consecutive failed authentication attempts. There are a few
+flavors of lockout mechanisms that are supported by virtula HAL <br/>
+
+### Permanent Lockout
+
+There are two sysprop to control permanent lockout <br/>
+1. general lockout feature enable <br/>
+2. threshold of failed attempts <br/>
+`shell
+$ adb shell setprop persist.vendor.face.virtual.lockout_enable true
+$ adb shell setprop persist.vendor.face.virtual.lockout_permanent_threshold 3`
+
+### Temporary Lockout
+
+There are a few parameters to control temporary lockout (aka timed lockout): <br/>
+1. enable lockout (general lockout feature enable, and timed lcokout enable) <br/>
+2. threshold of failed attempts <br/>
+3. timeout in ms <br/>
+`shell
+$ adb shell setprop persist.vendor.face.virtual.lockout_enable true
+$ adb shell setprop persist.vendor.face.virtual.lockout_timed_enable true
+$ adb shell setprop persist.vendor.face.virtual.lockout_timed_threshold 5
+$ adb shell setprop persist.vendor.face.virtual.lockout_timed_duration 10000`
+
+### Forced Lockout
+
+A permanent lockout can be inserted on next authentication attempt independent of the failed <br/>
+attempt count. This is a feature purely for test purpose.
+`shell
+$ adb shell setprop persist.vendor.face.virtual.lockout true`

+     * This means:

+// 2). this is a 'current' file. If you make a backwards compatible change to

+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking

-# Implement the 2.1 HAL instead!
+# Deprecated.
 
-It is strongly recommended that you implement the 2.1 HAL directly. See
-`hardware/interfaces/health/2.1/README.md` for more details.
+Health HIDL HAL 2.0 is deprecated and subject to removal. Please
+implement the Health AIDL HAL instead.
 
-# Upgrading from Health 1.0 HAL
-
-1. Remove `android.hardware.health@1.0*` from `PRODUCT_PACKAGES`
-   in `device/<manufacturer>/<device>/device.mk`
-
-1. If the device does not have a vendor-specific `libhealthd` AND does not
-   implement storage-related APIs, just do the following:
-
-   ```mk
-   PRODUCT_PACKAGES += android.hardware.health@2.0-service
-   ```
-
-   Otherwise, continue to the next step.
-
-1. Create directory
-   `device/<manufacturer>/<device>/health`
-
-1. Create `device/<manufacturer>/<device>/health/Android.bp`
-   (or equivalent `device/<manufacturer>/<device>/health/Android.mk`)
-
-    ```bp
-    cc_binary {
-        name: "android.hardware.health@2.0-service.<device>",
-        init_rc: ["android.hardware.health@2.0-service.<device>.rc"],
-        proprietary: true,
-        relative_install_path: "hw",
-        srcs: [
-            "HealthService.cpp",
-        ],
-
-        cflags: [
-            "-Wall",
-            "-Werror",
-        ],
-
-        static_libs: [
-            "android.hardware.health@2.0-impl",
-            "android.hardware.health@1.0-convert",
-            "libhealthservice",
-            "libbatterymonitor",
-        ],
-
-        shared_libs: [
-            "libbase",
-            "libcutils",
-            "libhidlbase",
-            "libutils",

-
-        overrides: [
-            "healthd",
-        ],
-    }
-    ```
-
-    1. (recommended) To remove `healthd` from the build, keep "overrides" section.
-    1. To keep `healthd` in the build, remove "overrides" section.
-
-1. Create `device/<manufacturer>/<device>/health/android.hardware.health@2.0-service.<device>.rc`
-
-    ```rc
-    service vendor.health-hal-2-0 /vendor/bin/hw/android.hardware.health@2.0-service.<device>
-        class hal
-        user system
-        group system
-        capabilities WAKE_ALARM
-        file /dev/kmsg w
-    ```
-
-1. Create `device/<manufacturer>/<device>/health/HealthService.cpp`:
-
-    ```c++
-    #include <health2/service.h>
-    int main() { return health_service_main(); }
-    ```
-
-1. `libhealthd` dependency:
-
-    1. If the device has a vendor-specific `libhealthd.<soc>`, add it to static_libs.
-
-    1. If the device does not have a vendor-specific `libhealthd`, add the following
-        lines to `HealthService.cpp`:
-
-        ```c++
-        #include <healthd/healthd.h>
-        void healthd_board_init(struct healthd_config*) {}
-
-        int healthd_board_battery_update(struct android::BatteryProperties*) {
-            // return 0 to log periodic polled battery status to kernel log
-            return 0;
-        }
-        ```
-
-1. Storage related APIs:
-
-    1. If the device does not implement `IHealth.getDiskStats` and
-        `IHealth.getStorageInfo`, add `libhealthstoragedefault` to `static_libs`.
-
-    1. If the device implements one of these two APIs, add and implement the
-        following functions in `HealthService.cpp`:
-
-        ```c++
-        void get_storage_info(std::vector<struct StorageInfo>& info) {
-            // ...
-        }
-        void get_disk_stats(std::vector<struct DiskStats>& stats) {
-            // ...
-        }
-        ```
-
-1. Update necessary SELinux permissions. For example,
-
-    ```
-    # device/<manufacturer>/<device>/sepolicy/vendor/file_contexts
-    /vendor/bin/hw/android\.hardware\.health@2\.0-service\.<device> u:object_r:hal_health_default_exec:s0
-
-    # device/<manufacturer>/<device>/sepolicy/vendor/hal_health_default.te
-    # Add device specific permissions to hal_health_default domain, especially
-    # if a device-specific libhealthd is used and/or device-specific storage related
-    # APIs are implemented.
-    ```
-
-1. Implementing health HAL in recovery. The health HAL is used for battery
-status checks during OTA for non-A/B devices. If the health HAL is not
-implemented in recovery, `is_battery_ok()` will always return `true`.
-
-    1. If the device does not have a vendor-specific `libhealthd`, nothing needs to
-    be done. A "backup" implementation is provided in
-    `android.hardware.health@2.0-impl-default`, which is always installed to recovery
-    image by default.
-
-    1. If the device does have a vendor-specific `libhealthd`, implement the following
-    module and include it in `PRODUCT_PACKAGES` (replace `<device>` with appropriate
-    strings):
-
-    ```bp
-    // Android.bp
-    cc_library_shared {
-        name: "android.hardware.health@2.0-impl-<device>",
-        recovery_available: true,
-        relative_install_path: "hw",
-        static_libs: [
-            "android.hardware.health@2.0-impl",
-            "libhealthd.<device>"
-            // Include the following or implement device-specific storage APIs
-            "libhealthstoragedefault",
-        ],
-        srcs: [
-            "HealthImpl.cpp",
-        ],
-        overrides: [
-            "android.hardware.health@2.0-impl-default",
-        ],
-    }
-    ```
-
-    ```c++
-    // HealthImpl.cpp
-    #include <health2/Health.h>
-    #include <healthd/healthd.h>
-    using android::hardware::health::V2_0::IHealth;
-    using android::hardware::health::V2_0::implementation::Health;
-    extern "C" IHealth* HIDL_FETCH_IHealth(const char* name) {
-        const static std::string providedInstance{"default"};
-        if (providedInstance != name) return nullptr;
-        return Health::initInstance(&gHealthdConfig).get();
-    }
-    ```
-
-    ```mk
-    # device.mk
-    PRODUCT_PACKAGES += android.hardware.health@2.0-impl-<device>
-    ```

+// This file is a snapshot of an AIDL file. Do not edit it manually. There are

+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will

+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+// This file is a snapshot of an AIDL file. Do not edit it manually. There are
+// two cases:
+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will
+//     prompt you to update this file with `m <name>-update-api`.
+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+# Security-Related HALs
+
+The `security/` subdirectory holds various security-related HALs.  (The final two sections of this
+document also describe security-related HALs that are in other places under `hardware/interfaces/`.)
+
+The most significant HAL is KeyMint (**`IKeyMintDevice`** in the
+`hardware/interfaces/security/keymint/` directory), which allows access to cryptographic
+functionality where the key material is restricted to a secure environment.  This functionality is
+used by Android system services, and is also made available to apps via Android Keystore.
+
+A KeyMint implementation (or an implementation of its predecessor, Keymaster) that runs in an
+isolated execution environment (e.g. ARM TrustZone) is required for most Android devices; see [CDD
+9.11](https://source.android.com/docs/compatibility/13/android-13-cdd#911_keys_and_credentials).
+
+A device may optionally also support a second KeyMint instance, running in a dedicated secure
+processor; this is known as StrongBox ([CDD
+9.11.2](https://source.android.com/docs/compatibility/13/android-13-cdd#9112_strongbox)).
+
+Two specific features of KeyMint are worth highlighting, as they have an impact on the other
+security-related HALs:
+
+- KeyMint supports keys that can only be used when the operation is authenticated by the user,
+  either by their lock screen knowledge factor (LSKF, e.g. PIN or pattern) or by a strong biometric
+  (e.g. fingerprint).
+- KeyMint supports *attestation* of public keys: when an asymmetric keypair is created, the secure
+  environment produces a chain of signed certificates:
+  - starting from a trusted root certificate
+  - terminating in a leaf certificate that holds the public key; this leaf certificate may also
+    describe the state of the device and the policies attached to the key.
+
+## Authentication Verification
+
+User authentication must also take place in a secure environment (see the final section below), but
+the results of that authentication are communicated to KeyMint via Android.  As such, the
+authentication result (a *hardware auth token*) is signed with a per-boot shared HMAC key known only
+to the secure components, so that it's authenticity can be verified.
+
+If an authenticator, for example GateKeeper (described by the **`IGatekeeper`** HAL in
+`hardware/interfaces/gatekeeper/`), is co-located in the same secure environment as KeyMint, it can
+use a local, vendor-specific, method to communicate the shared HMAC key.
+
+However, if the authenticator is in a different environment than the KeyMint instance then a local
+communication mechanism may not be possible.  For example, a StrongBox KeyMint instance running in a
+separate secure processor may not have a communication channel with a TEE on the main processor.
+
+To allow for this, the **`ISharedSecret`** HAL (in `hardware/interfaces/security/sharedsecret`)
+describes an N-party shared key agreement protocol for per-boot derivation of the shared HMAC key,
+based on a pre-provisioned shared secret.  This HAL can be implemented by any security component
+&ndash; whether KeyMint instance or authenticator &ndash; that needs access to the shared HMAC key.
+
+User authentication operations are also timestamped, but a StrongBox KeyMint instance may not have
+access to a secure time source that is aligned with the authenticator's time source.
+
+To allow for this, the **`ISecureClock`** HAL (in `hardware/interfaces/secureclock`) describes a
+challenge-based timestamp authentication protocol.  This HAL is optional; it need only be
+implemented if there is a KeyMint instance without a secure source of time.
+
+## Attestation Key Provisioning
+
+As noted above, key generation may also generate an attestation certificate chain, which requires
+that the secure environment have access to a signing key which in turn chains back to the Google
+root.
+
+Historically these signing keys were created by Google and provided to vendors for installation in
+batches of devices (to prevent their use as unique device identifiers).  However, this mechanism had
+significant disadvantages, as it required secure handling of key material and only allowed for
+coarse-grained revocation.
+
+The remote key provisioning HAL (**`IRemotelyProvisionedComponent`** in
+`hardware/interfaces/security/rkp/`) provides a mechanism whereby signing certificates for
+attestation can be retrieved at runtime from Google servers based on pre-registered device identity
+information.  This mechanism is used to provision certificates for KeyMint's signing keys, but is
+not restricted to that purpose; it can also be used in other scenarios where keys need to be
+provisioned (for example, for [Widevine](https://developers.google.com/widevine/drm/overview)).
+
+## Keymaster
+
+The Keymaster HAL (**`IKeymasterDevice`** in `hardware/interfaces/keymaster/`) is the historical
+ancestor of many of the HALs here (and may still be present on older devices).  Its functionality is
+effectively the union of the following current HALs:
+
+- **`IKeyMintDevice`**
+- **`ISharedSecret`**
+- **`ISecureClock`**
+
+## Related Authentication HALs
+
+Authentication of users needs to happen in a secure environment, using vendor-specific
+functionality, and so involves the use of one of the following HALs (all of which are outside the
+`security/` subdirectory).
+
+- The **`IGatekeeper`** HAL (in `hardware/interfaces/gatekeeper/`) provides user authentication
+  functionality based on the user's lock-screen knowledge factor (LSKF), including throttling
+  behaviour to prevent attacks.  Authentication tokens produced by this HAL are consumed by KeyMint,
+  validated using the shared HMAC key described above.
+  - The optional **`IWeaver`** HAL (in `hardware/interfaces/weaver`) improves the security of LSKF
+    authentication by converting the user's LSKF into a *synthetic password* via hashing and
+    stretching. This is required to be implemented on a separate secure element, which prevents
+    offline attacks on Gatekeeper storage. Note that Weaver does not directly interact with KeyMint;
+    the synthetic password is fed into Gatekeeper in place of the plain user password, and then
+    Gatekeeper interacts with KeyMint as normal.
+- The **`IFingerprint`** and **`IFace`** HAL definitions (under `hardware/interfaces/biometrics/`)
+  allow access to biometric authentication functionality that is implemented in a secure
+  environment.  Authentication tokens produced by these HALs are consumed by KeyMint, validated
+  using the shared HMAC key described above.
+- The optional **`IConfirmationUI`** HAL (in `hardware/interfaces/confirmationui`) supports
+  functionality where the user confirms that they have seen a specific message in a secure manner.
+  Confirmation tokens produced by this HAL are consumed by KeyMint, validated using the shared HMAC
+  key described above.

 To more securely and reliably get keys and certificates to Android devices, we
 need to create a system where no party outside of the device's secure components
 is responsible for managing private keys. The strategy we've chosen is to
-deliver certificates over the air, using an asymmetric key pair created
-on-device in the factory as a root of trust to create an authenticated, secure
-channel. In this document we refer to this device-unique asymmetric key pair as
-Device Key (DK), its public half DK\_pub, its private half DK\_priv and a Device
-Key Certificate containing DK\_pub is denoted DKC.
+deliver certificates over the air, using an asymmetric key pair derived from a
+unique device secret (UDS) as a root of trust for authenticated requests from
+the secure components. We refer to the public half of this asymmetric key pair
+as UDS\_pub.
 
-In order for the provisioning service to use DK (or a key authenticated by DK),
-it must know whether a given DK\_pub is known and trusted. To prove trust, we
-ask device OEMs to use one of two mechanisms:
+In order for the provisioning service to trust UDS\_pub we ask device OEMs to
+use one of two mechanisms:
 
-1.  (Preferred, recommended) The device OEM extracts DK\_pub from each device it
-    manufactures and uploads the public keys to a backend server.
+1.  (Preferred, recommended) The device OEM extracts the UDS\_pub from each
+    device they manufacture and uploads the public keys to a backend server.
 
-1.  The device OEM signs the DK\_pub to produce DKC and stores it on the device.
-    This has the advantage that they don't need to upload a DK\_pub for every
-    device immediately, but the disadvantage that they have to manage their
-    private signing keys, which means they have to have HSMs, configure and
-    secure them correctly, etc. Some backend providers may also require that the
-    OEM passes a factory security audit, and additionally promises to upload the
-    keys eventually as well.
+1.  The device OEM signs the UDS\_pub and stores the certificates on the device
+    rather than uploading a UDS\_pub for every device immediately. However,
+    there are many disadvantages and costs associated with this option as the
+    OEM will need to pass a security audit of their factory's physical security,
+    CA and HSM configuration, and incident response processes before the OEM's
+    public key is registered with the provisioning server.
 
-Note that in the full elaboration of this plan, DK\_pub is not the key used to
-establish a secure channel. Instead, DK\_pub is just the first public key in a
-chain of public keys which ends with the KeyMint public key, KM\_pub. All keys
-in the chain are device-unique and are joined in a certificate chain called the
-_Boot Certificate Chain_ (BCC), because in phases 2 and 3 of the remote
-provisioning project it is a chain of certificates corresponding to boot phases.
-We speak of the BCC even for phase 1, though in phase 1 it contains only a
-single self-signed DKC. This is described in more depth in the Phases section
-below.
+Note that in the full elaboration of this plan, UDS\_pub is not the key used to
+sign certificate requests. Instead, UDS\_pub is just the first public key in a
+chain of public keys that end the KeyMint public key. All keys in the chain are
+transitively derived from the UDS and joined in a certificate chain following
+the specification of the [Android Profile for DICE](android-profile-for-dice).
 
-The BCC is authenticated by DK\_pub. To authenticate DK\_pub, we may have
-additional DKCs, from the SoC vendor, the device OEM, or both. Those are not
-part of the BCC but included as optional fields in the certificate request
-structure.
-
-The format of the the DK and BCC is specified within [Open Profile for DICE]
-(https://pigweed.googlesource.com/open-dice/+/HEAD/docs/specification.md).  To
-map phrases within this document to their equivalent terminology in the DICE
-specification, read the terms as follows: the DK corresponds to the UDS-derived
-key pair, DKC corresponds to the UDS certificate, and the BCC entries between
-DK\_pub and KM\_pub correspond to a chain of CDI certificates.
-
-Note: In addition to allowing 32 byte hash values for fields in the BCC payload,
-this spec additionally constrains some of the choices allowed in open-DICE.
-Specifically, these include which entries are required and which are optional in
-the BCC payload, and which algorithms are acceptable for use.

 ### Phases
 
-RKP will be deployed in three phases, in terms of managing the root of trust
+RKP will be deployed with phased management of the root of trust
 binding between the device and the backend. To briefly describe them:
 
-* Phase 1: In phase 1 there is only one entry in the BCC; DK_pub and KM_pub are
-  the same key and the certificate is self-signed.
-* Phase 2: This is identical to phase 1, except it leverages the hardware root
-  of trust process described by DICE. Instead of trust being rooted in the TEE,
-  it is now rooted in the ROM by key material blown into fuses which are only
-  accessible to the ROM code.
-* Phase 3: This is identical to Phase 2, except the SoC vendor also does the
-  public key extraction or certification in their facilities, along with the OEM
-  doing it in the factory. This tightens up the "supply chain" and aims to make
-  key upload management more secure.
+* Degenerate DICE (Phase 1): A TEE root of trust key pair is used to sign
+  certificate requests; a single self-signed certificate signifies this phase.
+* DICE (Phase 2): A hardware root of trust key pair is only accessible to ROM
+  or ROM extension code; the boot process follows the [Android Profile for
+  DICE](android-profile-for-dice).
+* SoC vendor certified DICE (Phase 3): This is identical to Phase 2, except the
+  SoC vendor also does the UDS\_pub extraction or certification in their
+  facilities, along with the OEM doing it in the factory. This tightens up the
+  "supply chain" and aims to make key upload management more secure.
 
 ### Privacy considerations
 
-Because DK and the DKCs are unique, immutable, unspoofable hardware-bound
-identifiers for the device, we must limit access to them to the absolute minimum
-possible. We do this in two ways:
-
-1.  We require KeyMint (which knows the BCC and either knows or at least has the
-ability to use KM\_priv) to refuse to ever divulge the BCC or additional
-signatures in plaintext. Instead, KeyMint requires the caller to provide an
-_Endpoint Encryption Key_ (EEK), with which it will encrypt the data before
-returning it. When provisioning production keys, the EEK must be signed by an
-approved authority whose public key is embedded in KeyMint. When certifying test
-keys, KeyMint will accept any EEK without checking the signature, but will
-encrypt and return a test BCC, rather than the real one.  The result is that
-only an entity in possession of an Trusted EEK (TEEK) private key can discover

-approach and mechanisms for doing that are beyond the scope of this document
-(they must be addressed in the server design), but generally involve taking care
-to ensure that we do not create any links between user IDs, IP addresses or
-issued certificates and the device pubkey.
-
-Although the details of the mechanisms for preventing the entity from abusing
-the BCC are, as stated, beyond the scope of this document, there is a subtle
-design decision here made specifically to enable abuse prevention. Specifically
-the `CertificateRequest` message sent to the server is (in
-[CDDL](https://tools.ietf.org/html/rfc8610)):
-
-```
-cddl
-CertificateRequest = [
-    DeviceInfo,
-    challenge : bstr,
-    ProtectedData,
-    MacedKeysToSign
-]
-```
-
-The public keys to be attested by the server are in `MacedKeysToSign`, which is
-a COSE\_Mac0 structure, MACed with a key that is found in `ProtectedData`. The
-MAC key is signed by DK\_pub.
-
-This structure allows the backend component that has access to EEK\_priv to
-decrypt `ProtectedData`, validate that the request is from an authorized device,
-check that the request is fresh and verify and extract the MAC key. That backend
-component never sees any data related to the keys to be signed, but can provide
-the MAC key to another backend component that can verify `MacedKeysToSign` and
-proceed to generate the certificates.
-
-In this way, we can partition the provisioning server into one component that
-knows the device identity, as represented by DK\_pub, but never sees the keys to
-be certified or certificates generated, and another component that sees the keys
-to be certified and certificates generated but does not know the device
-identity.
+Because the UDS, CDIs and derived values are unique, immutable, unspoofable
+hardware-bound identifiers for the device, we must limit access to them. We
+require that the values are never exposed in public APIs and are only available
+to the minimum set of system components that require access to them to function
+correctly.

-It's critical that the remote provisioning implementation be testable, to
-minimize the probability that broken devices are sold to end users. To support
-testing, the remote provisioning HAL methods take a `testMode` argument. Keys
-created in test mode are tagged to indicate this. The provisioning server will
-check for the test mode tag and issue test certificates that do not chain back

-validate the content of certificate requests. The BCC included in the
-`CertificateRequest` must contain freshly-generated keys, not the real BCC keys.
-
-Keystore (or similar) will need to be able to handle both testMode keys and
-production keys and keep them distinct, generating test certificate requests
-when asked with a test EEK and production certificate requests when asked with a

-### `BCC`
-
-The _Boot Certificate Chain_ (BCC) is the chain of certificates that contains
-DK\_pub as well as other often device-unique certificates. The BCC is
-represented as a COSE\_Key containing DK\_pub followed by an array of
-COSE\_Sign1 "certificates" containing public keys and optional additional
-information, ordered from root to leaf, with each certificate signing the next.
-The first certificate in the array is signed by DK\_pub, the last certificate
-has the KeyMint (or whatever) signing key's public key, KM\_pub. In phase 1
-there is only one entry; DK\_pub and KM\_pub are the same key and the
-certificate is self-signed.
-
-Each COSE\_Sign1 certificate is a CBOR Web Token (CWT) as described in [RFC
-8392](https://tools.ietf.org/html/rfc8392) with additional fields as described
-in the Open Profile for DICE. Of these additional fields, only the
-_subjectPublicKey_ and _keyUsage_ fields are expected to be present for the
-KM\_pub entry (that is, the last entry) in a BCC, but all fields required by the
-Open Profile for DICE are expected for other entries (each of which corresponds
-to a particular firmware component or boot stage). The CWT fields _iss_ and
-_sub_ identify the issuer and subject of the certificate and are consistent
-along the BCC entries; the issuer of a given entry matches the subject of the
-previous entry.
-
-The BCC is designed to be constructed using the Open Profile for DICE. In this
-case the DK key pair is derived from the UDS as described by that profile and
-all BCC entries before the leaf are CBOR CDI certificates chained from DK\_pub.
-The KM key pair is not part of the derived DICE chain. It is generated (not
-derived) by the KeyMint module, certified by the last key in the DICE chain, and
-added as the leaf BCC entry. The key usage field in this leaf certificate must
-indicate the key is not used to sign certificates. If a UDS certificate is
-available on the device it should appear in the certificate request as the leaf
-of a DKCertChain in AdditionalDKSignatures (see
-[CertificateRequest](#certificaterequest)).
-
-#### Mode
-
-The Open Profile for DICE specifies four possible modes with the most important
-mode being `normal`. A certificate must only set the mode to `normal` when all
-of the following conditions are met when loading and verifying the software
-component that is being described by the certificate:
-
-*   verified boot with anti-rollback protection is enabled
-*   only the verified boot authorities for production images are enabled
-*   debug ports, fuses or other debug facilities are disabled
-*   device booted software from the normal primary source e.g. internal flash
-
-If any of these conditions are not met then it is recommended to explicitly
-acknowledge this fact by using the `debug` mode. The mode should never be `not
-configured`.
-
-#### Configuration descriptor
-
-The Open Profile for DICE allows for an arbitrary configuration descriptor. For
-BCC entries, this configuration descriptor is a CBOR map with the following
-optional fields. If no fields are relevant, an empty map should be encoded.
-Additional implementation-specific fields may be added using key values not in
-the range \[-70000, -70999\] (these are reserved for future additions here).

+### Support for Android Virtualization Framework
+
+The Android Virtualization Framwork (AVF) relies on RKP to provision keys for VMs. A
+privileged vm, the RKP VM, is reponsible for generating and managing the keys for client
+VMs that run virtualized workloads. See the following for more background information on the
+RKP VM:
+*    [rkp-vm](https://android.googlesource.com/platform/packages/modules/Virtualization/+/main/service_vm/README.md#rkp-vm-remote-key-provisioning-virtual-machine)
+*    [rkp-service](https://source.android.com/docs/core/ota/modular-system/remote-key-provisioning#stack-architecture)
+
+It is important to distinquish the RKP VM from other components, such as KeyMint. An
+[RKP VM marker](https://pigweed.googlesource.com/open-dice/+/HEAD/docs/android.md#configuration-descriptor)
+(key `-70006) is used for this purpose. The existence or absence of this marker is used to
+identify the type of component decribed by a given DICE chain.
+
+The following describes which certificate types may be request based on the RKP VM marker:
+1. "rkp-vm": If a DICE chain has zero or more certificates without the RKP VM
+   marker followed by one or more certificates with the marker, then that chain
+   describes an RKP VM. If there are further certificates without the RKP VM
+   marker, then the chain does not describe an RKP VM.
+
+   Implementations must include the first RKP VM marker as early as possible
+   after the point of divergence between TEE and non-TEE components in the DICE
+   chain, prior to loading the Android Bootloader (ABL).
+2. "widevine" or "keymint": If there are no certificates with the RKP VM
+   marker then it describes a TEE component.
+3. None: Any component described by a DICE chain that does not match the above
+   two categories.

+// This file is a snapshot of an AIDL file. Do not edit it manually. There are
+// two cases:
+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will
+//     prompt you to update this file with `m <name>-update-api`.
+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+// This file is a snapshot of an AIDL file. Do not edit it manually. There are
+// two cases:
+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will
+//     prompt you to update this file with `m <name>-update-api`.
+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.
