+// You must not make a backward incompatible change to any AIDL file built

+// 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

+// Note: When transitioning to loading of XML configs, either keep the configuration
+// of the remote submix sources from this static configuration, or update the XML
+// config to match it. There are several reasons for that:
+//   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
+//      XML file lacks this specification.

+namespace aidl::android::hardware::audio::core {
+
+// 'StreamSwitcher' is an implementation of 'StreamCommonInterface' which allows
+// dynamically switching the underlying stream implementation based on currently
+// connected devices. This is achieved by replacing inheritance from
+// 'StreamCommonImpl' with owning an instance of it. StreamSwitcher must be
+// extended in order to supply the logic for choosing the stream
+// implementation. When there are no connected devices, for instance, upon the
+// creation, the StreamSwitcher engages an instance of a stub stream in order to
+// keep serving requests coming via 'StreamDescriptor'.
+//
+// StreamSwitcher implements the 'IStreamCommon' interface directly, with
+// necessary delegation to the current stream implementation. While the stub
+// stream is engaged, any requests made via 'IStreamCommon' (parameters, effects
+// setting, etc) are postponed and only delivered on device connection change
+// to the "real" stream implementation provided by the extending class. This is why
+// the behavior of StreamSwitcher in the "stub" state is not identical to behavior
+// of 'StreamStub'. It can become a full substitute for 'StreamStub' once
+// device connection change event occurs and the extending class returns
+// 'LEAVE_CURRENT_STREAM' from 'switchCurrentStream' method.
+//
+// There is a natural limitation that the current stream implementation may only
+// be switched when the stream is in the 'STANDBY' state. Thus, when the event
+// to switch the stream occurs, the current stream is stopped and joined, and
+// its last state is validated. Since the change of the set of connected devices
+// normally occurs on patch updates, if the stream was not in standby, this is
+// reported to the caller of 'IModule.setAudioPatch' as the 'EX_ILLEGAL_STATE'
+// error.
+//
+// The simplest use case, when the implementor just needs to emulate the legacy HAL API
+// behavior of receiving the connected devices upon stream creation, the implementation
+// of the extending class can look as follows. We assume that 'StreamLegacy' implementation
+// is the one requiring to know connected devices on creation:
+//
+//   class StreamLegacy : public StreamCommonImpl {
+//     public:
+//       StreamLegacy(StreamContext* context, const Metadata& metadata,

+# 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
-the plaintext of the production BCC.
-1.  Having thus limited access to the public keys to the trusted party only, we
-need to prevent the entity from abusing this unique device identifier.  The
-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.

-### Testability
-
-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
-to a trusted public key. In test mode, any EEK will be accepted, enabling
-testing tools to use EEKs for which they have the private key so they can
-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
-production EEK. Likewise, the interface used to instruct Keystore to create keys
-will need to be able to specify whether test or production keys are desired.

-### `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 RPK 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.

+/**
+ * Secretkeeper service definition.
+ *
+ * An ISecretkeeper instance provides secure storage of secrets on behalf of other components in
+ * Android, in particular for protected virtual machine instances. From the perspective of security
+ * privilege, Secretkeeper must be implemented in an environment with privilege higher than any of
+ * its clients. Since AVF based protected Virtual Machines are one set of its clients, the
+ * implementation of ISecretkeeper should live in a secure environment, such as:
+ * - A trusted execution environment such as ARM TrustZone.
+ * - A completely separate, purpose-built and certified secure CPU.
+ *
+ * TODO(b/291224769): Extend the HAL interface to include:
+ * 1. Session setup api: This is used to perform cryptographic operations that allow shared keys to
+ * be exchanged between session participants, typically (but not necessarily) a pVM instance and
+ * Secretkeeper. This session setup is based on public key cryptography.
+ * 2. Dice policy operation - These allow sealing of the secrets with a class of Dice chains.
+ * Typical operations are (securely) updating the dice policy sealing the Secrets above. These
+ * operations are core to AntiRollback protected secrets - ie, ensuring secrets of a pVM are only
+ * accessible to same or higher versions of the images.
+ * 3. Maintenance api: This is required for removing the Secretkeeper entries for obsolete pvMs.

+     * Secret Management API: The clients can use this API to store (& get) 32 bytes of data.
+     * The API is a CBOR based protocol, which follows request/response model.
+     * See SecretManagement.cddl for the API spec.
+     *
+     * Further, the requests (from client) & responses (from service) must be encrypted into
+     * ProtectedRequestPacket & ProtectedResponsePacket using symmetric keys agreed between
+     * the client & service. This cryptographic protection is required because the messages are
+     * ferried via Android, which is allowed to be outside the TCB of clients (for example protected
+     * Virtual Machines). For this, service (& client) must implement a key exchange protocol, which
+     * is critical for establishing the secure channel.
+     *
+     * Secretkeeper database should guarantee the following properties:
+     * 1. Confidentiality: No entity (of security privilege lower than Secretkeeper) should
+     *    be able to get a client's data in clear.
+     *
+     * 2. Integrity: The data is protected against malicious Android OS tampering with database.
+     *    ie, if Android (userspace & kernel) tampers with the client's secret, the Secretkeeper
+     *    service must be able to detect it & return error when clients requests for their secrets.
+     *    Note: the integrity requirements also include Antirollback protection ie, reverting the
+     *    database into an old state should be detected.
+     *
+     * 3. The data is persistent across device boot.
+     *    Note: Denial of service is not in scope. A malicious Android may be able to delete data,
+     *    but for ideal Android, the data should be persistent.
