+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,
+//                    const std::vector<AudioDevice>& devices);
+//   };
+//

 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.
-
-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.
+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).
 
 ### 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

-### `BCC`
+### Android Profile for DICE
 
-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.
+The Android Profile for DICE is based on the [Open Profile for
+DICE](https://pigweed.googlesource.com/open-dice/+/refs/heads/main/docs/specification.md),
+with additional constraints for details that the Open Profile for DICE leaves
+intentionally underspecified. This section describes the differences from the
+Open Profile for DICE.
 
-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.
+#### Algorithms
 
-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)).
+The choice of algorithm must remain consistent with a given certificate e.g. if
+SHA-256 is used for the code hash then the authority hash, config hash, etc.
+must also use SHA-256.
+
+* UDS and CDI key pairs:
+  * Ed25519 / P-256 / P-384
+* Hash algorithms (digests can be encoded with their natural size and do not
+  need to be the 64-bytes specified by the Open Profile for DICE):
+  * SHA-256 / SHA-384 / SHA-512
+* HKDF with a supported message digest for all key derivation
 
 #### 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:
+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

-*   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
+* 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

-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`.
+The mode should never be `not configured`.
+
+Every certificate in the DICE chain will need to be have the `normal` mode in
+order to be provisioned with production certificates by RKP.
 
 #### 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).

-The directory includes the unstable/unreleased version of `hardware/interfaces/threadnetwork`
-code which should **NOT** be used in production. But vendors may start verifying their hardware
-with the HAL interface.
-
-This directory will be cleaned up when the stable Thread HAL interface is added in
-`hardware/interfaces/threadnetwork` by version `V` or later.
