+/**
+ * This is the interface to be implemented by an AuthMgr backend component (AuthMgr BE), in order to
+ * allow the AuthMgr frontend component (AuthMgr FE) in a pVM instance to authenticate itself and
+ * to authorize one or more clients in the pVM instance, in order to let the clients access
+ * trusted services in the Trusted Execution Environment (TEE).
+ *
+ * The following assumptions must be true for the underlying IPC mechanism and the transport layer:
+ *     1. Both parties should be able to retrieve a non-spoofable identifier of the other party from
+ *        the transport layer (a.k.a transport ID or vM ID), which stays the same throughout a given
+ *        boot cycle of a pVM instance. This is important to prevent person-in-the-middle (PITM)
+ *        attacks and to authorize a new connection from a pVM instance based on an already
+ *        authenicated connection from the same pVM instance.
+ *
+ *     2. Each of AuthMgr FE and the AuthMgr BE should be able to hand over a connection that is
+ *        setup between them to another party so that such connection can be used for communication
+ *        between the two new parties subsequently. This is important to be able to handover an
+ *        authorized connection established between the AuthMgr FE and the AuthMgr BE to a client in
+ *        in a pVM instance and a trusted service in TEE respectively.
+ *
+ *     3. This API should be exposed over an IPC mechanism that supports statefull connections. This
+ *        is important for the AuthMgr FE to setup an authenicated connection once per boot cycle
+ *        and reuse it to authorize multiple client connections afterwards, if needed.
+ *
+ *      4. AuthMgr FE has a mechanism for discovering and establishing a connection to the trusted
+ *         AuthMgr BE. Based on this assumptionson, mutual authentication is not covered by this
+ *         API.
+ *
+ * The AuthMgr authorization protocol consists of two phases:
+ *     1. Phase 1 authenticates the AuthMgr FE to the AuthMgr BE via the first two methods of this
+ *        API: `initAuthentication` and `completeAuthentication`. At the end of the successful
+ *        excecution of phase 1, the AuthMgr FE and the AuthMgr BE have an authenticated connection
+ *        established between them. Phase 1 also enforces rollback protection on AuthMgr FE in
+ *        addition to authentication.
+ *
+ *        Authentication is performed by verifying the AuthMgr FE's signature on the challenge
+ *        issued by the AuthMgr BE. The public signing key of the AuthMgr FE is obtained from the
+ *        validated DICE certificate chain for verifying the signature. Rollback protection is
+ *        enforced by matching the DICE certificate chain against the stored DICE policy.
+ *        AuthMgr FE uses this authenticated connection throughout the boot cycle of the pVM to send
+ *        phase 2 requests to the AuthMgr BE. Therefore, phase 1 needs to be executed only once per
+ *        boot cycle of the pVM. AuthMgr BE should take measures to prevent any duplicate
+ *        authentication attempts from the same instance or from any impersonating instances.
+ *
+ *     2. Phase 2 authorizes a client in the pVM to access trusted service(s) in the TEE and
+ *        establishes a new connection between the client and the trusted service based on the trust
+ *        in the authenticated connection established in phase 1. The client and the trusted service
+ *        can communicate independently from the AuthMgr(s) after the successful execution of
+ *        phase 2 of the authorization protocol.
+ *
+ *        The AuthMgr FE first opens a new vsock connection to the AuthMgr BE and sends a one-time
+ *        token over that connection. The AuthMgr FE then invokes the third method of this API
+ *        (`authorizeAndConnectClientToTrustedService`) on the authenticated connection established
+ *        with the AuthMgr BE in phase 1. Rollback protection is enforced on the client by matching
+ *        the client's DICE certificate against the stored DICE policy. The new connection is
+ *        authorized by matching the token sent over the new connection and the token sent over the
+ *        authenicated connection.
+ *
+ * AuthMgr BE should make sure that "use-after-destroy" threats are prevented in the implementation
+ * of this authorization protocol. This means that even if a client/pVM instance is created with the
+ * same identifier(s) of a deleted client/pVM instance, the new client should not be able to access
+ * the deleted client's secrets/resources created in the trusted services. The following
+ * requirements should be addressed in order to ensure this:
+ * 1) Each client should be identified by a unique identifier at the AuthMgr BE. The uniqueness
+ *    should be guaranteed across factory resets.
+ * 2) The client's unique identifier should be used when constructing the file path to store the
+ *    client's context, including the client's DICE policy, in the AuthMgr BE's secure storage.
+ * 3) The client's unique identifier should be conveyed to the trusted service(s) that the client
+ *    accesses, when an authorized connection is setup between the client and the trusted service in
+ *    phase 2. The trusted service(s) should mix in this unique client identifier when providing the
+ *    critical services to the clients (e.g. deriving HW-backed keys by the HWCrypto service,
+ *    storing data by the SecureStorage service).
+ *
+ * An example approach to build a unique identifier for a client is as follows:
+ * The AuthMgr BE stores a `global sequence number` in the secure storage that does not get
+ * wiped upon factory reset. Everytime the AuthMgr BE sees a new instance or a client, it assigns
+ * the current `global sequence number` as the unique sequence number of the instance or the client
+ * and increments the `global sequence number`.

+     * The AuthMgr FE then invokes this method on the authenticated connection established with the
+     * AuthMgr BE in phase 1. When this method is invoked, the AuthMgr BE checks whether the
+     * underlying connection of this method call is already authenticated.
+     *
+     * The AuthMgr FE acts as the DICE manager for all the clients in the pVM and generates the DICE
+     * leaf certificate and the DICE leaf policy for the client, which are sent in the input:
+     * `clientDiceArtifacts`.
+     *
+     * The AuthMgr BE matches the client's DICE leaf certificate to the client's DICE policy.
+     * If this is the first invocation of this method in the lifetime of the client, the AuthMgr BE
+     * stores the client's DICE policy in the secure storage as part of the client's context, upon
+     * successful matching of the DICE certificate to the policy. The file path for the storage of
+     * the client's context should be constructed using the unique id assigned to the pVM instance
+     * by the AuthMgr BE (e.g. instance sequence number)  and the client ID. There is no use
+     * case for deleting a client context or a pVM context created in the secure storage, for the
+     * first version of this API, outside of the factory reset. In the future, we expect to
+     * expose APIs for those tasks.
+     *
+     * In the subsequent invocations of this method, the AuthMgr BE matches the given DICE leaf
+     * certificate to the stored DICE policy in order to enforce rollback protection. If that
+     * succeeds and if the given DICE policy is different from the stored DICE policy, the AuthMgr
+     * BE replaces the stored DICE policy with the given DICE policy.
+     *
+     * If the same client requests multiple trusted services or connects to the same trusted service
+     * multiple times during the same boot cycle of the pVM instance, it is recommended to validate
+     * the client's DICE artifacts only once for a given client as an optimization.
+     *
+     * The AuthMgr BE keeps track of the aforementioned new connections that are pending
+     * authorization along with the tokens sent over them and the transport ID of the pVM instance
+     * which created those connections.
+     *
+     * The AuthMgr FE sends the same token that was sent over an aforementioned new connection
+     * in the input: `token` of this method call, in order to authorize the new connection, based on
+     * the trust in the authenticated connection established in phase 1.
+     *
+     * Once the validation of the client's DICE artifacts is completed, the AuthMgr BE retrieves the
+     * pending new connection to be authorized, which is associated with a token that matches the
+     * token sent in this method call and a transport ID that matches the transport ID associated
+     * with the connection underlying this method call.
+     *
+     * Next the AuthMgr BE connects to the trusted service requested by the client in order to
+     * handover the new authorized connection to the trusted service. Once the connection
+     * handover is successful, the AuthMgr BE returns OK to the AuthMgr FE. Then the AuthMgr FE
+     * returns to the client a handle to the new connection (created at the beginning of phase 2).
+     * At this point, an authorized connection is setup between the client and the trusted service,
+     * which they can use to communicate independently of the AuthMgr FE and the AuthMgr BE.
