+     *
+     * This method computes the shared 32-byte HMAC ``H'' as follows (all Keymaster instances
+     * perform the same computation to arrive at the same result):
+     *
+     *     H = CKDF(key = K,
+     *              context = P1 || P2 || ... || Pn,
+     *              label = "KeymasterSharedMac")
+     *
+     * where:
+     *
+     *     ``CKDF'' is the standard AES-CMAC KDF from NIST SP 800-108 in counter mode (see Section
+     *           5.1 of the referenced publication).  ``key'', ``context'', and ``label'' are
+     *           defined in the standard.  The counter is prefixed, as shown in the construction on
+     *           page 12 of the standard.  The label string is UTF-8 encoded.
+     *
+     *     ``K'' is a pre-established shared secret, set up during factory reset.  The mechanism for
+     *           establishing this shared secret is implementation-defined, but see below for a
+     *           recommended approach, which assumes that the TEE Keymaster does not have storage
+     *           available to it, but the StrongBox Keymaster does.
+     *
+     *           <b>CRITICAL SECURITY REQUIREMENT</b>: All keys created by a Keymaster instance must
+     *           be cryptographically bound to the value of K, such that establishing a new K
+     *           permanently destroys them.
+     *
+     *     ``||'' represents concatenation.
+     *
+     *     ``Pi'' is the i'th HmacSharingParameters value in the params vector.  Note that at
+     *           present only two Keymaster implementations are supported, but this mechanism
+     *           extends without modification to any number of implementations.  Encoding of an
+     *           HmacSharingParameters is the concatenation of its two fields, i.e. seed || nonce.
+     *
+     * Process for establishing K:
+     *
+     *     Any method of securely establishing K that ensures that an attacker cannot obtain or
+     *     derive its value is acceptable.  What follows is a recommended approach, to be executed
+     *     during each factory reset.  It relies on use of the factory-installed attestation keys to
+     *     mitigate man-in-the-middle attacks.  This protocol requires that one of the instancess
+     *     have secure persistent storage.  This model was chosen because StrongBox has secure
+     *     persistent storage (by definition), but the TEE may not.  The instance without storage is
+     *     assumed to be able to derive a unique hardware-bound key (HBK) which is used only for
+     *     this purpose, and is not derivable outside of the secure environment..
+     *
+     *     In what follows, T is the Keymaster instance without storage, S is the Keymaster instance
+     *     with storage:
+     *
+     *     1. T generates an ephemeral EC P-256 key pair K1
+     *     2. T sends K1_pub to S, signed with T's attestation key.
+     *     3. S validates the signature on K1_pub.
+     *     4. S generates an ephemeral EC P-256 key pair K2.
+     *     5. S sends {K1_pub, K2_pub}, to T, signed with S's attestation key.
+     *     6. T validates the signature on {K1_pub, K2_pub}
+     *     7. T uses {K1_priv, K2_pub} with ECDH to compute session secret Q.
+     *     8. T generates a random seed S
+     *     9. T computes K = KDF(HBK, S), where KDF is some secure key derivation function.
+     *     10. T sends M = AES-GCM-ENCRYPT(Q, {S || K}) to S.
+     *     10. S uses {K2_priv, K1_pub} with ECDH to compute session secret Q.
+     *     11. S computes S || K = AES-GCM-DECRYPT(Q, M) and stores S and K.
+     *
+     *     When S receives the getHmacSharingParameters call, it returns the stored S as the seed
+     *     and a nonce.  When T receives the same call, it returns an empty seed and a nonce.  When
+     *     T receives the computeSharedHmac call, it uses the seed provided by S to compute K.  S,
+     *     of course, has K stored.

+     *
+     *         The string is UTF-8 encoded.  If the returned values of all Keymaster instances don't
+     *         match, Keystore will assume that HMAC agreement failed.

+/**
+ * This header contains various definitions that make working with keymaster tags safer and easier.
+ *
+ * It makes use of a fair amount of template metaprogramming. The metaprogramming serves the purpose
+ * of making it impossible to make certain classes of mistakes when operating on keymaster
+ * authorizations.  For example, it's an error to create a KeyParameter with tag == Tag::PURPOSE
+ * and then to assign Algorithm::RSA to algorithm element of its union. But because the user
+ * must choose the union field, there could be a mismatch which the compiler has now way to
+ * diagnose.
+ *
+ * The machinery in this header solves these problems by describing which union field corresponds
+ * to which Tag. Central to this mechanism is the template TypedTag. It has zero size and binds a
+ * numeric Tag to a type that the compiler understands. By means of the macro DECLARE_TYPED_TAG,
+ * we declare types for each of the tags defined in hardware/interfaces/keymaster/4.0/types.hal.
+ *
+ * The macro DECLARE_TYPED_TAG(name) generates a typename TAG_name_t and a zero sized instance
+ * TAG_name. Once these typed tags have been declared we define metafunctions mapping the each tag
+ * to its value c++ type and the correct union element of KeyParameter. This is done by means of
+ * the macros MAKE_TAG_*VALUE_ACCESSOR, which generates TypedTag2ValueType, a metafunction mapping
+ * a typed tag to the corresponding c++ type, and access function, accessTagValue returning a
+ * reference to the correct element of KeyParameter.
+ * E.g.:
+ *      given "KeyParameter param;" then "accessTagValue(TAG_PURPOSE, param)"
+ *      yields a reference to param.f.purpose
+ * If used in an assignment the compiler can now check the compatibility of the assigned value.
+ *
+ * For convenience we also provide the constructor like function Authorization().
+ * Authorization takes a typed tag and a value and checks at compile time whether the value given
+ * is suitable for the given tag. At runtime it creates a new KeyParameter initialized with the
+ * given tag and value and returns it by value.
+ *
+ * The second convenience function, authorizationValue, allows access to the KeyParameter value in
+ * a safe way. It takes a typed tag and a KeyParameter and returns a reference to the value wrapped
+ * by NullOr. NullOr has out-of-band information about whether it is save to access the wrapped
+ * reference.
+ * E.g.:
+ *      auto param = Authorization(TAG_ALGORITM, Algorithm::RSA);
+ *      auto value1 = authorizationValue(TAG_PURPOSE, param);
+ *      auto value2 = authorizationValue(TAG_ALGORITM, param);
+ * value1.isOk() yields false, but value2.isOk() yields true, thus value2.value() is save to access.

+     *       control of and access to a high-quality TRNG which it uses for generating necessary
+     *       random bits.  It must combine the output of this TRNG with caller-provided entropy in a
+     *       strong CPRNG, as do non-Strongbox Keymaster implementations.
+     *
+     *    d) Is enclosed in tamper-resistant packaging.  The StrongBox device must have

+     *       higher than those provided by normal integrated circuit packages.
+     *
+     *    e) Provides side-channel resistance.  The StrongBox device must implement resistance
+     *       against common side-channel attacks, including power analysis, timing analysis, EM
+     *       snooping, etc.
+     *
+     * Devices with StrongBox Keymasters must also have a non-StrongBox Keymaster, which lives in
+     * the higher-performance TEE.  Keystore must load both StrongBox (if available) and
+     * non-StrongBox HALs and route key generation/import requests appropriately.  Callers that want
+     * StrongBox keys must add Tag::HARDWARE_TYPE with value SecurityLevel::STRONGBOX to the key
+     * description provided to generateKey or importKey.  Keytore must route the request to a
+     * StrongBox HAL (a HAL whose isStrongBox method returns true).  Keymaster implementations that
+     * receive a request for a Tag::HARDWARE_TYPE that is inappropriate must fail with
+     * ErrorCode::HARDWARE_TYPE_UNAVAILABLE.
