     *           defined in the standard.  The counter is prefixed and length L appended, 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.Any method of securely

     *           establishing K that ensures that an attacker cannot obtain or derive its value is

     *           acceptable.

     *           CRITICAL SECURITY REQUIREMENT: All keys created by a IKeymintDevice instance must

     *           be cryptographically bound to the value of K, such that establishing a new K

     *           permanently destroys them.
