A \keyTuple $(\AuthPrivate, \TransmitPrivate, \PaymentAddress)$ is
generated by users who wish to receive payments under this scheme.
Users who wish to receive payments under this scheme first generate a
random \spendingKey $\AuthPrivate$.
The \receivingKey $\TransmitPrivate$, the \viewingKey
$\ViewingKey = (\AuthPublic, \TransmitPrivate)$, and the \paymentAddress
$\PaymentAddress = (\AuthPublic, \TransmitPublic)$ are derived from the
\spendingKey $\AuthPrivate$.
$\PaymentAddress = (\AuthPublic, \TransmitPublic)$ are derived from
$\AuthPrivate$, as described in \crossref{keycomponents}.

The following diagram depicts the relations between key components.
Arrows point from a component to any other component(s) that can be derived
