$\PRF{x}{}$ is a \pseudoRandomFunction keyed by $x$. \changed{Four} \emph{independent}
$\PRF{x}{}$ are needed in our protocol:
\begin{tabular}{@{\hskip 2em}l@{\;}l@{\;}l@{\;}l}
$\PRFaddr{} $&$\typecolon\; \bitseq{\AuthPrivateLength} $&$\times\; \range{0}{255} $&$\rightarrow \PRFOutput $\\
$\PRFnf{} $&$\typecolon\; \bitseq{\AuthPrivateLength} $&$\times\; \PRFOutput $&$\rightarrow \PRFOutput $\\
$\PRFpk{} $&$\typecolon\; \bitseq{\AuthPrivateLength} $&$\times\; \hSigType $&$\rightarrow \PRFOutput $\\
$\PRFrho{} $&$\typecolon\; \bitseq{\NoteAddressPreRandLength} $&$\times\; \hSigType $&$\rightarrow \PRFOutput $

These are used in \crossref{jsstatement}; $\PRFaddr{}$ is also used to
