\item Initialization
\begin{itemize}
\item Pick prime P s.t. $P = 2q + 1$ (sophie germaine prime)
\item Find a generator $g$ of a subgroup of $Z_p^*$ of
size order q
(half of primes fill this requirement)
\item $k' = g^{rf(0)} mod p$ where $r \in_R Z_p^*$
\item Share distribution: (t,n)
\\ $u_i \leftarrow (i, f(i))$
