\begin{itemize}
\item Fields of Applications:
\begin{itemize}
\item Information Security: Hash function, Steganography, Stream cipher
\item Time Synchronization: GPS
\item Numerical simulations: Monte-Carlo algorithms
\item<-2> Simulation of Chaotic systems: Double pendulum, Protein dynamics
\item \ldots  
\end{itemize}
\item Practical requirements:
\begin{itemize}
\item Reproducibility: same seed $\leadsto$ same stream 
\item Successfull pass on PRNG batteries of tests
currently the NIST suite~\cite{Nist10}, and DieHARD~\cite{Marsaglia1996}
\item<-2> Should have chaotic properties if needed
\end{itemize}
