Ich kennne mich überhaupt nicht aus mit latex und habe folgendes Problem:
\begin{aufgabe}{RSA}\vspace{-1cm}
For RSA the following parameters are know: $p=7, q=11$
\begin{enumerate}
\item Can the public key c be equal to 16?
\end{enumerate}
\begin{loesung}{Solution 1.}\vspace{-1cm}
\begin{enumerate}
\item In RSA the public key c has to be choosen such that it is prime relative to \\
\Phi(pq)=(p-1)(q-1).
So 16 has to be prime relative to $(7-1)*(11-1)=60$. This is not
the case because 16 and 60 have common divisors and therefore $c=16$ is not valid
\end{loesung}
\end{aufgabe}
