\subsubsection{Authentication Center}
The \gls{ac} is the network component responsible for authenticating mobile subscribers.
-This authentication is not only done once when the subscriber connects to the network, but rather on many occasions \eg the start of a call or other significant events to avoid misuse by a third party.
-
+It is a part of the \gls{hlr} and the only place, apart form the customer's \gls{sim} card where the secret key \gls{ki} is stored.
+The authentication is not only done once when the subscriber connects to the network, but rather on many occasions \eg the start of a call or other significant events to avoid misuse by a third party.
+This authentication routine is a key based challenge-response procedure outlined in Figure \ref{fig:authentication}.
+The steps of the procedure can be summarized as follows:
+\begin{enumerate}
+ \item User connects to the network or triggers an event that needs authentication at the \gls{msc}.
+
+ In the first case the \gls{imsi} is part of the authentication request and the \gls{ac} starts with searching for the corresponding \gls{ki} and authentication algorithm A3.
+ An authentication triplet is build using \gls{ki} which consists of the components:
+ \begin{itemize}
+ \item RAND: a 128 bit random number.
+ \item SRES: a 32 bit number called signed response, which is generated by A3 with \gls{ki} and RAND as inputs.
+ \item Kc: the ciphering key that is used to cypher the data during transmission.
+ It is also generated with \gls{ki} and RAND.
+ \end{itemize}
+ To save signalling bandwidth, usually more than one authentication triplet is generated and returned to the \gls{msc} by the \gls{ac}.
+ It should be noted that, since a separate cyphering key is used, the secret key never leaves the \gls{ac}.
+
+ In the second case, either a previously generated authentication triplet is used, or new authentication triplets are requested.
+ \item RAND is transmitted to the \gls{ms} by the \gls{msc} where the signed response SRES* is created by the \gls{sim} card using A3, \gls{ki} and RAND.
+
+ \item An authentication response containing SRES* is sent back to the \gls{msc}.
+
+ \item If SRES and SRES* are the same, the subscriber is authenticated.
+\end{enumerate}
+
+Remarkable properties of this procedure are that by using a cyphering key that is generated by a random number and a secret key, the secret key itself never leaves the \gls{ac}.
+Apart from that the use of a random number prevents replay attacks on SRES.
+It should also be noted that this way of authenticating only works for authenticating the subscriber to the network.
+It is a one way authentication.
+The subscriber needs to trust the network.
+This is a design flaw that IMSI-Catchers use to lure \gls{ms} into their fake network.
+In \gls{umts} networks that flaw was fixed and the authentication procedure was made mutual.

The two subsystems above are necessary for the correct operation of a \gls{gsm} network.
