\begin{frame}{SIM card software}
\begin{itemize}
\item Every Smart Card has a Card Operating System (COS)
\item Cards without COS are simple memory cards (like I2C eeprom), insufficinet for SIM
\item Cards without COS are simple memory cards (like I2C EEPROM), insufficient for SIM
\item Card OS for Crypto Smart Cards (banking, access control) often publicly known
\item SIM Card OS are rarely known / publicly documented or even named
\item Example: ARM not only offers SIM card CPU core designs, but also OS (Kigen OS)
\item SIM Card OS is {\em implementtaion detail}, almost everything relevant is standardized
