Harald Welte wanted + to see the communication between a GSM Mobile Station (or + what we call a cellphone) and the SIM. He was not able to + find an existing solution, or the existing ones had mayor + drawbacks that made using them very time consuming and slow. + The Atmel AT91SAM7 came to the rescue. This microcontroller + has hardware support for the ISO7816 T0/T1 Smart Card + specification. Using this hardware with the clock coming from + the normal connection we are able to read bytes coming from + and going to the SIM. + The next step in the project was taken by Kevin Redon + that started to modify an existing AT91SAM7 design, started + to use the Free Software KiCAD CAD Software. In 2011 the project + went from having Schematics to having routed circuits, prototypes + and the final product. The first production run was in August.</para> + </section> + <section id="intro_picture"> <title>Overview</title> - <para></para> + <para>The setup of SIMtrace consists out of a Hardware and a + Software part. The SIM card needs to be put into the SIMtrace + Hardware, the flex cable needs to be connected to the SIMtrace + Hardware and the SIM end needs to be placed in the SIM socket + of the phone. The SIMtrace hardware can be seen as a USB device + from the host, the SIMtrace software will try to find this device + and claim it. The SIMtrace software will receive packets from the + SIMtrace hardware and can forward them using the GSMTAP protocol + to the IANA assigned GSMTAP port (4729). A modified version of Wireshark + can be used to analyze the data.</para> + + <figure><title>Schematic Overview</title> + <mediaobject> + <imageobject> + <imagedata fileref="images/setup_overview.png" width="6cm"/> + </imageobject> + <textobject><phrase>SIMtrace being connected</phrase></textobject> + </mediaobject> + </figure> </section> </chapter> |
