  8. Plan • Redefining the project & Prevision • Methodology : how to • Bibliography Reverse Engineering on the IPod's USB protocol

  9. Redefiningtheproject • Our project, like we think it, can be named: “Reverse engineering on the Ipod USB protocol” Reverse Engineering on the IPod's USB protocol

  10. Our Goals • Reverse engineer the USB protocol of the Ipod and understand clearly the way its functions work • Be able to give commands to the Ipod • Understand the answers it gives Reverse Engineering on the IPod's USB protocol

  11. Our Goals • Develop an application able to use directly the discovered protocol • Find a good usage for the protocol • Develop the application itself Reverse Engineering on the IPod's USB protocol

  12. Gantt chart Reverse Engineering on the IPod's USB protocol

  13. How to do ? Using an UBS sniffer like USBSnoop (or SniffUSB) Interfacing between the application and the USB driver Catching every USB frame Using it to make some logs Reverse Engineering on the IPod's USB protocol

  14. How to do ? 06/11/08 Reverse Engineering on the IPod's USB protocol

  15. How to do ? Use a script written in python in order to purify logs It will remove all information we don’t need It will organize frames to be easier to understand 06/11/08 Reverse Engineering on the IPod's USB protocol

  16. How to do ? Understand the protocol Analyse the behaviour of the protocol while we use some functions of ITunes Highlight the important part of the communication Try to send some frames 06/11/08 Reverse Engineering on the IPod's USB protocol

  17. USB in a nutshell Universal Serial Bus (USB) is a serial bus standard to interface devices to a host computer In response of a data packect, we could have three basic responses : a ACK (data was successfully received) a NAK (data cannot be received at this time) a STALL (device has an error and never transfer data until some corrective action is perfomed) 06/11/08 Reverse Engineering on the IPod's USB protocol

  18. Bibliography Apple’s website & community Proprietary solutions Open Source community 06/11/08 Reverse Engineering on the IPod's USB protocol
