HVOC -- Hacking Vehicle On-board Communications

  • This semester you will use a simulated SAE J1939 vehicle network to demonstrate methods to protect and attack messages sent between vehicle controllers.
  • You will use a virtual machine (VM) use as your lab bench.
  • The VM is for your individual use.
  • The VM is already configured for simulating CANBUS.
  • You will write or edit (small) python scripts:
    • sometimes to provide and/or validate security of your design.
    • sometimes to attack a security scheme provided by the instructor.
  • During the semester, you will see the techniques you learned applied to two proposals for international standards relevant to securing vehicle on-board communications used in agricultural equipment.

Login Before First Class

Please log into your VM before the first day of class.

  • You will receive an invitation to your VM via email
  • Use these instructions to get started.
    • Note: you will install an X-window client.

Overview/Lab Inspiration

Our (Truck, Bus, Ag, i.e., SAE J1939) lab environment was inspired by the automotive simulator, "ICSim" (IC means "instrument cluster"). The video link below shows setting up and using ICSim.
