Board modification

There were several side-channel analysis and fault injection tasks which required board modification. Organizers provided board design to ease modification.

Here is what we did:

• Removed capacitors C17, C16 and C7
• Removed usb-to-serial chip CH340G
• Cut track at JP4;
• Added shunt resistor 10 Ohm before VCC pin to measure current
• Added some filtering before shunt resistore

For hardware tasks we used:

• Chipwhisperer. For SCA and FI
• DSCope. Oscilloscope
• Saleae Logic. Logic analyzer
• Arduino with 2 CAN-Bus shields. For CAN tasks and additionally as trigger for SCA tasks
• BeagleBone Black. For Key Fob task
