Hands on PAL RE: microprobing and more


Programmable Array Logic (PAL) chips are early programmable logic chips with relatively easy to study architecture and security mechanisms. In this hands-on workshop we'll use several techniques including micro-probing and electrically "brute forcing" to extract their firmware and/or logically equivalent firmware.

What to expect?

  • Students will defeat die level security circuitry by reconnecting blown security fuses under a microscope using very precise needles
  • Students will learn to use specialized PAL hardware and software tools to apply electrical test signals to the PALs and create equivalent programming files
  • For more information see this link

This workshop is limited to 12 people / batch and we'll run the workshop twice during the event (90 min / session). To secure your seat, please fill in this form. Only conference attendees can participate in the workshop.
