DDK Use-Cases

The DDK is an open-source hardware and software toolchain designed with hardware reverse-engineering and security analysis in mind. This page provides an overview of the DDK's core features as well as a several use-cases. If you're interested in a more detailed description of what the DDK can be used for, please reffer to our WOOT 2013 paper.

Key Features

Low cost development and attack-platform

  • ARM MCU + FPGA + FTDI USB UART
  • Easy access to I/O
    • RJ-45 expansion jacks with +5V and GND
    • Standard headers for breakout
    • Buffered, protected 3V/5V tolerant I/O
    • ARM JTAG and FPGA JTAG
  • 5V USB-Bus-powered device, optionally over a USB Y-Cable

LPC17 family Cortex-M3 ARM

  • Up to three bi-directional UARTs to the FPGA
  • Dedicated UART interface to the PC via FTDI USB
    • Provides Command Line Interface for user interaction
    • Non-Interactive mode for transferring data
    • On-chip boot-loader for USB upgradable firmware
  • Control and configuration of all onboard- and FPGA-peripherals

FPGA

  • USB upgradable bit-stream
  • 48 GPIO, eight channels with six bi-directional lines
  • Wishbone compatible internal bus
  • Extensive expansion capabilities

Example Use-cases
