A low-cost, DIY data diode for ICS

DYODE : Do Your Own Diode

A DIY, low-cost data diode for ICS This project aims at creating a working data diode for a fraction of the price of the commercial ones.

This project includes two versions of DYODE :

• DYODE full : a 19" rack-sized data diode

• DYODE light : a very compact and ultra low-cost version with performance limitations

For detailed information, including steps to make your own, take a look at the wiki. You may also take a look at the public talks done on this project.

Hardware

The DYODE project is composed of 3 main parts:

• An INPUT counter
• A unidirectional, light-based data transfer mechanism
• An OUTPUT counter

The full version relies on optical-copper converters to transmit data, while the light version uses an optocoupler.

Hardware for DYODE light is open-source: PCB Gerber files are provided, as well as .stl files to 3D print the case.

Software

DYODE is an open-source project developed in Python.

Features

• Modbus data transfer
• File transfer (DYODE full only)
• Screen sharing (DYODE full only)
