Fibersystem Data Diode Middleware (DDMW)

NEW - Software Solution for transferring Data over Data Diodes in a controlled Manner

The primary problem with uni-directional ethernet data links is that no acknowledge information from a receiving system can be transferred back to the sender, so the sender has no way of knowing if the data it sent has been received. The workaround for this issue is to send and receive data in a controlled manner to avoid data loss.

The Data Diode Middleware (DDMW) is a software solution for transferring data over data diodes in such a controlled manner. It consist of a sender node and a receiver node which communicate through a uni-directional ethernet Data Diode.

DDMW supports three kinds of transfer types; messages and streams and UDP. Messages are any type of data with a finite and predefined length, like files and command instructions. Streams are data which either do not have an end or which does not have a predetermined length, such as an audio or video stream.

DDMW Features
  • Easy-to-use integration interface
  • Administrative role separation
  • Separate frontend/external and backend/internal systems
  • Full unidirectional system separation
  • Uncomplicated interface for SCADA application integrations
  • High-assurance separation of security domains
  • Separated role interfaces
  • Separated administrator role permissions
  • Hardware enforced unidirectionalness (With Fibersystem Data Diodes)
  • Transaction logs for traceability
