I’ve been impressed from the prices that some companies take for their  
products named “Data diode”.

> A unidirectional network (also referred to as a unidirectional gateway or data diode) is a network appliance or device that allows data to travel in only one direction. Data diodes can be found most commonly in high security environments, such as defense, where they serve as connections between two or more networks of differing security classifications. Given the rise of industrial IoT and digitization, this technology can now be found at the industrial control level for such facilities as nucle...

It seems a good project (just little out of topic) to implement in  
GNURadio.

I’ll post some flow graphs soon.
