OneRNG

posted December 2014

I like how people make an extreme effort to create "sure" source of random numbers.

OneRNG has released a new usb source. Everything is opensource (open hardware, open software), you can even create your own by following instructions on their websites.

OneRNG collects entropy from an avalanche diode circuit, and from a channel-hopping RF receiver. It even has a “tinfoil hat” to prevent RF interference — you can remove the hat in order to visually verify the components being used.

Now I'm wondering who is using that and for what

Well done! You've reached the end of my post. Now you can leave me a comment :)
