Questions on Private Key Generation

[funkenstein]

From a google search, I discovered hexadecimal dice too. Unfortunately, I can't find any to order in the UK.

But do they have the same probabilities for each side? I think only platonic solids have that property. An icosahedron would be fine, turning 16 to zero and discarding 17 to 20.

It is possible to make fair dice for any n number of sides (one solution is pencil shaped with n-polygon cross section), but platonic solids are definitely cooler

What is that?

Second try:



Those aren't mine, though .

I think this would take a ridiculous amount of time to generate a private key, plus the fact that rolling dice this way is going to both increase the chances of making an error as well as you getting impatient and just using "random" number from your head part of the way through the process

Obviously you didn't try it, did you? With 6 dice you only need 17 iterations of the loop "roll, write down", easily done in under 3 minutes (at 10 seconds per iteration, which is more than enough). No faulty/compromised RNGs, just pure entropy from the universe, no source code needed. You only have to take care of reading the dice always in the same order, eg. start at yellow and go clockwise.

this is why we are experimenting with simple home-made Quantum True RNG here (the thread is in Russian).
this RNG is cheap, simple and surprisingly stable, but with SBM-20 geiger counter it is slow, just 0.1-0.5 bits per second.
using new alpha-sensitive counter excited with Am247 source I hope we will have at least 10kbps soon.
