How to generate a random number for a private key:
Step 1) aquire a Geiger counter tube (G-M tube)
Step2) acquire americium-241
Mount these next to each other.
The americium occasionally emits a gamma ray in a random direction.
Sometimes that direction is towards the G-M tube.
The timing is random.
It can't be spied on because it's vector/directional.
This is how I will be generating my private keys from now on.
Nature’s blinded randomness.
americium, for the uninformed, is present in cheap, non-optical type smoke detectors. the little grain of radiactive crap is inside a little lead case and has a hole in one direction, and a sensor goes directly in front of it, similar to a geiger counter, and when there is smoke in the air, the average rate of emission is reduced and it triggers the alarm.
probably you could adapt the radio-smoke-sensors to just feed a trigger that is read by your CSPRNG to reseed it, would just need a simple USB adapter that takes the signal and then sends some utility USB protocol message.
thank you
It’s been done - there’s a patent on it since the mid 90’s. I worked for the company that held the patent and designed an encryption product around it for healthcare.
