If you are super paranoid, you'll need to find a hardware random generator which you've built yourself --- and hopefully you are competent enough to actually build a real HWRNG, and not something which is sampling 60 Hz hum (or 50 Hz hum if you are in Europe :-), and mix that into the entropy pool as well.
What do you propose as a low cost solution? I've seen some interesting suggestions, such as having a small fish bowl or tube or tank, having air pumped into the bottom, and sampling the patterns of bubbles with some CV solution. Sounds geeky, would make for a nice decoration on one's table, but building it seems like quite a job.

- amalcon 13y agoSit a Geiger counter next to a jar of Brazil nuts, and time events? You would need a way of testing the Geiger counter, but that should be possible. Alternatively, buy one at surplus from a university laboratory. If they're any good, they would have already noticed it misbehaving.

- gngeal 13y agoHmm. Haven't thought of that. Comparatively simple, yet also compact at the same time. Thanks, nice!
