VIA C3 Random Number Generator Reviewed
An anonymous reader writes "VIA has added a hardware
random number generator to its Nehemiah C3 CPU. I found a recent review
of its security. Interesting how it's done at the instruction level as opposed to
the chipset level used by the i810 RNG (also reviewed there)."
No. Generally the idea of devices is just to amplify thermal noise. Thermal noise is produced at the microscopic level with atoms bouncing into each other. There's no way to predict that... unless you tap directly into the generator (in which case it's simpler to just get the data on the computer before it's encrypted).

Actually, I've heard of some experiment where people were asked to fake a "coin tossing session" and write down the results. Generally, you could tell it's fake because when "generating random numbers" people tend not to repeat sequences.

would be to use radioactive decay to generate random numbers. Very easy to implement using existeng technology, one of the few things that is completely random, and it's infinitely scalable to boot. A system I envision would simply moniter a radioactive sample for 1000 milli or micro seconds. Every sample time, it would record the number of fission events and if even, turn a bit on, if odd, turn the bit off. Then withing the space of a second you have a 1000 bit-long number that is COMPLETELY random.
With this system perhaps it's possible to emulate the electric fields that generate the random number. Admittedly, with any complexity at all (as in a chip) this becomes impractical to do, but hey, why go for almost random when you can have truly random?
I remmeber going to the university science library when I was 14 to try to find out how to write a program to generate random numbers...found a big yellow book about pseudo-random number generators and thought, no, I want a real random number generator...of course I opened the book and discovered that it is impossible inside a deterministic system...you have to stick an antenna into an external universe...then I thought where the fuck did the universe get noise? Why isn't the universe one big symmetric crystal?
Now I sit here looking at a 2 billion year-old hypernova and no one here can answer this question (There are at least 5 cosmoligists within spitting distance of me right now)...
