It is true Random Generator :P. I guess someone can predict the output if the algorithm inside the chip can be hack.

@arefatx No it cannot, that's the nature of a TRNG in comparison to a PRNG.

To verify randomness, couldn't you roll the dice 100,000 times and calculate the actually probability of getting a 3 (for example), that is, you should have gotten 33,333 3's. Or calculated how many landed on even; 500,000.

Yes, that's a simple equi-distribution test with probability classes. However that by itself is not a sufficient criteria for good randomness, the test siute does considerably more than that.

impressive work trng at an impressive speed ;-)

"There's not even a thing like randomness ;-)"

what suite did you use to test the entropy ?

[linuxgeek81]

Well it's gotten slower since I'm using SHA160 to straighten out the entropy ;) I had two test suites, one from NIST and another one...

Did you place the device inside a faraday cage enclosure to remove any coherent magnetic fields that can interfere with the noise signal? What can you do about ELF waves or the inconsistencies in ground?

eine gute idee. rauschen von z.b einem widerstand zu verstärken sollte doch auch echten zufall erzeugen, oder?

What are you using for the entropy feed?

[micolsdk]

hehe it doesn't look random, that was my thought as well :P

What's the purpose/goal with this noise generator you've made?
