btw I have RPI3 too, thanks for mentioning. it would be fun project to figure out can we reach true source on that chip. but 1,5Mpbs? highly suspect. they don't have space nor clock speed to sample so many true events on that tiny chip

Here is the problem: most of these stats are not what they pretend to be (unless exact circuit / spec is published). Look at low level details of building say avalanche noise source: http://holdenc.altervista.org/avala

The key property for crypto randomness here is that these high energy particle events (be that cosmic rays, background radiation, etc) are not just random, but independent from thermal noise. They are few and far between but they affect eac

worth mentioning (that sort of main premise of the article that gets a little bit unnoticed in all the methodology discussion): all existing HWRNG are relatively low bandwidth - because they are bound by physical process, rather then endles

Do you have any references of existing code or research that deals with correlation issues? We considered few home grown ideas (like measuring correlation level in each sample and then compacting a sample by that % before quantizing) but al

you are completely correct - as I mentioned in the end this would be easier extractor: "Want to relax IID assumptions and avoid careful setup of a non-correlated quantizer? Easy — use any good universal hash function. The only new requ

my motivation from a while back was it would be so useful to have something that you can dump few megs of independent entropy into your /dev/urandom right before generating BTC/ssh keys. TrueRNG stick is also good, but just 4

you are quite correct about this - "lens closed" mode has least amount of entropy by our measure. However its clearly proportional to intensity of light hitting the sensor (and beside natural photon variance of light itself, the s
