Hello,
I want to generate my own private key with dice and/or other very entropic phenomenon. But how can I calculate if my data have a good entropy ? I mean if I throw dice in a certain way too much time maybe my outcome will not be trully random, maybe my dice is not a very good dice and have imperfection etc.
So can I just throw it 300+ and if I don't have 0.166666% each result (1,2,3,4,5,6) it's not good ?
Also I want to write my own series of dice result just to compare how deficient is my brain when I try to generate true randomness.
Thanks
Try using the an open source program called
ent. Here are the results for rolling a die six times with the result vector of <666666>.
% echo -n "666666" | ./entEntropy = 0.000000 bits per byte.
Optimum compression would reduce the size of this 6 byte file by 100 percent.
Chi square distribution for 6 samples is 1530.00, and randomly would exceed this value less than 0.01 percent of the times.
Arithmetic mean value of data bytes is 54.0000 (127.5 = random). Monte Carlo value for Pi is 4.000000000 (error 27.32 percent). Serial correlation coefficient is undefined (all values equal!).
