Re: [math-fun] true random generators

Gene, what does the entropy per bit tell us about the TRNG ? (If the answer is contained in what you wrote below, I'm too ignorant about RNG's to get it.) —Dan

I don't think accurate balancing is needed. The entropy per bit is S = -p log p - (1-p) log(1-p). So S(50,50) = 0.693, S(60,40) = 0.673 for a fractional loss of 3%. And S(75,25) = 0.562, a loss of 19%. That can be compensated by correspondingly increasing the key length.
