Facts I looked up to understand this comment: * Bias in a bit-stream means any deviation from IID Bernoulli trials with p=0.5 * Von Neumann whitening addresses the IID Bernoulli case for p!=0.5 by looking at bit pairs. It takes the first bit when they differ, and no bits when they match. This works because (1,0) and (0,1) both occur with equal probability p(1-p). * NIST wrote a remarkably accessible document [1] [1] https://csrc.nist.gov/csrc/media/publications/sp/800-90b/draft/documents/draft-sp800-90b.pdf https://csrc.nist.gov/csrc/media/publications/sp/800-90b/dra...
