The Von Neumann randomness extractor is explicitly mentioned in the randomness extractor page of Wikipedia, but strangely enough that page does not contain any reference to whitening the results of an entropy source.
Two intrinsically related questions:
- Is this Von Neumann randomness extractor indeed a form of whitening?
- Is whitening simply a part of randomness extractor, or is there another relation between whitening and randomness extraction?
Please only answer the second question if the terms are well defined enough to make a clear statement.
