Extractors: Low Entropy Requirements Colliding With Non-Malleability. (arXiv:2111.04157v2 [cs.IT] UPDATED)

The known constructions of negligible error (non-malleable) two-source
extractors can be broadly classified in three categories:

(1) Constructions where one source has min-entropy rate about $1/2$, the
other source can have small min-entropy rate, but the extractor doesn't
guarantee non-malleability.

(2) Constructions where one source is uniform, and the other can have small
min-entropy rate, and the extractor guarantees non-malleability when the
uniform source is tampered.

(3) Constructions where both sources have entropy rate very close to $1$ and
the …

classified entropy error guarantee low non rate requirements
