If the algorithms have precise knowledge of the probability distribution W that defines the noisy source is a sufficient condition for ...

Apr 1, 2020 · We ask: is fuzzy min-entropy sufficient to build fuzzy extractors? We provide two answers for different settings.

Fuzzy extractors (Dodis et al., Eurocrypt 2004) convert repeated noisy readings of a high-entropy secret into the same uniformly distributed key.

Fuzzy extractors are a method that allows biometric data to be used as inputs to standard cryptographic techniques, to enhance computer security.

Aug 23, 2016 · If only computational security is required, recent progress on program obfuscation gives evidence that fuzzy min-entropy is indeed sufficient.

In this paper, we show that fuzzy min-entropy is sufficient for information theoretically secure fuzzy extraction. For every source distribution ...

We propose two primitives: a fuzzy extractor reliably extracts nearly uniform randomness R from its input; the extraction is error-tolerant.

When are Continuous-Source Fuzzy Extractors Possible?

Reusable fuzzy extractors remain secure when multiple keys are produced from a single noisy secret (Boyen, CCS 2004). Boyen proved that any information- ...
