Lowen and I just received word of acceptance of our recent work to ISIT.  This papers asks whether you can build a universal fuzzy extractor for all high fuzzy min-entropy distributions.  That is, can we have one construction that always just works.  Unfortunately, the answer is negative.  It is possible to artificially construct families of distributions that are impossible to simultaneously secure.  This paper shares a lot of techniques with prior work of myself, Reyzin, and Smith.  Excited to talk about these techniques more with the information theory community!
