We propose a simple and efficient deterministic extractor for the (hyper)elliptic curve C, defined over Fq2 , where q is some power of an odd prime. Our extractor, for a given point P on C, outputs the first Fq-coefficient of the abscissa of the point P . We show that if a point P is chosen uniformly at random in C, the element extracted from the point P is indistinguishable from a uniformly ra...

A Fuzzy Extractor (Dodis et al., Eurocrypt 2004) is a two-step protocol that turns a noisy secret into a uniformly distributed key R. To eliminate noise, the generation procedure takes as input an enrollment value ω and outputsR and a helper string P that enables further reproduction ofR from some close reading ω′. Boyen highlighted the need for reusable fuzzy extractors (CCS 2004) that remain ...

Hannah Arendt identifies the onset of genocide under the Nazi regime with the declaration that ‘the German people not only were unwilling to have any Jews in Germany, but wished to make the entire Jewish people disappear from the face of the earth.’1 Arendt famously, and unpopularly, contended that the crime was a crime against humanity, perpetrated upon the body of the Jewish people.2 Eichmann...

It was only a few decades ago that incision and suction were recommended snakebite first aid. However, concerns arose about injuries and infections caused when laypersons made incisions across fang marks and applied mouth suction. Meanwhile, several snakebite suction devices (eg, Cutter’s Snakebite Kit, Venom Ex) were evaluated, and it was determined that they were neither safe nor effective.1 ...
