The Ggm Construction Does Not Yield Correlation Intractable Function Ensembles Introduction and Statement of Our Result

چکیده
We consider the function ensembles emerging from the construction of Goldreich, Goldwasser and Micali (GGM), when applied to an arbitrary pseudoramdon generator. We show that, in general, such functions fail to yield correlation intractable ensembles. Speciically, it may happen that, given a description of such a function, one can easily nd an input that is mapped to zero under this function.

The GGM Construction Does NOT Yield Correlation Intractable Function Ensembles
We consider the function ensembles emerging from the construction of Goldreich, Goldwasser and Micali (GGM), when applied to an arbitrary pseudoramdon generator. We show that, in general, such functions fail to yield correlation intractable ensembles. Specifically, it may happen that, given a description of such a function, one can easily find an input that is mapped to zero under this function.
متن کاملA Relationship between One-Wayness and Correlation Intractability
The notion of correlation intractability was introduced in an attempt to capture the “unpredictability” property of random oracles: It is assumed that if R is a random oracle then it is infeasible to find an input x such that the input-output pair (x,R(x)) has some desired property. It is desirable that a plausible construction of correlation intractable function ensembles will be provided sinc...
متن کاملOn the Social Construction of Overdiagnosis; Comment on “Medicalisation and Overdiagnosis: What Society Does to Medicine”
In an interesting article Wieteke van Dijk and colleagues argue that societal developments and values influence the practice of medicine, and thus can result in both medicalisation and overdiagnosis. They provide a convincing argument that overdiagnosis emerges in a social context and that it has socially constructed implications. However, they fail to show that overdiagnosis per se is socially...
متن کاملA Case Report of Glucose-Galactose Malabsorption in Iranian Child
Introduction Glucose-Galactose Malabsorption (GGM) is an autosomal recessive and rare disorder of intestinal transport of glucose and sodium-glucose cotransporter type (SGLT1). Case Report Our patient is a 32-day-old boy who was examined for severe diarrhea and acidosis and was treated with GGMdiagnosis. A number of laboratory tests were performed on this patient as well as positive test for r...
متن کاملLong term effects of kidney donation on blood pressure and kidney function of donors
Introduction: Kidney transplantation from a live donor has many advantages, but the donor should undergo a major surgery and accept potential morbidity and mortality. In this study, we evaluated the long term effects of nephrectomy on renal function and blood pressure of kidney donors. Methods: In this cross-sectional study, we assessed 195 kidney donors. The controls were 100 healthy individu...
