Pseudorandom Generators from Regular One-way Functions: New Constructions with Improved Parameters
Foundations Pseudorandom Generators One-way Functions Randomized Iterate
2016/1/23
We revisit the problem of basing pseudorandom generators on regular one-way functions, and present the following constructions.
On the impossibility of efficiently combining collision resistant hash functions
resistant hash functions efficiently combining
2015/8/5
Let H1, H2 be two hash functions. We wish to construct a new hash function H that is collision resistant if at least one of H1 or H2 is collision resistant. Concatenating the output of H1 and H2 clear...
Homomorphic Signatures for Polynomial Functions
Polynomial Functions Homomorphic Signatures
2015/8/5
We construct the first homomorphic signature scheme that is capable of evaluating multivariate polynomials on signed data. Given the public key and a signed data set, there is an efficient algorithm t...
Algebraic pseudorandom functions with improved efficiency from the augmented cascade
improved efficiency pseudorandom functions
2015/8/5
We construct an algebraic pseudorandom function (PRF) that is more efficient than the classic Naor-Reingold algebraic PRF. Our PRF is the result of adapting the cascade construction, which is the basi...
Constrained Pseudorandom Functions and Their Applications
Their Applications Pseudorandom Functions
2015/8/5
We put forward a new notion of pseudorandom functions (PRFs) we call Constrained PRFs. In a standard PRF there is a master key k that enables one to evaluate the function at all points in the domain o...

As CMOS technology scaling is fast approaching its fundamental limits, several new nano-electronic devices have been proposed as possible alternatives to MOSFETs. Research on emerging devices mainly f...
A dual-layer optical disk comprised of a read-only layer and a phase-change layer was designed to perform the read-only and erasable dual-functionality in an optical disk. With the properly designed d...
Abstract: We use simple analytic considerations and a Monte Carlo calculation of nucleons in a box to argue that the use of Jastrow functions as short-range correlators in the commonly employed two-bo...
