Pseudorandom knapsacks and the sample complexity of LWE search-to-decision reductions

D Micciancio, P Mol - Annual cryptology conference, 2011 - Springer
We study the pseudorandomness of bounded knapsack functions over arbitrary finite
abelian groups. Previous works consider only specific families of finite abelian groups and 0 …

Batch binary edwards

DJ Bernstein - Annual International Cryptology Conference, 2009 - Springer
This paper sets new software speed records for high-security Diffie-Hellman computations,
specifically 251-bit elliptic-curve variable-base-point scalar multiplication. In one second of …

The hardness of LPN over any integer ring and field for PCG applications

H Liu, X Wang, K Yang, Y Yu - … International Conference on the Theory and …, 2024 - Springer
Learning parity with noise (LPN) has been widely studied and used in cryptography. It was
recently brought to new prosperity since Boyle et al.(CCS'18), putting LPN to a central role in …

BN Mohapatra, RK Mohapatra - 2017 Fourteenth International …, 2017 - ieeexplore.ieee.org
Currently, the FFT is used in different areas, starting from identification of frequency on
mechanical vibration to image enhancement. Real-time computation by interpret the …

Solving hidden number problem with one bit oracle and advice

A Akavia - Annual International Cryptology Conference, 2009 - Springer
Abstract In the Hidden Number Problem (HNP), the goal is to find a hidden number s, when
given p, g and access to an oracle that on query a returns the k most significant bits of …

Hardness of computing individual bits for one-way functions on elliptic curves

A Duc, D Jetchev - Advances in Cryptology–CRYPTO 2012: 32nd Annual …, 2012 - Springer
We prove that if one can predict any of the bits of the input to an elliptic curve based one-way
function over a finite field, then we can invert the function. In particular, our result implies that …

On Fourier analysis of sparse Boolean functions over certain Abelian groups

S Chakraborty, S Datta, P Dutta, A Ghosh… - arXiv preprint arXiv …, 2024 - arxiv.org
Given an Abelian group G, a Boolean-valued function f: G->{-1,+ 1}, is said to be s-sparse, if
it has at most s-many non-zero Fourier coefficients over the domain G. In a seminal paper …

The multivariate hidden number problem

SD Galbraith, B Shani - International Conference on Information Theoretic …, 2015 - Springer
This work extends the line of research on the hidden number problem. Motivated by studying
bit security in finite fields, we define the multivariate hidden number problem. Here, the …

Hardness amplification within NP against deterministic algorithms

P Gopalan, V Guruswami - Journal of Computer and System Sciences, 2011 - Elsevier
We study the average-case hardness of the class NP against algorithms in P. We prove that
there exists some constant μ> 0 such that if there is some language in NP for which no …
