Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Fourier analysis on finite abelian groups and the uncertainty principles
有限阿贝尔群 傅里叶分析 不确定性原理
2023/4/18
Let G be a finite abelian group. If f: G → C is a nonzero function with Fourier transform f , the Donoho-Stark uncertainty principle states that|supp(f)||supp(f )|≥|G|. The purpose of this talk is two...

Faster Homomorphic Discrete Fourier Transforms and Improved FHE Bootstrapping
Discrete Fourier Transform Homomorphic Encryption Bootstrapping
2018/11/12
In this work, we propose a faster homomorphic linear transform algorithm for structured matrices such as the discrete Fourier transform (DFT) and linear transformations in bootstrapping.

Constructing low-weight dth-order correlation-immune Boolean functions through the Fourier-Hadamard transform
Correlation-immune Fourier-Hadamard transform Low Hamming weight
2018/1/27
The correlation immunity of Boolean functions is a property related to cryptography, to error correcting codes, to orthogonal arrays (in combinatorics, which was also a domain of interest of S. Golomb...
FOURIER DOMAIN ITERATIVE APPROACH TO OPTICAL SECTIONING OF 3D TRANSLUCENT OBJECTS FOR OPHTHALMOLOGY PURPOSES
Sectioning 3D Deconvolution Convolution Iterative Regularization Method
2017/6/19
In this paper we deal with the problem of optical sectioning. This is a post processing step while investigating of 3D translucent medical objects based on rapid refocusing of the imaging system by th...
We present a methodology to evaluate a Discrete Fourier Transform (DFT) on data which has been encrypted using a Somewhat Homomorphic Encryption (SHE) scheme, which is over 200 times faster than other...
Finding Significant Fourier Coefficients: Clarifications, Simplifications, Applications and Limitations
Significant Fourier transform Goldreich-Levin algorithm Kushilevitz-Mansour algorithm
2016/7/13
Ideas from Fourier analysis have been used in cryptography for three decades. Akavia, Goldwasser
and Safra unified some of these ideas to give a complete algorithm that finds significant
Fourier coe...
The Fourier Entropy-Influence conjecture holds for a log-density 1 class of cryptographic Boolean functions
Boolean functions Fourier and Walsh-Hadamard transforms entropy
2016/1/26
We consider the Fourier Entropy-Influence (FEI) conjecture in
the context of cryptographic Boolean functions. We show that the FEI conjecture
is true for the functions satisfying the strict avalanch...
