Using Hadamard transform for cryptanalysis of pseudo-random generators in stream ciphers [PDF]

EAI Endorsed Transactions on Energy Web, 2020
In this work we discuss results obtained from an application of the Hadamard transform to cryptanalysis, andin particular, we determine the probability to decipher different pseudo-random number generators used ascomponents of stream ciphers.

The Improvement on the Performance of DMD Hadamard Transform Near-Infrared Spectrometer by Double Filter Strategy and a New Hadamard Mask

Micromachines, 2019
In the Hadamard transform (HT) near-infrared (NIR) spectrometer, there are defects that can create a nonuniform distribution of spectral energy, significantly influencing the absorbance of the whole spectrum, generating stray light, and making the signal-

The Cascading Haar Wavelet algorithm for computing the Walsh-Hadamard Transform [PDF]

, 2016
We propose a novel algorithm for computing the Walsh-Hadamard Transform (WHT) which consists entirely of Haar wavelet transforms. We prove that the algorithm, which we call the Cascading Haar Wavelet (CHW) algorithm, shares precisely the same serial ...

Some Cryptographic Properties of Functions Based on their 2q-Nega-Hadamard Transform [PDF]

International Journal of Mathematical, Engineering and Management Sciences
Negabent functions play a vital role in the field of cryptography and coding theory for designing secure cryptosystems. In this article, we investigate the various properties of 2q-nega-Hadamard transform (2q-NHT) of the functions from Z_q^n to Z_2q with

Computational ghost imaging with hybrid transforms by integrating Hadamard, discrete cosine, and Haar matrices [PDF]

A scenario of ghost imaging with hybrid transform approach is proposed by integrating Hadamard, discrete cosine, and Haar matrices. The measurement matrix is formed by the Kronecker product of the two different transform matrices.

Pauli decomposition via the fast Walsh-Hadamard transform

New Journal of Physics
The decomposition of a square matrix into a sum of Pauli strings is a classical pre-processing step required to realize many quantum algorithms. Such a decomposition requires significant computational resources for large matrices. We present an exact and
