Constructing and Solving the System of Linear Equations Produced From LFSR Generators

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
  Linear Feedback Shift Register (LFSR) systems are used  widely in stream cipher systems field. Any system of LFSR's which wauldn't be attacked must first construct the system of linear equations of the LFSR unit. In this paper methods are developed

Partial Sums Generation Architecture for Successive Cancellation Decoding of Polar Codes

, 2013
Polar codes are a new family of error correction codes for which efficient hardware architectures have to be defined for the encoder and the decoder. Polar codes are decoded using the successive cancellation decoding algorithm that includes partial sums ...

Best Known Fast Correlation Attack on SNOW 3G Based on a New Insight

IET Information Security, Volume 2025, Issue 1, 2025.
The well‐known SNOW 3G stream cipher serves as the core of 3GPP confidentiality and integrity algorithms UEA 2 and UIA2 for universal mobile telecommunications system (UMTS) and long term evolution (LTE) networks. Recently, Gong and Zhang gave two linear approximations of SNOW 3G with correlation 2−20.48, and then proposed a fast correlation attack on ...

LRH‐1/NR5A2 targets mitochondrial dynamics to reprogram type 1 diabetes macrophages and dendritic cells into an immune tolerance phenotype

Clinical and Translational Medicine, Volume 14, Issue 12, December 2024.
LRH‐1/NR5A2 activation in inflammatory cells of individuals with type 1 diabetes (T1D) reduces pro‐inflammatory cell surface markers and cytokine release. LRH‐1/NR5A2 promotes a mitohormesis‐induced immuno‐resistant phenotype to pro‐inflammatory macrophages.

Optimized Method for Generating and Acquiring GPS Gold Codes

International Journal of Antennas and Propagation, 2015
We propose a simpler and faster Gold codes generator, which can be efficiently initialized to any desired code, with a minimum delay. Its principle consists of generating only one sequence (code number 1) from which we can produce all the other different

Multilevel Permutation with Different Block Size/ Stream Cipher Image Encryption [PDF]

Iraqi Journal for Electrical and Electronic Engineering, 2015
In this work, a new image encryption method using a combined multilevel permutation with stream cipher is proposed. In the permutation algorithm, image is divided into blocks in each level and its blocks are rearranged by using pseudorandom permutation

Note on Marsaglia's Xorshift Random Number Generators [PDF]

Marsaglia (2003) has described a class of Xorshift random number generators (RNGs) with periods 2^n - 1 for n = 32, 64, etc. We show that the sequences generated by these RNGs are identical to the sequences generated by certain linear feedback shift ...

Global Linear Complexity Analysis of Filter Keystream Generators

, 1997
An efficient algorithm for computing lower bounds on the global linear complexity of nonlinearly filtered PN-sequences is presented. The technique here developed is based exclusively on the realization of bit wise logic operations, which makes it ...
