Scrambling and De-Scrambling Implementation Using Linear Feedback Shift Register Method on FPGA
IJAIT (International Journal of Applied Information Technology), 2017 Digital broadband communications require a fast, functional and efficient system. In a digital communication system, a long sequence of bits '0' or '1' will inherits the loss of bit synchronization, and hence it can cause the false detection on the ...

Enhancing Medical Image Security Leveraging Quantum Key Distribution
IET Quantum Communication, Volume 7, Issue 1, January/December 2026.This paper proposes QKD assisted quantum encryption for medical images. BB84 protocol is utilised to generate a secure shared key, which is further enhanced using Henon maps. The logistic map whose parameters are derived from the shared key is employed to generate the permutation sequence for pixel values.

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.In this paper, a new method for multistage digital sigma–delta modulators (DDSMs) is presented to increase the output sequence period and reduce fractional spurs. The output of a DDSM is always a periodic signal when the input is constant. A hybrid DDSM is premiere to its conventional counterpart for having a potential speed, by the choice of its ...

On Sequence Lengths of Some Special External Exclusive OR Type LFSR Structures – Study and Analysis
The Journal of Engineering Research, 2014 The study of the length of pseudo-random binary sequences generated by Linear- Feedback Shift Registers (LFSRs) plays an important role in the design approaches of built-in selftest, cryptosystems, and other applications. However, certain LFSR structures

An LFSR-based address generator using optimized address partition for low power memory BIST
Journal of Measurement Science and Instrumentation, 2020 Power consumption in test mode is much higher than that in normal mode, which is prone to causing circuit damage and reducing the yield of chips. To reduce the power dissipation efficiently, a modified linear feedback shift register（LFSR） is designed to ...

Cellular Automata-Based Parallel Random Number Generators Using FPGAs
International Journal of Reconfigurable Computing, 2012 Cellular computing represents a new paradigm for implementing high-speed massively parallel machines. Cellular automata (CA), which consist of an array of locally connected processing elements, are a basic form of a cellular-based architecture.

On the decomposition of an NFSR into the cascade connection of an NFSR into an LFSR
Journal of Complexity, 2013 In this paper, we study the decomposition of an NFSR into a cascade connection of an NFSR into an LFSR which is a kind of concatenation of an NFSR and an LFSR. It is shown that this problem can be solved based on polynomial factorization in F"2[x], and a potential weakness of an NFSR that can be decomposed in such a way is further discussed.
