基于m-序列的本原σ-LFSR序列构造

四川大学学报. 自然科学版, 2009
σ-LFSR是一基于字的LFSR模型,它能够充分利用现代CPU的特点,具有结构简单、适合软件快速实现的特点.在实际应用中,本原σ-LFSR最有价值,因此它的构造具有重要意义.本文首先考察了基于字的本原LFSR的距离向量,得到了它的若干性质,给出了一个距离向量为本原LFSR的充要条件;然后对本原σ-LFSR的距离向量进行了研究,利用基判别定理给出了它的部分性质,并以此为基础得到了一个利用m-序列构造本原σ-LFSR序列的搜索算法.最后对搜索算法编程实现,得到了有限域F2～3上所有2级本原σ ...

FPGA Realization of a Novel Hyperchaos Augmented Image Encryption Algorithm

IET Computers &Digital Techniques, Volume 2026, Issue 1, 2026.
With the rapid growth of multimedia communication, protecting image data has become increasingly critical. This article proposes a novel 3‐stage hyperchaos‐based augmented image encryption technique (3SHAIET) that utilizes a three‐stage process with chaotic systems of increasing dimensionality (e.g., six‐dimensional [6D], 8D, and 9D) to enhance ...

A Novel Image Steganographic Method Based on Enhanced PIWT and Modified Optimal Pixel Adjustment Process

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel image steganographic method based on an enhanced Pyramid Integer Wavelet Transform (PIWT) combined with a Modified Optimal Pixel Adjustment Process (MOPAP). The PIWT enables integer‐to‐integer transformation, avoiding floating‐point computations and improving its suitability for efficient implementation.

Design a Third‐Order DDSM With Effective Random Dither in Fractional Frequency Synthesizers to Reduce Fractional Spurs

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 ...

A fast signature computation algorithm for LFSR and MISR

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2000
A multiple-input signature register (MISR) computation algorithm for fast signature simulation is proposed. Based on the table look-up linear compaction algorithm and the modularity property of a single-input signature register (SISR), some new accelerating schemes-partial-input look-up tables and flying state look-up tables-are developed to boost the ...
