Model design for a reduced variant of a Trivium Type Stream Cipher
Journal of Computer Science and Technology, 2014 We analyze the family of stream ciphers N-viums: Trivium and Bivium. We present the Trivium algorithm and its variants. In particular, we study the NLFSRs used in these generators, their feedback functions and their combination.

IET Communications, Volume 20, Issue 1, January/December 2026.A communication model for collaborative and non‐collaborative scenarios is proposed, where the error correction code used by the transmitter is a cyclic code and the scrambler used is a synchronous scrambler. The contents of the dashed boxes are the tasks of the non‐collaborative receiver and our research targets the contents of the red boxes, that is,

IET Communications, Volume 20, Issue 1, January/December 2026.This paper addresses the blind identification of the feedback polynomial for a self‐synchronous scrambler applied to Reed–Solomon codes in non‐cooperative communications. We propose a novel fault‐tolerant method that leverages soft‐decision information to construct an average parity check confidence metric, derives its optimal detection threshold and ...

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 of Iterative MDS Matrices Based on MISTY Structure
IET Information Security, Volume 2026, Issue 1, 2026.The security of symmetric‐key ciphers critically depends on the diffusion efficiency of their linear components. Iterative maximum distance separable (MDS) matrices, as fundamental elements of diffusion layer, play a pivotal role in constructing secure cryptographic systems.

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 ...
