In this paper, a novel way is proposed to investigate the transformation between Galois
nonlinear feedback shift registers (NLFSRs) and Fibonacci NLFSRs. First, the Galois …

The demand for more efficient ciphers is a likely to sharpen with new generation of products
and applications. Previous cipher designs typically focused on optimizing only one of the …

Nonlinear feedback shift registers (NFSRs) are the main components of stream ciphers and
convolutional decoders. Recent years have seen an increase in the requirement for …

Non-Linear Feedback Shift Registers (NLFSRs) are a generalization of Linear Feedback
Shift Registers (LFSRs) in which a current state is a nonlinear function of the previous state …

A method for constructing n-stage Galois NLFSRs with period 2 n-1 from n-stage maximum
length LFSRs is presented. Nonlinearity is introduced into state cycles by adding a nonlinear …

Grain is one of three hardware-oriented finalists of the eSTREAM Project. A nonlinear
feedback shift register (NFSR) in Grain-like structure is a cascade connection of a linear …

Energy optimization is an important design aspect of lightweight cryptography. Since low
energy ciphers drain less battery, they are invaluable components of devices that operate on …

Driven stable nonlinear feedback shift registers (NFSRs) with inputs are not only able to limit
error propagations in convolutional decoders, but also helpful to analyze the period …

Nonlinear feedback shift registers (NFSRs) have been used in many recent stream ciphers.
They are generally classified into Fibonacci NFSRs and Galois NFSRs according to their …

With the combined call for increased network throughput and security comes the need for
high-bandwidth, unconditionally secure systems. Through the combination of true random …
