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 …

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 …

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 …

In this paper, a family of new de Bruijn sequences is proposed through the construction of
maximum-length nonlinear feedback shift registers (NFSRs). Let be a positive integer and …

Nonlinear feedback shift registers (NFSRs) have been used as the main building blocks in
many stream ciphers and convolutional decoders. The linearization of NFSRs is to find their …

We explain the origins of Boolean feedback functions of nonlinear feedback shift registers
(NLFSRs) of fixed order n generating de Bruijn binary sequences. They all come into …

Sequences generated by maximum-period nonlinear feedback shift registers are known as
de Bruijn sequences. The problem of generating de Bruijn sequences has received …

Nonlinear feedback shift registers (NLFSRs) are used to construct pseudorandom
generators for stream ciphers. Their theory is not so complete as that of linear feedback shift …

In lightweight block cipher design, generating permutation boxes (P-boxes) is critical to
security and efficiency. This paper introduces an innovative approach to P-box generation …

Non-linear feedback shift registers (NLFSRs) are a generalization of linear feedback shift
registers in which a current state is a non-linear function of the previous state. The interest in …
