WebRecently nonlinear feedback shift registers (NFSRs) have frequently been used as building blocks for designing stream ciphers. Let NFSR ( g ) be an m -stage NFSR with characteristic function $${g=x_{0}\oplus g_{1}(x_{1},\cdots ,x_{m-1})\oplus x_{m}}$$ .Up to now there has been no known method to determine whether the family of output sequences of the … Web26 de dez. de 2024 · Jiang Y P and Lin D D, On affine sub-families of Grain-like structures, Designs Codes and Cryptography, 2024, 82(3): 531–542.

On affine sub-families of the NFSR in Grain SpringerLink

Web1 de ago. de 2024 · The cascade connection of NFSRs, known as an important architecture, has been adopted in Grain family of stream ciphers. In this paper, a new sufficient condition under which an NFSR cannot be decomposed into the cascade connection of two smaller NFSRs is presented, which is easy to be verified from the … Web12 de jun. de 2024 · On the Affine Sub-Families of Quadratic NFSRs Abstract: Grain-128 is a hardware oriented stream cipher based on the cascade connection of a 128-bit linear feedback shift register into a 128-bit quadratic nonlinear feedback shift register (NFSR). port registration for import

A New Method for Finding Affine Sub-Families of NFSR Sequences
