Mathematical and computer modelling. Series: Technical sciences| Summary: | In this paper, one of the important elements of generator of stream ciphers — the nonlinear feedback shift registers (NLFSR) are considered. NLFSR with nonlinearity of random order are considered. The amount of different forming polynomials that can be used for NLFSR are studied. The result — calculated equations for determination of the number of NLFSR of random and maximal order (for a given size of the register) are showed. |
