摘要：Paper is dedicated to a problem of the design techniques of Nonlinear Feedback Shift Register (NFSR) with nonlinear feedback Boolean function, which ensure the repeat cycle 2n for n-bit register and improve the sequences quality characteristics which have an impact on data protection efficiency. The combinatorial method for obtaining nonlinear feedback functions which ensure the repeat cycle 2n for n-bit shift register has been worked out. It has been proved that proposed method allowed to increase the number of obtained feedback nonlinear function on one order in compare to known methods.
