PSEUDORANDOM NUMBER GENERATOR Russian patent published in 2021 - IPC G06F7/58 

FIELD: computer technology.

SUBSTANCE: invention relates to computer technology and telecommunications and is intended for solving problems of protecting computer information. The pseudorandom number generator, consists of N D-triggers, N adders modulo two, the first group of (N-1) elements AND, additionally contains the second and third groups of N elements AND and the element OR-NOT, the output of which is connected to the first inputs of all elements AND of the second group, the second inputs of which form the second group of N key inputs of the generator, the output of the first element AND of the second group is connected to the second input of the first adder modulo two, the third inputs of adders modulo two form the third group of N key inputs of the generator, the outputs of (i+1)-x elements And (i+1) of the second group are connected to the fourth inputs of the (i+1)-th adders (i+1) modulo two, the outputs of j-th D-triggers are connected to the first inputs of j-th elements AND j of the third group, the second inputs of which form the fourth group of N key inputs of the generator, and the outputs are connected to the input of the element OR-NOT.

EFFECT: increase in the safety of using the device by complicating the analysis of its functionality by unauthorized persons.
