RANDOM NUMBERS GENERATION METHOD Russian patent published in 2005 - IPC

FIELD: cryptography.

SUBSTANCE: method includes generating random numbers with use of displacement register with check connection, elementary digit of which is a q-based symbol (q=2^l, l - binary symbol length) at length of q-based digits register, in check connection networks nonlinear two-parameter operations on q-based symbols F (u_b, u_d) are used, on basis of random replacement tables, for generating next random number values z₁=F(u_i, u_j), z₂=F(u_t, u_m), z_g=F(z₁, z₂) are calculated, where u_i, u_j, u_t, u_m - values of filling of respective register digits, value of result in check connection networks z_g is recorded to g digit of displacement register and is a next result of random numbers generation, after which displacement of register contents for one q-based digit is performed.

EFFECT: higher speed and efficiency.
