RANDOM SEQUENCE GENERATOR Russian patent published in 1997 - IPC

FIELD: computer and radio engineering; stoichastic computers for building random-number generators in cryptographic data protection systems. SUBSTANCE: random-sequence generator has field-signal generator 1, modulo two adder 2, flip-flop 3, clock generator 4, controlled asynchronous-signal generator 5, AND gate 6, second input 7 of AND gate 6, output 8 or flip-flop 3; field-signal generator 1 has n series-connected modulo 2 adders 9₁-9_n last one having its output functioning as output 10 of field-signal generator 1 which has input 12, NOT gate 11; controlled asynchronous-signal generator 5 has AND gate 13, modulo two adder 14 whose first input functions as first input 15.1 of group of inputs 15.1-15.K and also has K-1 series-connected controlled pulse shapers 16, each provided with first AND gate 17, modulo two adder 18, and second AND gate 19. EFFECT: improved reliability, quality, and speed of response of random sequence generator. 4 cl, 9 dwg
