Abstract

1,270,583. Cyphering systems. CESKOSLOVENSKA AKADEMIE VED. 7 May, 1969 [8 May, 1968], No. 23348/69. Heading H4P. [Also in Divisions G4-G6] Random pulses are applied to outputs 16-20 through the system shown from a random pulse generator 1, the system including a number of selectors or switches 6-14 movable to make or break combinations of circuits. A probability changer 2 is operated by a plurality of frequencies to produce Markow chains. An input 15 of control pulses sometimes affects a flip-flop 5 controlling switch 6. A counter 4 can be programmed to produce a pulse at predetermined values. The system may be used for cyphering telegraph messages.
