Abstract
Determined generator of quasi-random sequences for flow coding comprises a first shift register, a multiplexer with information data inputs randomly connected to the outputs of the first shift register. Output of multiplexer is connected to the first input of the "exclusive OR" element, the second input of this one is connected to the last output of the first shift register, and the output of the element "XOR" is connected to the serial input of the first shift register, a second shift register with the outputs connected to the parallel load inputs of the first shift register, a clock generator the output of which is connected to synchro-inputs of the first and the second shift registers and the input of the first counter, and its output is connected to the input of the second counter, the outputs of this are connected with the address inputs of multiplexer, the block for generation of random initialization values the output of this one is connected to the third input of the element "XOR", the session key generating unit, with its output connected to the serial input of the second shift register, and a control unit, the first output of which is connected to the control input of the second shift register and the second output of the control unit is connected to the reset inputs of the first and second counters and to the control input of the first shift register, and the output device is one of the first shift register outputs. The first shift register is divided into m parts, the last outputs of the m - 1 sections of the first shift register are connected to the first inputs of the additionally included m - 1 elements "XOR" the outputs of which are connected to the serial inputs of the following sections of the first shift register, includes m - 1 counters with programmable dividing ratio, the outputs of those are connected to the second inputs of the additional elements "XOR" the synchro-inputs of the counters with programmable division ratio are connected to the output of the clock generator, the reset inputs of counters with programmable division ratio are connected to the second output of the control unit. The information inputs of the counters with programmable dividing ratio are randomly connected to the outputs of the first shift register.
