Method and apparatus for secure digital chaotic communication

(57) The method and equipment which are used in order to control the chaos system for performing summary safe digital chaos communication. Control is intermittently applied to a chaos system by the transmitter encoder (12), and generates the digital message of the bit of 0 and 1 by it. New control / non-controlling bit stream are generated by that cause, and control is not applied 0, but 1 shows that control is applied. The synchronous bit stream added control / non-controlling bit stream, and before that is transmitted to receiver decoders (16), such as a phase, from a transmitter encoder using the usual transmission technology (14). The chaos system in a receiver decoder is driven synchronically, and receives the intermittence control based on control / non-controlling bit stream. Then, a digital message is made to generate.
