METHOD AND APPARATUS FOR SECURE DIGITAL CHAOTIC COMMUNICATION

摘要

A method and apparatus that uses control of a chaotic system to produce secu re digital chaotic communication. Controls are intermittently applied by a transmitter-encoder (12) to a chaotic system to generate the 0 and 1 bits of a digital message. A new control/no control bit stream is thereby created in which a 0 indicates that no control was applied and a 1 indicates that a control was applied. The control/no control bit stream and a prepended synchronization bit stream are transmitted, using conventional transmission technologies (14), from the transmitter-encoder to an identical receiver-decoder (16). A chaoti c system in the receiver-decoder is driven into synchrony and is subject to intermittent controls based on the control/no control bit stream, thereby causing it to generate the digital message.
