SECURE COMMUNICATION SYSTEMS BASED UPON TWO-FOLD MASKING OF DIFFERENT CHAOTIC ATTRACTORS, INCLUDING MODIFIED CHAOTIC ATTRACTORS, USING STATIC-DYNAMIC SECRET KEYS

摘要

A kind of communication system includes the part that there are transmitter the first and second drive systems to correspond to five and Lorentz such as chaos attractor. 2 times of masking unit combines the corresponding first and second chaotic masking signals to have message signale, and by dual confusedly masked message signal, passes through common signal channel. A kind of key Dynamic Time Series, based on being sent on the first chaotic masking signal back door. Receiver includes: that the first reaction system and the conduct of the second reaction system can synchronize counterpart to the first and second drive systems. Receiver is communicably coupled to public and back door, and generates and deducted the key dynamic of version, from received dual confusedly masked message signal. Second chaotic masking signal of the further build version of the receiver, and execute subtraction operation recovery message signale. One group of static keys is in each chaos attractor that transmitter and receiver include one group of specified parameter and primary condition.
