Chaos synchronization apparatus by modulating the delay time and the communication apparatus using them

摘要

The present invention in order to to generate a delay time modulated two identical chaotic system, the same signal to each other relates to a synchronization device and a communication device for synchronizing the chaos device, the initial value changes to create the different chaos signal using the same synchronizing two chaotic systems by a delay time modulated and, to a synchronization device of this chaos chaos device to encrypt, decrypt the information signal using the chaos signal generated in the device and a communication device using the same. The invention To this end, the state chaos variable device in accordance with some chaotic system that is functionally connected to each other for generating at least one chaotic signal having chaotic properties, is configured the same as the state chaos device, the main chaos in the chaotic system of the dependent chaos device for generating a chaotic signal corresponding to the chaotic signal to the device generating the modulation signal generation means for generating a modulation signal, a first of the time delay the chaos signal generated by the said main chaos device time delay means, a first delay time modulation sudanwa that modulates the delay time output from the first delay means the time-delayed chaotic signal to the modulation signal from the modulation signal generation means, confusion resulting from the dependent chaos device second delay time modulation means for modulating the delay time output from the delay means and the second time, the second time delay means, said time-delayed chaos signal for time delay a signal to the modulation signal from the modulation signal generation means; and a first synchronization unit which, in addition to at least one chaos signal for generating a delay time modulation from the first delay time modulation means from the state chaos device feedback to the state chaos device, the second delay modulated from time modulation means It has been made to delay the synchronization in a second state in response to any chaotic one chaos signal generated from the apparatus in addition to the chaos signal generated from the slave device to the chaos feedback to the device dependent chaos. ; Synchronization device, encryption device, a decryption device, the chaos system, the time delay
