| Title | The Implementation of Synchronous Chaotic Random Number Sequence Generator and Its Applications in Signal Encryption | ||
| Keyword | |||
| Abstract | This paper develops a chaotic synchronous random number sequence generator which base on conceptual framework of chaos, the generator parts in the transmitter, including a double scroll passive chaotic circuit, and convert the chaotic signal to random number sequence of the Threshold circuit, as well as the combination of digital information signal and chaotic random number sequence of mutually exclusive or logic circuit; in the receiver, contains a synchronous chaotic signal source for the demodulation of the transmitter to send the chaotic random number sequence, and a same mutually exclusive or logic circuit as transmitter for recover the information signal. The proposed new random number sequence generator, as a result of chaotic signal is generated, therefore it have non-periodic, unpredictable and similar trajectories of random process, so as to establish a sequence of random number generator can improve the traditional sequence of the shortcomings of random number generator. In order to make the chaotic random number sequence generator have practicality, this paper use a synchronous demodulation, so that the message signal during transmission can be encrypted and restore; by the computer software SPICE simulation, then application of PROTEL DXP circuit drawing software entities to carry out the Physical circuit can verify the feasibility study of this thesis research, It is believe that providing another research direction of the future application in chaotic secure communication,. |
