Abstract

The invention discloses a multi-scroll chaotic signal generator based on a time delay function sequence, and the multi-scroll chaotic signal generator is characterized in that the multi-scroll chaoticsignal generator comprises a basic chaotic signal generation circuit N1 and a sequence generator N2, and the basic chaotic signal generation circuit N1 is provided with an x signal output end, a y signal output end, a z signal output end and a-f (x) signal input end. The input end of the sequence generator N2 is connected with the x signal output end, and the output end of the sequence generatorN2 is connected with the-f (x) signal input end. Through the sequence generator N2 for generating the time delay function sequence and the basic chaotic signal generation circuit N1, hardware is simpler and easier to implement, multiple multi-scroll signals are generated, the encryption strength is high, and the decoding resistance is high. The method is mainly used for communication encryption.

Description

technical field [0001] The invention relates to the technical field of chaotic communication, in particular to a multi-scroll chaotic signal generator based on a time-delay function sequence. Background technique [0002] With the deepening of the research on chaotic phenomena, it is found that the pair of chaotic systems has the characteristics of high sensitivity and dependence on initial conditions and parameters, and unpredictability. Therefore, the generation and control of chaotic signals has become an important direction in the study of chaotic phenomena. [0003] The existing multi-scroll chaotic signal generator has a complex hardware structure, and the generated key space is small, the number of scrolls is small, the encryption strength is not high, and the anti-deciphering ability is low. Contents of the invention [0004] The purpose of the present invention is to provide a multi-scroll chaotic signal generator based on time-delay function sequence to solve on...
