Description

technical field

[0001] The invention relates to a chaotic signal generator, in particular to a chaotic signal generator based on the random switching of the number of wings realized by FPGA. Background technique

[0002] Compared with the chaotic signal generator with a fixed number of wings, the multi-wing chaotic signal generator has complex dynamic behavior and unpredictability, so it can be widely used in chaos-related security systems. At present, there are many chaotic signal generators based on multi-wing chaotic systems, but the current multi-wing chaotic signal generators all use a fixed number of wings, which limits their application in secure communication. Contents of the invention

[0003] In order to solve the above technical problems, the present invention provides a chaotic signal generator with simple structure and good security effect based on random switching of the number of wings realized by FPGA.

[0004] The technical solution of the present inventi...
