The invention discloses a multi-wing chaotic signal generator based on step wave switching control. The generator comprises a basic chaotic signal generation circuit N1, a basic chaotic signal generation circuit N2 and a sequence generator N3 for generating a switching control function. The output end of the basic chaotic signal generation circuit N1 is connected with the input end of the sequence generator N3; the output end of the basic chaotic signal generation circuit N2 is connected with the input end of the sequence generator N3; the output end of the sequence generator N3 is connected with the input end of the basic chaotic signal generation circuit N1 and the input end of the basic chaotic signal generation circuit N2. Through adoption of the sequence generator N3 for generating the switching control function, the multi-wing chaotic signal generator based on step wave switching control is easier to realize. According to the generator, a multi-wing chaotic system can be generated; and the chaotic encryption performance is higher.
