The invention relates to a method for realizing synchronization by modulating an SPROTT chaotic signal by adopting a fuzzy rule, which belongs to the technical field of communication and comprises thefollowing steps that: a signal sending end constructs a driving chaotic system through an SPROTT equation and the fuzzy rule of the signal sending end; the signal sending end encrypts the to-be-encrypted signal by using the driving chaotic system to obtain an encrypted signal, and sends the encrypted signal to the signal receiving end; a signal receiving end constructs a response chaotic system,and drives the chaotic system and the response chaotic system to construct an error signal and a synchronization rule according to the encrypted signal; and the signal receiving end adjusts the errorthrough the synchronization rule, so that the error among the encrypted signal, the driving chaotic system state and the response chaotic system state is zero, and synchronization of the to-be-encrypted signal is further realized. According to the method, the structure and state signals of the chaotic system are more complex, so that a chaotic system is more difficult to crack by an intercepting party when used for secret communication.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a method for modulating SPROTT chaotic signals by using fuzzy rules to realize synchronization. Background technique [0002] Due to the good random-like characteristics of the chaotic system, it also has rich frequency characteristics and complex and changeable dynamic characteristics. At the same time, the chaotic system can generate uncertain random-like data from definite differential equations, so it is widely used in information concealment. and information encryption. Especially, the way of realizing secure communication by chaotic synchronization of receiver and receiver by using driven response mode has been extensively studied in recent decades. [0003] However, this method still has potential safety hazards that are easy to be cracked during data transmission, so how to further improve the security of data during transmission has become an urgent problem to be ...
