Design and Implementation of Memristor-based Chaotic Synchronization under a Single Input Controller

A memristor-based chaotic synchronization circuit is designed and implemented under a single-input controller, and it is applied to secure communication based on memristor chaotic synchronization. Firstly, based on the chaotic synchronization theory, a chaotic synchronization system and secure communication model are constructed, and a fourth-order memristor-based chaotic circuit is implemented, the chaotic en-/decryption circuit is also designed. Secondly, the proposed memristor-based chaotic circuit is considered as the chaotic drive and response circuits, and a single-input chaotic synchronization controller is designed according to their error system, and it is implemented in the memristor-based chaotic synchronization circuit. Finally, many experiments of chaotic synchronization and secure communication based on chaotic synchronization are performed, and experimental results show that the proposed memristor-based chaotic synchronization circuit has many advantages, such as simple structure, convenient operation and good waveform. Furthermore, secure communication based on chaotic synchronization has high signal recovery capability and good anti-decipher ability, so that it has certain theoretical significance and potential practical value. © 2022, Science Press.
