The subject of this article is to study a memristive system and modulation and demodulate the information signal in security system, a novel memristive system is presented and its dynamics are considered. Then, the adaptive synchronization control between the proposed memristive systems is demonstrated. Additionally, the original signal is modulated in a system parameter and it can be demodulated by using filter technology. Compared to previous secure systems, in this scheme, the demodulated signal can be adjusted by the adaptive filter, It has better security performance and is easy to implement in engineering.
