In this paper, we introduce a generalized synchronization method and secure communication in the State-Controlled Cellular Neural Network (SC-CNN). We make a SC-CNN using the n-double scroll. A SC-CNN is created by applying identical n-double scroll or non-identical n-double scroll and Chua's oscillator with weak coupled method to each cell. SC-CNN synchronization was achieved using GS(Generalized Synchronization) method between the transmitter and receiver about each state variable in the SC-CNN. In order to secure communication, we have synthesizing the desired information with a SC-CNN circuit by adding the information signal to the hyper-chaos signal using the SC-CNN in the transmitter. And then, transmitting the synthesized signal to the ideal channel, we confirm secure communication by separating the information signal and the SC-CNN signal in the receiver.

In this paper, we introduce a hyper-chaos synchronization method using State-Controlled Cellular Neural Network(SC-CNN). We make a hyper-chaos circuit using SC-CNN with the n-double scroll. A hyper-chaos circuit is created by applying identical n-double scrolls with weak coupled method, to each cell. Hyper-chaos synchronization was achieved using drive response synchronization between the transmitter and receiver about each state variable in the SC-CNN.

In this paper, we use hyper chaos circuit which is made through the phase differences which is generated during the process of weak-coupling of CNN between two and more chaos attractors. Notwithstanding the complexity of the hyper chaos, we could do the synchronization and according to it, Secure communication through this method coo]d be accomplished. On this research, we configurated 2-double scroll and 3-double scroll circuit ,not using Chua circuit, but SC-CNN(State-Controlled CNN) which is more flexible to configure the system.

In this paper, we introduce a hyper-chaos synchronization method using State-Controlled Cellular Neural Network(SC-CNN). We make a hyper-chaos circuit using SC-CNN with the n-double scroll. A hyper-chaos circuit is created by applying identical n-double scrolls with weak coupled method, to each cell. Hyper-chaos synchronization was achieved using drive response synchronization between the transmitter and receiver about each state in the SC-CNN. From the result of the recovery signal through the demodulation method in the receiver, We shown that recovery quality of state variable $$\chi$_3$ is superior to that of ${$\chi$_2}, {$\chi$_1}$ in secure communication.

In this paper, we introduce embedding drive synchronigation method using SC-CNN. SC-CNN provide us a good method to separate interconnected state variables of a system respectively and to make it possible to change current component to voltage component in the state variables. Using this advantage, We suggest another synchronization method called Embedding Drive Synchronization. Proposed Embedding Drive Synchronization change general drive synchronization method a little bit. we put transmitted signal between into the input of the state variables of the received part, not entirely replacing it. and we showed it proved.

본 논문에서는 SC-CNN의 특성을 이용한 임베딩 구동 카오스 동기화 방법을 소개한다. SC-CNN은 Chua 회로의 미분방정식에서의 세가지 상태변수중 전류성분과 같이 동기화와 신호 합성에 어려운 상태변수를 전압성분으로 분리하여 다룰 수 있는 방법을 제공하고있다. 여기서 지금까지 이용되 오던 결합 동기나 구동동기화의 방법에 새로운 임베딩 구동 동기 방식을 제안한다. 제안하는 Embedding Drive Synchronization(임베딩 구동동기)은 구동동기에서 미분상태변수를 완전히 대체하는 것이 아닌 한 성분만을 대체하여 구성되며 그 타당성을 검증하였다.

In this paper, We introduce an embedding driven synchronization method using SC-CNN(State-Controlled Cellular Neural Network) which has the purpose to secure communication method through the embedding driven synchronization method in the SC-CNN. we proposed new embedding driven synchronization that this method is only using one state variable compare to the general driven synchronization methods which is using all state variables. In this paper, We achieved the usage of embedding driven synchronization and we also applied it to secure communication.
