Abstract

In this paper, complexity secure communication was presented. The complexity circuit is used to State-Controlled Cellular Neural Network(SC-CNN). We make a complexity circuit using SC-CNN with the N-double scroll. A complexity circuit is created by applying identical n-double scrolls with coupled method, to each cell. complexity 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 in the receiver is the similar to other secure communication methods.

본 논문에서는 복잡계를 이용한 비밀통신 방법을 제시한다. 복잡계 회로는 N-Double Scroll CNN 회로를 이용하였다. 동일한 여러 개의 셀을 가진 N-Double Scroll 회로를 이용하여 복잡계의 송ㆍ수신부를 구성하고 이 복잡계 송ㆍ수신부 사이에 임베딩 동기화 기법을 이용하여 동기화를 이루고, 송신부에서 정보 신호를 복잡계 신호에 합성하여 채널을 통하여 수신부에 송신 한 후 수신부에서 정보 신호와 복잡계 신호를 분리하는 기법을 제시하여 비밀 통신 가능성을 확인하였다.
