Abstract
In this paper, we propose the image encryption method using complemented MLCA based on 90/150 NBCA(Null Boundary Cellular Automata). The encryption method is processed in the following order. First, complemented MLCA, which is derived from linear LFSR, is used to produce a PN(pseudo noise) sequence, which matches the size of the original image. Then, the created complemented MLCA sequence goes through a XOR operation with the original image to become encrypted. Lastly, an experiment is processed to verify the effectiveness of this method.
본 논문은 90/150 NBCA(Null Boundary Cellular Automata)에 기반한 여원 MLCA(Maximum Length Cellular Automata)를 이용하여 영상을 암호화하는 방법을 제안한다. 암호화 방법은 먼저 선형 MLCA에서 유도된 여원 MLCA를 이용하여 원 영상의 크기만큼 PN(pseudo noise) 수열을 생성한다. 그 후 생성된 여원 MLCA 수열을 원 영상과 XOR 연산하여 암호화를 한다. 마지막으로 실험을 통하여 본 방법의 유효성을 검증한다.
