Abstract

Information security has become a major challenge with the advent of cloud and social networking sites. Conventional encryption algorithms might not be suitable for image encryption because of the large data size and high redundancy among the raw pixels of a digital image. In this paper, we generalize the encryption method for of color image proposed by Jeong et al. to color image encryption using parametric 3-dimensional chaotic cat map using Laplace expansion and C-MLCA. Through rigorous experiments, we demonstrate that the proposed new image encryption system provides high security and reliability.

정보 보안은 클라우드 및 소셜 네트워킹 사이트의 출현으로 주요 과제가 되었다. 기존의 암호화 알고리즘은 디지털 영상의 큰 데이터 크기와 원시 픽셀 간에 높은 중복성으로 인해 영상 암호화에 적합하지 않을 수 있다. 본 논문에서는 Jeong 등이 제안한 컬러 영상의 암호화 방법을 C-MLCA와 Laplace 전개를 이용한 매개변수식 3차원 카오스 캣맵을 사용하여 일반화한다. 제안된 새로운 영상 암호시스템이 높은 보안성과 신뢰성을 제공한다는 것을 엄격한 실험을 통해 입증한다.
