基于耦合混沌系统和细胞自动机的图像加密算法
Couple chaos system and cellular automata based image encryption algorithm
摘要
Abstract
This paper proposed a new kind of data encryption method based on couple chaos system and couple CTCA. Couple chaos system had more better encryption performance because of its much larger key space and chaotic characteristic. CTCA was used by way that plain data was divided into two parts and encrypted by two TCA systems respectively, which could improve the encryption efficiency and expand key space. After encrypted by chaos system, encrypted the original data by CTCA again. Experiments show that this method has a large key space and good scrambling effect and the cryptosystem can resist brute attack and differential attack effectively.关键词
