基于多维混沌系统的彩色图像加密算法设计

进入21世纪,越来越多的信息在网络上传播,信息安全问题日趋明显.如何确保信息的安全成了一个新课题.由于混沌序列具有初值敏感性、伪随机性等特点,在图像加密中应用较为广泛.本文将猫映射和三维统一混沌系统结合起来,设计了一个彩色图像的加密算法,得到的密文具有较高的安全性.

Design of Color Image Encryption Algorithm Based on Multidimensional Chaotic System

At present, more and more information spread in the network, The problem of information security is becoming more and more serious and the information security is becoming a new issue. Chaos systen has pseudo-randomness, the sensitivity to initial conditions and so on a series of excellent features,so it is widely used in image encry-ption.In this paper, I designed a encryption algorithm based on generalized cat map and 3D unified chaotic system to encrypt the color iamge, and the ciphertext has higher security.
