Abstract

Abstract: An image encryption algorithm based on Baker map and two-chaotic system（Logistic dynamic system and Lorenz dynamic system） is presented.The algorithm splits the original image into small blocks and uses a random point as start point in baker map.The two-chaotic sequence，built with logistic system and Lorenz equation，combines with baker map to implement image encryption.This new algorithm can reduce the length of encryption sequence and enhance security of encryption.Experiments show that the algorithm is sensitive to encryption keys and can resist differential attacks.

摘要： 提出一种基于baker映射置乱、Logistic映射和Lorenz方程相结合的双混沌系统的图像加密算法。通过对图像分块，引入随机坐标，避免baker 映射将（0，0）映射到自身；将Logistic映射和Lorenz方程相结合构造双混沌映射序列，结合baker映射实现图像加密。算法可缩短单个加密序列的长度，降低单混沌映射引起的退化风险，从而提高了加密算法的安全性。实验证明算法对密钥的敏感度强，能抵御各种攻击。
