摘　　要：为了分析信息安全问题，提出了一种改进的新型三维超混沌映射，并将其应用于图像加密算法中，首先对改进的三维超混沌进行了定义，其次分析了所提混沌系统的混沌特性，最后结合四元数及分组加密算法并将其应用于图像加密，实验结果表明，该混沌系统具有良好的混沌特性，且将其应用于图像加密中能获得较好的安全性。In order to analyze the problem of information security, an improved 3D hyper chaotic map is proposed and applied to image encryption algorithm. In this study, this hyper chaos was defined, followed by analysis of the chaotic effects, and finally, the chaos together with quaternion and grouping encryption algorithm was applied to image encryption. The experimental results show that the chaotic map has good effects and can be applied to image encryption with better security.
