摘要
综述了一些传统图像加密体制以及目前研究应用较多的图像加密技术。简述了两大密钥体制的发展情况,分析了基于矩阵变换和像素置乱的图像加密技术。介绍了混沌理论在图像加密中的应用,同时包括与混沌系统并用的其他加密技术,如基于DNA编码的混沌图像加密、基于压缩感知的混沌图像加密,以及基于光学成像的混沌图像加密。阐述了各加密技术的特点及其应用情况,分析其优缺点。对未来的发展趋势做出假设。
In this paper, some traditional image encryption systems and image encryption techniques that are currently researched and applied are reviewed. The development of the two key systems is briefly described, and the image encryption technology based on matrix transformation and pixel scrambling is analyzed. The application of chaos theory in image encryption is introduced, and other encryption techniques used with chaotic systems are also included, such as chaotic image encryption based on DNA coding,chaotic image encryption based on compressed sensing, and chaotic image encryption based on optical imaging. The characteristics and application of each encryption technology are expounded, and its advantages and disadvantages are analyzed. Assumptions are made about the future development trend.
