摘要: 针对医学图像数据量大、同色像素连续性高的特点,提出了一种基于混沌理论的图像加密算法。算法通过在多个一维混沌系统间的随机切换产生加密序列,在加密过程中对图像本身引入了双重反馈,从而有效延长了混沌序列的周期,提高了算法的安全性。实验证明,本算法具有较好的运行效率与加密效果。
关键词: 医学图像,混沌加密,双重反馈
Abstract: Due to the characteristics of medical image; huge data and high continuity of same color pixels, a medical image encryption algorithm based on chaos theory was proposed. hhe algorithm generates encryption array by randomly switcking among multiple one-dimensional chaos systems, introduces duplex feedback to the image data while encryp-ting,which lengthens the sequence period and improves the security of algorithm. Experiment results show that the algorithm has good running efficiency and encryption effect.
Key words: Medical image,Chaos encryption,Duplex feedback
