一种新的图像自适应并行加密算法

A New Self-adaptive Parallel Image Encryption Algorithm

  • 摘要: 提出了一种新的图像自适应并行加密算法.该算法根据奇偶加密轮次对图像进行水平或垂直分组,再对分组进行子块划分,并使用相邻块像素扰动混沌映射,同时设计了新的分组扩散方法,并使用S盒完成像素非线性替代.实验结果表明,新算法具有安全、简单、高效的特点,适合并行实现.

     

    Abstract: A new self-adaptive parallel image encryption algorithm is proposed. In the new algorithm, image is divided into horizontal or vertical groups according to encryption rounds, each group is divided into two sub-blocks, chaotic mapping of each sub-block is disturbed by adjacent sub-block pixels, a new pixel diffusion method is designed, and pixels are replaced by using S box. The experiments show that the new algorithm has the advantages of safety, simple and efficient, which is suitable for parallel implementation.
