摘要:
采用后稀疏化方案对待加密的明文图像做压缩感知处理,利用DNA编码规则与帐篷映射产生的混沌矩阵做规则运算,将单一编码多元化,对图像进行像素扩散,最后将扩散矩阵进行分割合并处理形成密文图像. 实验结果表明,提出的图像加密方案具备强的抗攻击特性和较好的重构效果.
Abstract:
In the paper,the plaintext images are firstly compressed by compressed sensing with post sparsing scheme,and then the DNA encoding rules and the chaotic matrix generated by the tent map are used to conduct regular operations to pluralize the singular encoding and diffuse the pixels of the images. Finally,the diffusion matrix is divided and merged to form a ciphertext image. The experimental results show that the proposed image encryption scheme has a stronger anti-attacking character and a better reconstructing effect.
