基于混沌魔方调节的压缩传感DNA图像加密
Compression Sensing DNA Image Encryption Based on Chaos Rubik's Cube Adjustment
摘要
Abstract
In order to improve the security and reconstruct image quality during image encryption transmission,an observation matrix is constructed based on an adaptive equiangular tight frames(ETF)and QR optimization.Image encryption is performed using compressed sensing DNA encoding based on rules of Knight Chess chaotic Rubik's Cube scrambling and chaotic adjustment templates.Firstly,the optimal M sequence and Hadamard matrix are screened to construct the observation matrix,and the Gram is converged to a compact framework and QR decomposition optimization through adaptive step size.Secondly,the parameters are provided for the chaotic system using the Secure Hash Algorithm(SHA),according to the proposed rules of knight move in Chinese chess and Rubik's Cube Chaos Algorithm,and the image is scrambled before dynamic DNA encoding.Finally,the proposed chaos adjustment template is used to smooth the grayscale frequency,which reduces the correlation between adjacent information to resist statistical attacks and enhance the entropy of dense image information.Therefore,the transmission security is ensured.The results show that the reconstructed image has a PSNR of 34.2642%,the information entropy is greater than 7.999 99,the correlation of adjacent information is low,and the NPCRs are close to theoretical values,which can effectively resist plaintext attacks and statistical attacks.关键词
