A new image encryption algorithm based on ladder transformation and DNA coding

In this paper, a new scrambling algorithm is proposed to reduce the correlation between the image pixels in three directions. In this paper, this algorithm is called ladder scrambling, and the image is scrambled multiple times in the form of diagonal lines. In terms of diffusion, DNA coding is used,...

Description
Summary:In this paper, a new scrambling algorithm is proposed to reduce the correlation between the image pixels in three directions. In this paper, this algorithm is called ladder scrambling, and the image is scrambled multiple times in the form of diagonal lines. In terms of diffusion, DNA coding is used, and the secondary processing of the image is performed through DNA coding to change the pixel value of the image. The final encrypted image is affected by three conditions: the number of scrambling algorithms, the selection of DNA coding rules, and the key of the chaotic system. Theoretical analysis and experimental results show that the algorithm is safe and effective.
