Image Encryption Based On Chaotic Scrambling And DNA Sequence Multi-rule Coding

An image encryption algorithm based on chaotic scrambling and DNA sequence multi-rule coding is proposed. Through the research of related algorithms, the original image and the chaotic sequence generated by Logistic chaos are encoded, fused and decoded by using the multi-rule coding principle of DNA sequence, and the pixel value is changed to encrypt. Then, the PWLCM algorithm is used to generate new chaos to scramble the pixel blocks of the image, so as to obtain the encrypted image. The experimental results show that the algorithm not only improves the encryption efficiency of the traditional encryption algorithm, increases the key space, but also resists the exhaustive and statistical attacks.
