Image Encryption Algorithm Based on Double Scrambling

In the process of image processing, the scrambling algorithm has an important impact on image security transmission and secure storage. The traditional scrambling algorithm has high time complexity, short transform period, and inconspicuous scrambling effect. This paper proposes a double-encryption scrambling algorithm based on order adjustment. The newly constructed position scrambling method is used to encrypt the image, which greatly increases the amount of keys and can effectively resist illegal attacks. The simulation results show that the algorithm has a good scrambling effect, and the algorithm has the advantages of low similarity and high scrambling, which increases the security of the image.
