A Noval Image Encryption Algorithm Based on DNA sequence operation and Chaotic System
Chen Chen, Lanlan Li · 2023
The digital image stores the important information, so it’s extremely important to protect the security of image information transmission. This paper proposes a noval digital image encryption algorithm based on insert-delete model and 2D Logistic chaotic system. In the first step, the original image is divided into four sub-images by quaternary coding, and each sub-image is coded separately. This can improve the security of the encryption algorithm, because the attacker can only recover useful information if he obtains all the sub-images. In addition, 2D logical chaotic system is used in the encryption scheme, which has a large key space. Experimental data and simulation results show that the scheme has high security, can resist exhaustive attacks, statistical attacks and differential cryptanalysis, and has good encryption effect.
