Abstract

The invention relates to a color image encryption method and device, computer equipment and a readable storage medium, and the method comprises the steps: obtaining an initial parameter and a controlparameter of a chaotic system, and generating a replacement chaotic sequence and a diffusion chaotic sequence according to the initial parameter and the control parameter; dividing the original colorimage into a high-bit plane and a low-bit plane according to the information amount; according to the replacement chaotic sequence, carrying out scrambling operation on the high bit plane and the lowbit plane according to different scrambling strategies to acquire a scrambled image; and performing diffusion operation on the scrambled image according to the diffusion chaotic sequence to obtain anencrypted image corresponding to the original color image. Due to the fact that the high bit plane and the low bit plane contain different amounts of information, scrambling operation is conducted onthe high bit plane and the low bit plane through the weight grading replacement strategy, and the safety of scrambling operation is enhanced while the algorithm efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of image encryption, in particular to a color image encryption method, device, computer equipment and readable storage medium. Background technique [0002] With the rapid development of digital technology and computer networks, digital images have become one of the main ways of information expression and transmission, and are more and more applied to various fields such as politics, economy, military affairs, and education. People can easily transmit information through the network. Various image information. However, since digital information is extremely easy to be copied, tampered, illegally disseminated, and intentionally attacked, people have higher requirements for the security and confidentiality of information transmission while enjoying the speed and convenience of information transmission. [0003] The research on image encryption based on chaos theory is of great significance. Image e...
