Image Encryption Algorithm Based on Self-Adaptive and Chaos Theory
An image encryption algorithm based on self-adaptive and chaos theory is presented. The scrambling transformation is completed with Logistic chaos and S-box first. Then self-adaptive image encryption scheme is used to deal with gray transformation for each pixel and image encryption is finished at last. Theoretical analyses and simulated experiment show that the proposed image encryption algorithm provides perfect results, larger key space, simple and easy to be implemented and fast running speed, so this encryption algorithm has excellent performance against many kinds of attacks and has strong practicality.
