An Image Encryption Scheme Based on TD-ERCS Chaotic System
Yuanming Jian · Journal of Southwest China Normal University · 2012
A secret key matrix was generated by 2-dimensional discrete chaotic sequence of the TD-ERCS,and the scheme was improved by Hill cipher to change the pixels of the image.With our encryption algorithm,a grayscale image and a color image were simulated separately by Matlab.Correlation analysis of the grayscale histogram and pixels of the image encryption proved that the dark texts have high perturbative and low relativity,thus indicating that our encryption algorithm is fairly preferable and secure.
