New Color Image Encryption Algorithm Based on Chaos Sequences
Zi Hong · Modern Electronics Technique · 2010
A color image encryption algorithm based on the chaos sequences is proposed,which generates two chaos sequences by 2D Logistic chaos system,scrambles the position of color images by two coding sequences produced by ranking the two chaos sequences,and then carries out the scrambling operation in which the R,G,B values of pixel points of the scrambled color images are shuffled by the ranking of three chaos sequences produced by 3D Lorenz chaos system to realize the color encryption.The experimental results show that this algorithm has a large key space,high security and good conficentialty.
