Lorenz Chaotic Encryption of Color Digital Image
Dinghui Zhang · Microcomputer Information · 2012
Based on the feature of digital image encryption processing and high-dimensional chaotic sequences,this paper proposed a color digital image encryption algorithm by using Lorenz chaotic map.This algorithm uses the RK method to solve the Lorenz equation in order to get the real value sequences.Then respectively encrypt three-color components of color image which are R,G and B by the sequences using the exclusive or operation.The algorithm is extremely sensitive to initial values,and can produce a very nice encryption effects after adding a control factor.The experimental results and its safety analysis confirm it's a good encryption with better effects and can effectively resist statistical attack.
