Research on Compound Encryption of Digital Image Based on Logistic Chaotic Sequence
Dianhong Wang · Computer and Modernization · 2005
A new encrypting method related to still digital image,which bases on Logistic chaotic sequence is proposed in this paper.This computing method harnesses the randomicity and the sensitivity of the original value of the Logistic chaotic sequence,to generate the real value sequence,and then,create the parameter sequences through the discrete mapping.The encrypting process is disturbing color values of each image point and the array of original image separately based on those parameters.The decrypting process is just the reverse of the encrypting process.Finally,this new encrypting method shows great satisfaction in the result of experiment.
