A block image encryption algorithm on coupled map lattice
Yanbing Zhang · 2012
Aimed at the problems that traditional digital image encryption algorithm based on chaos performs weak in anti-differential cryptanalysis and has poor effect on recovery of impaired encryption image,a digital image encryption algorithm based on block cipher and alternating iteration structure is designed,which adopts different CML to form S-box during each round of encryption,bringing better security performance to the algorithm.Experiment results show that the algorithm not only possesses well encryption effect,but also very useful for the recovery of impaired encryption image.
