Digital Image Encryption Base on the Chaotic Orbit Ergodicity of Arnold Transformation
Yonghong Chen · Microcomputer applications · 2009
A novel image encryption scheme based on the chaotic orbit ergodicity of Arnold transformation is proposed.The proposed scheme can enlarge the key space greatly and improve the scrambling degree as well.In addition,the coupled ma Plattice ma Pis applied on the diffusion process to improve the security of the encryption system.Experiment results show that the encryption scheme owns good encryption effect and high security.It can resist statistic attack;it is robust against JPEG compression,cropping attacks and so on as well.
