A Two-dimensional Chaos Images Encryption Method Based on Baker Mapping
Huang Wen-pe · Microcomputer Information · 2008
At present,the theory of image encryption used chaos mapping is mature. For getting better results the chaos systems must go through the numerous iterations if we achieve the image scrambling by using one-dimensional chaos mapping,so it’s complex and slow. And we have a more efficient and concise method by using two-dimensional chaos mapping,so the paper gives a kind of two-dimensional new method Based on Baker Mapping. The mapping can avoid the afflicts of location,and it has nothing to do with the initial but to parameters,moreover,the chaos system that has larger space and quicker image scrambling speed is stable.
