Large encrypting binary images with higher security. (English) Zbl 0906.68192

Summary: We present a new approach for encrypting binary images. Putting different scan patterns at the same level in the scan tree structure and employing a two-dimensional run-encoding (2DRE) technique, our encryption method can encrypt images with higher security and good compression ratio when compared to the previous results. Detailed security analysis from the combinatorial viewpoint is also given. Some experimentations are carried out to illustrate the good performance of our proposed method.
