A Digital Image Scrambling Method Based on Serpent

The need for distribution of digital medical images over networks has become an essential part of every day life in medical systems. There are two main factors behind this phenomenon. A new scrambling method of true color images based on Serpent algorithm is proposed. It takes the structure of true color images into full consideration, and decreases the complexity. The analytical method of cryptography is first used in this paper to analyze the security of disordering images; at the same time, Experimental results show that the method is safe, efficient and has great ability of color images.
