A Digital Image Scrambling Method Based on AES and Error-Correcting Code

A new scrambling method of true color images based on AES 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 disordered images; at the same time, an error-correcting code is designed to prevent passive attacks based on bit modification. Experimental results show that the method is safe, efficient and has great ability of error correcting.
