Summary:Image encryption schemes based on chaotic maps and systems have been investigated for more than one decade. However, many proposed schemes that obtained good score in the statistical tests, i.e. number of pixel changing rate and unified average changed intensity were proven to be insecure against differential cryptanalysis. Differential cryptanalysis is a chosen plaintext attack that utilizes the high probabilities of occurrence of a specific plaintext-ciphertext difference. In this paper, we present the weaknesses of these image encryption schemes against differential cryptanalysis and discuss how a cryptanalyst can exploit them to demonstrate the security deficiency of the schemes.
