The focus of this paper is to improve the level of security and secrecy provided by the chaotic


map based image encryption.An encryption algorithm based on the Logistic and the Henon


maps is proposed. The algorithm uses chaotic iteration to generate the encryption keys, and


then carries out the XOR and cyclic shift operations on the plain text to change the values of


image pixels. Chaotic Map Lattice based image encryption algorithm suggested by Pisarchik is


also examined which is based on Logistic map alone. In experiments, the corresponding results


showed the proposed method is a promising scheme for image encryption in terms of security


and secrecy. At the end, we show the results of a security analysis and a comparison of both


schemes.
