Abstract: Recently, great attention is paid to the use of chaotic maps in image encryption applications due their excellent randomness properties. In this paper, an efficient image encryption algorithm using a set of chaotic maps has been proposed. The proposed algorithm diffused image by a key image generated by a recently developed chaotic map called Nahrain. To evaluate the performance, MATLAB simulations are done for both the proposed algorithm and some existing algorithms in the literature while histogram, correlation, information entropy, Number of Pixel Change Rate (NPCR), and Unified Average Changing Intensity (UACI) measures are used for security analysis. The simulation results and security analysis have demonstrated that the proposed encryption system is robust and flexible. For example the amount of entropy obtained by the proposed algorithm is 7.9758, which is very close to its ideal amount: 8, and NPCR is 100%, which is the ideal value to obtain.
