Abstract


A color image encryption algorithm based on chaotic maps is proposed in this paper. The algorithm is based on two bio-operations: crossover and mutation. To enhance the robustness against differential attacks, the mutated image is subjected to scrambling process operated on the pixel values of the image using a random sequence. Experimental results show that the proposed algorithm is capable of generating encrypted images with uniform distribution of the pixel values and very low correlation coefficients of adjacent pixels. It is very sensitive to any change in the secret key values. The results show that the algorithm is robust to statistical and differential attacks.
