The chaotic system is a complex nonlinear dynamic system with pseudo randomness and uncertainties, as well as the initial conditions and the extreme sensitivity of system parameters. The chaotic sequence produced by chaotic system is very suitable for information encryption such as text and digital images. An encryption method for color images based on Logistic and Henon chaotic systems is presented in this paper. The chaotic sequence is produced by the Logistic and Henon systems. The image encryption is performed by the XOR operation of the sequence corresponding to original image and the chaotic sequence.
