Abstract

In this paper, a new method for image encryption based on chaotic system is proposed. An unpredictable chaotic sequence is generated by Logistic-map, and its characteristics of pseudo-random and sensitiveness to the initial condition helps to construct transformation matrix for image encryption. And two images are used together to encrypt each other in the proposed method for the sake of higher security. An example is used to demonstrate the effectiveness of the proposed method.
