This paper presents a composite scheme for image encryption. In the temporal domain, chaotic series acts as a key for the AES (Advanced Encryption Standards) encryption. It is used to generate and administer AES key while preserving its other nice features. In the spatial domain, we present a new method of deriving a space transform matrix with chaotic series. In both domains, the chaos series is generated by the logistic equation, whose parameter is modulated by another logistic equation with a different initial value. Therefore, short period effect is avoided in the solution sequence of the chaotic system. Finally our experimental results confirm the effectiveness of the proposed method Also, there is no damage caused to the decrypted image.
