Multimedia security has become a serious issue in todaypsilas highly computerized and interconnected world. Pareek et al. recently proposed an image encryption scheme based on multiple 1D chaotic logistic maps. However, it has been shown in [8] that the proposed scheme is insecure against the chosen-plaintext attack and also has some other security defects. Here a modified scheme is propose based on a key dependent S-box and ciphertext feedback. The modified scheme efficiently fulfills the need of real-time image encryption, while at the same time it is secure against the differential and linear cryptanalysis.
