“…Many studies have been performed on the use of textual encryption algorithms for images by modifying the algorithms to adapt with image characteristics. One such option for encrypting an image is to consider a 2D array of image pixels value as a 1D data stream and to then encrypt this stream with any conventional cryptosystem [ 2 , 3 ]. This would be considered a naïve approach and usually is suitable for text and occasionally for small images files that are to be transmitted over a fleet dedicated channel [ 4 ].…”

The rapid evolution of imaging and communication technologies has transformed images into a widespread data type. Different types of data, such as personal medical information, official correspondence, or governmental and military documents, are saved and transmitted in the form of images over public networks. Hence, a fast and secure cryptosystem is needed for high-resolution images. In this paper, a novel encryption scheme is presented for securing images based on Arnold cat and Henon chaotic maps. The scheme uses Arnold cat map for bit- and pixel-level permutations on plain and secret images, while Henon map creates secret images and specific parameters for the permutations. Both the encryption and decryption processes are explained, formulated, and graphically presented. The results of security analysis of five different images demonstrate the strength of the proposed cryptosystem against statistical, brute force and differential attacks. The evaluated running time for both encryption and decryption processes guarantee that the cryptosystem can work effectively in real-time applications.

“…However, number theory or algebraic concepts based traditional ciphers, such as Data Encryption Standard (DES) (Tuchman, 1997), Advanced Encryption Standard (AES) (Zeghid et al, 1996), International Data Encryption Algorithm (IDEA) (Dang & Chau, 2000), and the algorithm developed by Rivest, Shamir and Adleman (RSA) (Cormen et al, 2001), most of which are used for text or binary data, appear not to be ideal for multimedia applications, and the reasons are:…”
