Abstract-The existing traditional cryptosystems, such as RSA, DES, IDEA, SAFER and FEAL, are not ideal for image encryption because of their slow speed and ineffectiveness in removing the correlations of the adjacent pixels. Meanwhile chaos-based cryptosystems, which have been extensively used over the past two decades, are almost all based on symmetric cryptography. Symmetric cryptography is much faster than asymmetric ciphers, but the requirements for key exchange make them hard to use. To remedy this imperfection, a hybrid-key based image encryption and authentication scheme is proposed in this paper. In particular, ergodic matrices are utilized not only as public keys throughout the encryption/decryption process, but also as essential parameters in the confusion and diffusion stages. The experimental results, statistical analysis and sensitivity-based tests confirm that, compared to the existing chaos-based cryptosystems, the proposed image encryption scheme provides a more secure means of image encryption and transmission.

“…In their system, two a general cat-map is used for permutation and diffusion, as well as the OCML (one-way coupled map lattice), which is applied for substitution. These two methods are operated alternately in every round of encryption process [1]. In our altered method the original images should be partitioned or merged into N× 2N pixel blocks at first.…”

Cryptographic techniques are in demand due to vast development in application of information transmission and communication. Image encryption and authentication schemes have been continuously studied to meet the demand of secure image transmission through networks. A number of effective chaos-based image encryption and authentication schemes have been proposed. The intent of this paper is to propose an image encryption and authentication scheme using chaotic map. Arnold cat map is used for diffusion as well as for substitution. This paper applies an alternate structure of the classic block cipher applied with Arnold Cat map is used for encryption and hash function is used for Authentication purpose. The paper that is being followed uses a keyed hash function is introduced to generate hash values from both the plain-image and the secret hash keys [1], which leads to large computational time, whereas our schemes computational time is less as compared to the previous. The experimental results show that the proposed encryption technique is efficient and has high security features.

“…Huaqian Yang et al [8]crypt analyzed some chaos-based image encryption algorithms with substitution-diffusion structure and identified the common flaws or deficiencies of these algorithms. The summarization of the flaws is (a) the key for encryption/decryption is independent of the plainimage and this favors known plaintext and chosen plaintext attacks, (b) in the diffusion process, the change in the current pixel value only affects a few cipher image pixels in one round and so at least two overall rounds of substitutiondiffusion are required and (c) it is difficult for the receiver to determine whether the decrypted image is exactly the one sent.…”

A Novel Framework for Image Encryption using Karhunen-Loeve Transform

The Karhunen-Loeve (KL) transform is widely used technique for image compression or clustering analysis. Since KL transform is a reversible linear transform, a novel cryptosystem is developed to provide confidentiality service for images. The original image (x), in the form of square matrix, is given as input to the KL transform which in turn produces the encrypted image (y) and the decryption key (k). Since the key matrix (k) plays a major role for decryption, it is encrypted by the receiver's public key by using RSA algorithm. The encrypted image (y) and key matrix (k) are transmitted over the public network. On receiving the encrypted image (y) and key matrix (k), the receiver takes the transpose of the decrypted key matrix (k) and multiplies the result with the encrypted image (y) to get the original image (x). The time complexity of the proposed scheme is calculated separately for both encryption, O(n 2 ), and decryption, O(n 3 ). The histograms of the encrypted images are almost uniform and different from that of the original images. This method of image cryptosystem is more suitable for small images.
