Image Encryption Techniques (2011)

This paper lays down the various image encryption techniques and specifically gives an account of chaos based encryption of images. The kinds of techniques studied include image encryption using digital signatures, lossless image compression and encryption using SCAN, mirror like image encryption, chaotic image encryption and colour image encryption using double random phase coding. Image encryption is different from text encryption because of the larger scale of data, higher redundancy and stronger correlation of pixels in images. Hence traditional encryption algorithms are not suitable for digital image encryption. To overcome these drawbacks we present a chaos based algorithm for images. This algorithm is based on scrambling of pixels where the randomness of chaos is utilized. The data are scrambled in the order of randomness of elements based on the chaotic map and reshuffled again to their original positions in the decryption process. Compared to traditional methods, chaotic image key encryption has a larger space, simple implementation, robustness and the advantages of faster encryption.

Chaos Image Encryption Methods: A Survey Study

Bulletin of Electrical Engineering and Informatics, 2017

With increasing dependence on communications over internet and networks, secure data transmission is coming under threat. One of the best solutions to ensure secure data transmissions is encryption. Multiple forms of data, such as text, audio, image, and video can be digitally transmitted, nowadays images being the most popular and old encryption techniques such as: AES,DES,RSA etc., show low security level when used for image encryption. This problem was resolved by using of chaos encryption which is an acceptable form of encryption for image data. The sensitivity to initial conditions and control parameters make chaos encryption suitable for image applications. This study discusses various chaos encryption techniques.

A Survey of Image Encryption Algorithms

3D Research, 2017

Security of data/images is one of the crucial aspects in the gigantic and still expanding domain of digital transfer. Encryption of images is one of the well known mechanisms to preserve confidentiality of images over a reliable unrestricted public media. This medium is vulnerable to attacks and hence efficient encryption algorithms are necessity for secure data transfer. Various techniques have been proposed in literature till date, each have an edge over the other, to catch-up to the ever growing need of security. This paper is an effort to compare the most popular techniques available on the basis of various performance metrics like differential, statistical and quantitative attacks analysis. To measure the efficacy, all the modern and grown-up techniques are implemented in MATLAB-2015. The results show that the chaotic schemes used in the study provide highly scrambled encrypted images having uniform histogram distribution. In addition, the encrypted images provided very less degree of correlation coefficient values in horizontal, vertical and diagonal directions, proving their resistance against statistical attacks. In addition, these schemes are able to resist differential attacks as these showed a high sensitivity for the initial conditions, i.e. pixel and key values. Finally, the schemes provide a large key spacing, hence can resist the brute force attacks, and provided a very less computational time for image encryption/decryption in comparison to other schemes available in literature.
