With the advent of cloud storage and increase in transmission images through internet, images are more vulnerable to attacks of various hackers. A lot of private images are leaked from the cloud. Information security has become a major concern. Also, as the use of digital techniques for transmitting and storing images are increasing, it becomes an important issue that how to protect the confidentiality, integrity and authenticity of images. Encrypting the images is one way of dealing with this threat. Image encryption techniques try to convert original image to another image which is hard to decipher so that the image is kept confidential between users, in other words, it is essential that nobody will get to know the content without a key for decryption. This paper proposes a new approach to image encryption using circular shift in transform domain.

“…Image encryption is different from text encryption [2]. Encryption one of the effective approaches to provide the security for image data and prevent unauthorized access to information, in general the traditional encryption algorithms such as Data Encryption Standard (DES), Advance Encryption Standard (AES) and Ron Shamir Adelman (RSA), are not suitable for image encryption and exhibit some drawbacks and weakness due to the special properties of image like strong correlation between adjacent pixels, bulk data capacity and high redundancy, which makes encrypted image vulnerable and helps to attack via cryptanalysis [3]. Chaos theory is a branch of mathematics that studies the behavior of complex dynamic systems which are highly sensitive to change in their parameters and give unpredictable results.…”

Due to the rapid evaluation in the field of communications and multimedia and the increasing use of the Internet, multimedia data security has become very urgent. of the best alternative way to achieve multimedia data security is encryption, which prevents unauthorized entities from accessing confidential data. In recent years, the chaotic system of image encryption becomes an efficient way to encrypt images due to its high security. It has certain special properties like sensitivity to initial conditions, and control parameters, pseudorandom, ergodicity, and non-convergence, etc. chaotic dynamics systems became a promising alternative to traditional encryption algorithms. In this paper, This paper presents a new algorithm for the image encryption/decryption scheme depended on a novel six-dimensional hyper-chaotic system to achieve a high level of security, the chaotic sequence generated from system employ for permutation and diffusion the original image to create an encrypted image. The performance of the algorithm has been analyzed through analyzes statistical such as Histogram Analysis, Correlation Coefficient Analysis, Information Entropy Analysis, Key Space Analysis, Key Sensitivity Analysis, Number of Pixels Change Rate (NPCR), Unified Average Changing Intensity (UACI), Peak Signal to Noise Ratio, The experimental results show that the algorithm has good encryption performance, large keyspace equals to and the high sensitivity for small changes in secret key which makes the algorithm immune to Brute force attacks, and it can resist the statistical attacks, therefore, the presented encryption algorithm depends on a novel hyperchaotic system is more secure against the statistical and differential attacks.
