“…Image encryption techniques can be categorized into: 1) Frequency based image encryption and 2) Spatial based image encryption. Hence, using secret key, the frequency based image encryption algorithms are developed to transform image content in the frequency domain such as the Discrete Cosine Transform (DCT) [16], Discrete fractional Fourier Transform (DFFRT) [17], [18], Quantum Fourier Transform (QFT) [19], Fresnel transform [20], Hartley Transform [21] and Gyrator Transform [22].…”

Abstract-The use of digital images in most fields of information technology systems makes these images usually contain confidential information. When these images transmitted via the Internet especially in the Cloud, it becomes necessary to protect these images in a way that ensure putting the confidential information that are contained far away from the attackers. A proposed image encryption technique has been presented in this work. This technique used a secret key that is extracted from the image content itself. Therefore, there is no need to find a secret channel to exchange any key where, sender and receiver authenticate each other with regards to a shared secret key extracted from the image. The technique constructs its secret key that is used to encrypt the image, based on the entropy values of a set of randomly selected blocks from the image itself. Vairous experiments have been conducted to evaluate the strength and performance of the technique. The experimental results shows that the proposed technique can be used effectively in the field of image security to protect and authenticate images.

“…Their method is robust of noise addition and the errors in the secret keys, which employed through decryption steps. Similarly, Lima et al [18] divided grayscale image into blocks with size 8  8 pixels. The image blocks were encrypted with a secret key based on Galois Field Fractional Fourier Transform (GFFFT).…”

“…The main idea of the transform domain-based image encryption is that the digital image is operated in the transform domain. Then the pretreated information is encrypted by using other techniques especially chaos [10,11]. The pretreatment techniques include fractional Fourier transform (FRT), Discrete Wavelet Transform (DWT), and so on.…”

Networks have developed very quickly, allowing the speedy transfer of image information through Internet. However, the openness of these networks poses a serious threat to the security of image information. The field of image encryption has drawn attention for this reason. In this paper, the concepts of 1-dimensional DNA cellular automata and T-DNA cellular automata are defined, and the concept of reversible T-DNA cellular automata is introduced. An efficient approach to encryption involving reversible T-DNA cellular automata as an encryption tool and natural DNA sequences as the main keys is here proposed. The results of a simulation experiment, performance analysis, and comparison to other encryption algorithms showed this algorithm to be capable of resisting brute force attacks, statistical attacks, and differential attacks. It also enlarged the key space enormously. It meets the criteria for one-time pad and resolves the problem that one-time pad is difficult to save.
