“…In detail, the asymmetric method of encryption is essential to complete the process by using a public key [3] and in pertaining to the SKE (Symmetric Key Encryption) the common key will be exchanged among the transceiver nodes. When compared between both the kind of encryption techniques, SKE criteria is found to be effective, simple, and faster for the macro image size, but the key management is crucial for SKE, as the key among the sender and receiver need to be safely communicated in the communication system defending with the untrusted intruder [7,8,9]. Whereas on the other side of the PKE (Public Key Encryption) will ensure the various issues by addressing a pair of keys such as private and public keys that are securely used for decryption and encryption activities respectively.…”

In this era of the digital world, handling digital data with a secure passion is more important. At the height of maximum interest with the attainment of the data confidentiality with the miniature information is the tedious and most challenging concern of the system with the data handling and operating in the real-time environment. With the latest data confidentiality security model, such as image encryption over the communication networks in the distributed data environment, advanced hacking efforts such as cropping attack, brute force, differential, mathematical, and many more need to be addressed. In terms of bit scrambling, the security function plays a vital role in the pixel-based approach with minimum pixels are followed in the current security model for a better correlation with the available pixels with the continued higher runtime complexity. In this research paper, along with the DNA encoding process, an efficient image cryptographic technique is shown with the reduced runtime complexity. The discussion in the article begins with the chaotic sequence EIIS (Efficient Image Information Scrambling) method. Progressed with the DNA (Deoxyribo Nucleic Acid) encoding is done with the data for resistance against different kinds of attacks by considering the suitable parameters from the existing security models.

“…A number of image encryption schemes have been developed using different approaches [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. Hua et al [ 12 ] developed a highly secure image encryption algorithm, where pixels are shuffled via the principle of the Josephus problem and diffusion is obtained by a filtering technology.…”

We propose an image encryption scheme based on quasi-resonant Rossby/drift wave triads (related to elliptic surfaces) and Mordell elliptic curves (MECs). By defining a total order on quasi-resonant triads, at a first stage we construct quasi-resonant triads using auxiliary parameters of elliptic surfaces in order to generate pseudo-random numbers. At a second stage, we employ an MEC to construct a dynamic substitution box (S-box) for the plain image. The generated pseudo-random numbers and S-box are used to provide diffusion and confusion, respectively, in the tested image. We test the proposed scheme against well-known attacks by encrypting all gray images taken from the USC-SIPI image database. Our experimental results indicate the high security of the newly developed scheme. Finally, via extensive comparisons we show that the new scheme outperforms other popular schemes.

“…Subsequently, the gyrator transform is introduced to enhance the DIE technique cooperated with iterative random binary encoding [19], pixel scrambling [20,21], and iterative phase retrieval algorithm [22]. Meanwhile, discrete fractional random transform (DFrRT) is also proved to be an effective approach to DIE [23,24]. Besides, the asymmetric strategy with phase truncation (PT) has been employed in DIE [25,26,27].…”

A double-image asymmetric cryptosystem is proposed by using cylindrical diffraction and spectrum fusion and compression in the zigzag-scanned domain of discrete cosine transform (DCT). First, each plaintext of double image is converted into spectrum coefficients (SCs) by DCT, and the SCs are zigzag scanned. Second, the first 1/4 of SCs is resized to two low-frequency images, the second 1/4 of SCs is resized to two high-frequency images, while the last 1/2 of SCs is discarded. Third, the two low-frequency and two high-frequency images are fused and merged into three rounds of encryption process by using the complex combination, random phase encoding, and phase reserving-truncation in the cylindrical diffraction transform domain. Finally, the plaintexts of the double image are successfully encrypted into a ciphertext and three private keys with each only 1/8 and totally 1/2 of the size of the plaintext, which gains a high compression efficiency. In the proposed cryptosystem, the quality of the reconstructed image is improved due to the compression in the zigzag-scanned DCT domain, and the security is improved owing to the asymmetric cylindrical diffraction and spectrum-fusion algorithm. The effectiveness and flexibility of the proposed cryptosystem have been validated by the numerical simulation results. Proposed asymmetric cryptosystem PRT in CDT domainAccording to the cylindrical diffraction theory in [32,33], the object and the observation surfaces are concentric cylindrical surfaces. Figs. 1a and b show the two, inside-out propagation (IOP)
