“…It provides an enriched security level [15,16]. Conventional block cipher algorithms are not suitable for secured multimedia communication over public networks [2,9,24,36,37]. On the other hand, DNA cryptography is gaining more attention with a variation of chaos-based substitution permutation architecture [8,16,29,30,34,36,37].…”

“…There exist many benchmarks symmetric and asymmetric cryptographic algorithms such as Advanced Encryption Standard (AES), IDEA (International Data Encryption Algorithm), and RSA (Proposed by Rivest, Shamir, and Adleman) to provide security to text data. But the survey provides evidence that these algorithms are not suitable for image encryption [2,3,10,24]. Image data characteristics like pixel correlation, bulk space, and high redundancy among pixel values make image encryption more challenging compared to text encryption [3,10].…”

In recent days, DNA cryptography is gaining more popularity for providing better security to image and text data. This paper presents a DNA based cryptographic solution for image and textual information. Image encryption involves scrambling at pixel and bit levels based on hyperchaotic sequences. Both image and text encryption involves basic DNA encoding rules, key combination, and conversion of data into binary and other forms. This new DNA cryptographic approach adds more dynamicity and randomness, making the cipher and keys harder to break. The proposed image encryption technique presents better results for various parameters, like Image Histogram, Correlation co-efficient, Information Entropy, Number of Pixels Change Rate (NPCR), and Unified Average Changing Intensity (UACI), Key Space, and Sensitivity compared with existing approaches. Improved time and space complexity, random key generation for text encryption prove that DNA cryptography can be a better security solution for new applications.

The main purpose of the data encryption process is the difficulty of understanding the content of the message with the difficulty of detecting the encryption mechanism. Therefore, in this paper, we proposed a new model of encryption based on the idea of encrypting text messages and gray images using amino acid chains. Amino acids are distinguished by being a series of alphabets represented by 20 characters and do not have a specific length. The main idea of this paper is to get an amino acid chain that contained encrypted message. To develop this model, we construct an artificial lookup table to encrypt any character of message to the amino acid chain, after that applying encryption process. The proposed model was applied on different kinds and sizes of messages, which proved the success of the main idea of the research, which is obtained amino acid chains with encrypted messages. The proposed model appears efficient in real time of encryption and extraction process compared with known methods. In the end, we compared the amino acids that we extract on the process of encrypting with internationally known amino acids and we found a similar ratio, which proves that the proposed model is effective in terms of increasing ambiguity of the encrypted message.

In this paper, a new memristor chaotic system is designed based on Chua’s memristor chaotic system. To get the complete picture of the brain of a three-dimensional chaotic attractor, red and blue 3D glasses is used to observe the chaotic attractor, and using Lyapunov exponent spectrum, SE complexity and C0 complexity to analyze dynamical characteristics of new memristor chaotic system. The results illustrate that the chaotic state of the new memristor chaotic system is distributed over a large parameter range, which shows that the new memristor chaotic system is more suitable for image encryption applications. To verify the image encryption application of the new memristor chaotic system, a novel image encryption algorithm is designed based on the new memristor chaotic system and DNA variation. The security performances of the designed algorithm indicate that the proposed algorithm can effectively encrypt image and has better security performance.
