“…In order to analyze whether the scheme in this paper could resist differential attacks, we encrypted the Lena image using our algorithm and the scheme proposed in [11,[13][14][15][16]. We performed a 1 bit change on the original plaintext image and tested the impact on the corresponding encrypted image by calculating the values of NPCR and UACI.…”

“…At present, chaotic encryption systems are the current research hotspots, and many researchers are engaged in chaotic system related research [11][12][13]. For color image encryption, DNA sequence manipulation [14], scrambling [15], and chaotic mapping [16] are presented. These algorithms are very sensitive.Image data have much inherent feature information such as shape, color, texture, etc., and there is a correlation between image pixels.…”

With the development of multimedia technology, the secure image retrieval scheme has become a hot research topic. However, how to further improve algorithm performance in the ciphertext needs to be further explored. In this paper, we propose a secure image retrieval scheme based on a deep hash algorithm for index encryption and an improved 4-Dimensional(4-D)hyperchaotic system. The main contributions of this paper are as follows: (1) A novel secure retrieval scheme is proposed to control data transmission. (2) An improved 4-D hyperchaotic system is proposed to preserve privacy. (3) We propose an improved deep pairwise-supervised hashing (DPSH) algorithm and secure kNN to perform index encryption and propose an improved loss function to train the network model. (4) A secure access control scheme is shown, which aims to achieve secure access for users. The experimental results show that the proposed scheme has better retrieval efficiency and better security.

“…DNA encoding with permutation and chaos techniques has been used in efficient image encryption [11], [15], [30]. Both substitution and permutation components have been found in [11] to encrypt images.…”

“…Image data in [15] is transferred into a DNA sequence based on random encoding, then a self-adaptive permutation is used to generate the final cipher image. In [30], images are transformed into one-dimensional sequence, then pixels are shuffled using chaotic and DNA based permutation, afterward a DNA-diffusion process is used to generate the cipher. Efficiency and simplicity of DNA and Elliptic Curve (EC) cryptography are combined with [31].…”

Abstract: The fast and wide development in information technology and data handling has made researchers to be interested in the data confidentiality and to think about finding new and complex methods in data encryption. In this paper, a novel method for encryption is introduced. The idea beyond this proposed method is to take the advantages of the DNA computing and merged it with the concept of the classical transposition cipher by applying the random permutation in order to design this novel encryption method. The emerging DNA computing with the random numbers for transposition produced a highly complex ciphertext that make the task of cryptanalysis more sophisticated and difficult to analyze and break it.

Summary In telemedicine and e‐health system, the medical images are transmitted through telecommunication. In telecommunication, medical images are transmitted through open source networks. The hackers can tamper or add noise to medical images. Diagnosing the correct disease from the altered medical images is highly impossible. Hence indulge with security, confidentiality and integrity for medical images. In this work, heterogeneous hyper chaotic maps, deoxyribonucleic acid (DNA) cryptography and SHA‐512 is proposed in a new multilevel cryptosystem. The multilevel permutation is performed using heterogeneous chaotic map and zigzag transform. The multilevel diffusion is performed using DNA multiplication and DNA ADD operation. To verify the integrity the SHA‐512 is employed. All DNA coding, and DNA decoding rules are employed dynamically to generate the encrypted medical image. The introduced multilevel cryptosystem provide better security analysis for medical image transmission. The proposed method is implemented in MATLAB software. The performance of proposed approach is associated with existing approaches in terms of evaluating parameters like NPCR (number of pixel changing rate), UACI (unified average changed intensity), correlation coefficient and time taken in seconds. Hence it proves the performance and efficiency of the proposed method are high as compared to the existing methods. The proposed approach also improves the security level and offers integrity and confidentiality, and provide better medical image for encryption with less time complexity.
