This article presents a novel 2-layer image encryption cryptosystem and transmission protocol designed for secure communication of military reconnaissance images over unmanned aerial vehicle (UAV)-assisted relaying networks. The proposed scheme aims to address the growing need for robust, secure, and efficient transmission of sensitive imagery data across wireless ad-hoc networks, often characterized by unpredictable and hostile environments. The first layer of the proposed cryptosystem employs a Genetic Algorithm (GA) utilizing a Mersenne Twister (MT) key, providing a robust framework for initial image encryption. The second layer further leverages security by employing dna coding, that is also driven by a MT key. The encrypted images are subsequently transformed into a one-dimensional bit-stream, ready for transmission. The bit-stream is then channel coded using either a convolutional code or a low-density parity-check (LDPC) code, offering flexibility based on the specific network conditions and requirements. The coded data is then BPSK-modulated and transmitted over a multi-hop wireless relay network, with relays mounted on freely-moving UAVs. This scheme optimizes for both security and transmission efficiency, critical for the time-sensitive and mission-critical nature of military operations. Extensive performance evaluation is carried out, presenting bit error rate (BER) curves and various image encryption metrics, demonstrating the robustness, reliability, and security of the proposed scheme. This contribution is expected to significantly enhance the secure communication of military reconnaissance images, paving the way for more advanced, secure, and efficient communication systems in the military sector.

The integrity and authenticity of the message, and it's nonrepudiation, are provided by digital signatures. We introduce quantum digital signature schemes based on Quantum Dots, where dna coding is used to increase the intricacy of phase space. We attain the optimal security standard by constructing a deterministic dynamic system in a finite phase space with n points and by using symbolic dynamics. Also, given the chaotic Substitution box(S-box), a confusing step has been added for greater security. The introduced quantum dynamical map is used to create procedures to resistance again the common attacks in the digital signature such as non-repudiation, unforgeability, and transferability. Its security depends on the length of the signature, directly.

The current algorithm of encrypting images uses low-dimensional chaotic systems with a limited key space and poor security, while high-dimensional chaotic systems are difficult to implement and inefficient. Additionally, if image encryption algorithms use fixed dna encoding rules, they could be cracked;dynamic coding can easily deviate from optimal solutions, thus causing algorithm instability. Based on this, a novel technique for image encryption is presented in this article. It is possible to avoid linear correlation of the chaotic sequence by randomly jumping on two uncorrelated one-dimensional chaoses. Meanwhile, numerous encryption results are generated in parallel by randomly grouping dna encoding groups and encoding operations, and the optimal solution is then selected based on the encryption results, thereby minimizing ciphertext image instability to some extent. According to the experimental results, this algorithm produces high-security, plaintext-sensitive, and non-cracking encrypted images. Furthermore, this algorithm produces excellent encryption results both on color and sized images, and is applicable to a wide variety of applications.

Security issues of digital images have rapidly become a frontier research focus in the past decades. When a chaotic system is applied to encrypt image, it usually requires large parameter space, high ergodicity and easy implementation. In this paper, taking Sine and ICMIC map as seed maps, a novel 2D hyperchaotic Logistic map (2D-SILM) is designed based on the 2D parameter modulation model (PMM). Its dynamics are analyzed by means of attractor diagrams, Lyapunov exponent spectrum (LEs) and complexity diagrams. The results along with NIST SP-800 test prove the feasibility of 2D-SILM. Based on 2D-SILM and dna coding, a reliable image encryption scheme is proposed with two-round improved permutation-confusion-diffusion operations. SHA-512 function is introduced in the generation of the secret key. After applying the effective permutation process called chaotic grouping shuffle (CGS) on pixels position, dna sequences procedures varied from different rounds are used to confuse the image pixels value. Finally, a novel diffusion method containing row and column operation is designed. Simulation results of some indexes validate the security and efficiency of the proposed algorithm. It also shows better resistance to typical attacks.

With advances in modern technology, the security of information, including the protection of digital images, is of particular interest. Due to the type of special storage format of images and the fateful dimension of 1D map that have a small secret key space, in this paper, a joint-based encryption technique on the pseudo-random and sophisticated character of hyperchaotic behavior and dna coding is proposed. The entire dynamics of a financial hyperchaotic system is studied for a better selection of the sequence key using nonlinear analysis tools. A rich dynamic of this analysis reveals a plethora of phenomena such as multistability and offset boosting, which, to our knowledge, have not yet been the subject of a study on financial hyperchaotic systems. The set consisting of the pseudo-random aspect of the financial hyperchaotic system used in all stages of encryption, dna coding (algebraic operations, complementation, and dna rules), and the scrambling of the positions of each image pixel is exploited to reinforce the effectiveness of the confusion and diffusion of digital images. To analyze the security and robustness of the proposed algorithm, some security tests such as histogram analysis, correlation, information entropy, as well as key analysis are carried out. The values of correlation coefficients of the encrypted images using the proposed scheme are close to zero, The entropy values of the test images are overall greater than 7.99 and the key space of the is greater than 2(100). Besides, differential analysis shows that the number of pixel change rate (NPCR) and unified average change intensity (UACI) for the proposed technique are greater than 99.50% and 30%, respectively. Furthermore, the quantitative analyses of occlusion and data loss attacks as well as the results of comparison with some advanced algorithms show the efficiency and security of the proposed cryptosystem.

In this paper, a color image encryption algorithm based on dna encoding combined with logistic map and spatial map is proposed. Firstly, the algorithm carries out scrambling by logistic map for R, G, B channels. Then, XOR is operated between channels pixel and sequence matrix controlled by spatial map. After that, realizes the addition of R, G, B by dna addition after dna encoding and carries out complement operation by using the dna sequence matrix controlled by spatial map. What is more, R G B channel images are got after dna decoding. Finally, gets the encrypted R, G, B images by reconstructing R, G, B components. The results of several experimental, statistical analysis and key sensitivity tests show that the proposed image encryption algorithm provides an efficient and secure way for real-time image encryption and transmission.

This paper proposes a novel confusion and diffusion method for image encryption. One innovation is to confuse the pixels by transforming the nucleotide into its base pair for random times, the other is to generate the new keys according to the plain image and the common keys, which can make the initial conditions of the chaotic maps change automatically in every encryption process. For any size of the original grayscale image, after being permuted the rows and columns respectively by the arrays generated by piecewise linear chaotic map (PWLCM), each pixel of the original image is encoded into four nucleotides by the deoxyribonucleic acid (dna) coding, then each nucleotide is transformed into its base pair for random time(s) using the complementary rule, the times is generated by Chebyshev maps. Experiment results and security analysis show that the scheme can not only achieve good encryption result, but also the key space is large enough to resist against common attacks.

This paper proposes a new encryption scheme for color images based on Deoxyribonucleic acid (dna) sequence operations and multiple improved one-dimensional (1D) chaotic systems with excellent performance. Firstly, the key streams are generated from three improved 1D chaotic systems by using the secret keys and the plain-image. Transform randomly the key streams and the plain-image into the dna matrices by the dna encoding rules, respectively. Secondly, perform the dna complementary and XOR operations on the dna matrices to get the scrambled dna matrices. Thirdly, decompose equally the scrambled dna matrices into blocks and shuffle these blocks randomly. Finally, implement the dna XOR and addition operations on the dna matrices obtained from the previous step and the key streams, and then convert the encrypted dna matrices into the cipher-image by the dna decoding rules. Experimental results and security analysis show that the proposed encryption scheme has a good encryption effect and high security. Moreover, it has a strong robustness for the common image processing operations and geometric attack. (C) 2015 Elsevier B.V. All rights reserved.

In this work, an audio encryption framework is proposed based on the chaos theory and dna encoding. Traditional encryption algorithms designed for text data might not be efficient for handling the bulk data of audio files, leading to slow processing times and increased storage requirements. Striking the right balance between robust encryption and efficient processing is crucial. Additionally, some encryption methods can introduce noise or artifacts into the audio signal, impacting its clarity. Maintaining high-fidelity audio quality while ensuring strong encryption remains an ongoing area of research. Despite these challenges, the need for secure audio communication is undeniable. The RCM chaotic map is used to introduce chaotic properties in the encryption framework. A novel pseudorandom bit generator approach is proposed and used for encryption purposes. The proposed work is a symmetric encryption approach and is completely lossless. The proposed approach uses some lightweight computational procedures that make the algorithm simple and computationally less expensive which makes it suitable for real-time applications. Furthermore, the proposed approach shows significant performance and resilience against various cryptographic attacks. A new scrambling algorithm is proposed to add a layer of security. The proposed scramble algorithm uses logistic map beside the RCM map. The proposed approach achieved 98.28 % NSCR value and 33.63 % UACI values on average. The experimental outcomes are encouraging for practical applications of the proposed approach.

Recently, an image fusion encryption algorithm [Optik 124 (18) (2013) 3596-3600] was proposed based on dna sequence operation and hyper-chaotic system. The security of this algorithm depends mainly on both five keys as the initial conditions of hyper-chaotic system and a key image. In this paper, we cryptanalyze the algorithm and find that two chaotic keystream determined by the five keys keep unchanged for different image encryption processes. The two chaotic keystream can be revealed and the computational complexity is approximately O(mn), where m and n represent the height and width, respectively. In addition, the key image needs to be changed for each encryption. Finally, experimental results also verify our idea. 2013 Elsevier GmbH. All rights reserved.
