Aiming at the limitation of one-dimensional Chebyshev chaotic map, an improved two-dimensional Chebyshev chaotic map is proposed. This map makes its structure more complex by extending the original one-dimensional map to a high-dimensional map and adding system parameters. Then, the introduction of the sine function further increases the computational complexity of the mapping. Aiming at the periodic shortcoming of traditional Arnold scrambling, the non-linear improvement of its scrambling equation is carried out to make it have better scrambling characteristics. Based on the improved Chebyshev map and the improved Arnold scrambling equation, a digital image encryption algorithm is proposed. Experimental results show that the proposed encryption algorithm can effectively resist plaintext attack, differential attack, statistical analysis and other attacks.

With the development of information technology, such as Big Data, O2O, Cloud Computing, the Internet of Things and Artificial Intelligence, the Hainan Rural Tourism Wisdom Management Platform should provide complete, safe and available information resources. How to make the information correctly generated, stored and transmitted has become very important. The Hainan Rural Tourism Wisdom Management Platform will use rsa encryption algorithm for data encryption to ensure data security. Because the rsa encryption algorithm is a public key encryption algorithm, if the keys are enough long, the information encrypted by rsa algorithm is unable to be cracked, which has been recommended as the public key data encryption standard by ISO.

In the present paper we will show a system to realize an innovative cryptographic code that ensures a high level of security using Information Fusion (IF) techniques. In detail, we have decided to merge two codes respectively generated by an algorithm of Cryptographic Public-key and by fractals relations. A companion IF method has been presented with a different use in [1]. Indeed, in the previous paper it was created an identification access key, while here we wish to generate a highly randomized Cryptography key to be used for encrypting. The choice of using fractals to generate numbers to be fused with codes of Public-Key Cryptography, is due to the randomness of these structures. The idea is to use these features for cryptographic applications such as One-Time-Pad. The presented new modified fusion technique, with respect to [1], is called F&NIF (Fractal & Numerical Information Fusion).

The Internet is developing rapidly, which leads to a sharp increase in information transmitted by the network. Moreover, people have a higher demand for encrypting meetings and encrypting information transmission. Currently, the data encryption technologies used in network transmission mainly include symmetric encryption algorithms, asymmetric encryption algorithms, virtual network encryption technology, SSL protocol encryption, etc. However, the widely used symmetric encryption algorithm has some problems, such as complex distribution and complicated management of keys, while the asymmetric encryption algorithm generally has the disadvantages of slow encryption and decryption speed. The research and analysis of the typical symmetric encryption algorithm DES and asymmetric encryption algorithm rsa are studied to address this issue. This paper puts forward mixed cryptogram arithmetic of DES and rsa. The principle of the algorithm is that the sender encrypts the key of DES with rsa's public key and then encrypts the plaintext with the new longer key by DES. The receiver can decrypt the encrypted key and ciphertext to obtain plaintext. The advantage of this hybrid algorithm is that rsa only needs to encrypt the short key of DES. Therefore, the encryption speed is improved greatly, and a longer new key is obtained, which makes the encryption result of DES more secure and reliable. The hybrid algorithm shows good performance through the code implementation and analysis of the results. Not only the encryption speed is fast, but the security is also guaranteed, and it has a favorable application prospect in digital signature and other fields. © 2023 IEEE.

An algorithm for substitution box (S-box) construction is proposed by using fractional-order (FO) 4D hyperchaotic system in this paper. Based on hyperchaotic sequences generated by the FO 4D hyperchaotic system, exclusive-or (XOR) operations, and permutation the S-box is constructed. A comprehensive evaluation based on various algebraic criteria demonstrates that the proposed S-box exhibits favorable performance in terms of strict avalanche criterion (SAC), differential approximation probability (DP), nonlinearity (NL), bit independence criterion (BIC), linear approximation probability (LP), fixed point (FP), reverse fixed point (FPr), and correlation immunity (CI). The proposed S-box exhibits excellent NL of 112, comparable to that of the Advanced Encryption Standard (AES) S-box. Furthermore, a novel color image encryption technique is developed to ensure the privacy of color images. The proposed color image encryption algorithm combines Arnold Cat map (ACM), a high-performance generated S-box, Rivest-Shamir-Adleman (rsa) algorithm with 2D Henon chaotic map (HCM). Through rigorous testing, analysis, and comparison with recently reported image encryption algorithms, the suggested algorithm demonstrates its security, efficiency, and resistance to different standard attacks. Notably, the suggested algorithm for color image encryption offers a substantial key space and achieves an approximate correlation of 0 between adjacent pixels. Additionally, the entropy approaches the ideal value of 8.

Recent innovations in cloud computing and the Internet of Things (IoT) have reshaped numerous real-time applications. However, the exchange of sensitive information within these systems requires strong security measures to ensure privacy, confidentiality, and integrity. In the Internet of Vehicles (IoV), which connects vehicles to each other and to servers, securing communication is critical for maintaining system performance and safety. The proposed model tackles these challenges by integrating cryptography and steganography, offering a multi-layered security solution for information exchange in the IoV network. In the proposed model, secret messages are initially encrypted using the Improved rsa (Irsa) technique, followed by a binary reversal of the encrypted data. The Pixel Value Difference (PVD) technique, enhanced with the Pixel Indicator Technique (PIT), is then employed to embed these reversed binary bits into the cover image. This process ensures the security of the hidden data while preserving the quality of the image. Performance evaluations show that the model achieves excellent image imperceptibility after embedding, as evidenced by improved PSNR and SSIM values. It also exhibits strong resistance to various complex attacks, while achieving an average embedding capacity of 3.98 bits per pixel (bpp). Extensive testing confirms the model's effectiveness in preventing steganalysis attempts, making it a reliable solution for secure data hiding in IoV networks. This innovative method safeguards sensitive data's privacy and integrity without compromising system performance.

A Study of Cryptographic algorithms on Special Linear Group Over Ring of Integers Modulo m

Despite the development of numerous cryptographic algorithms over the last decade to ensure greater security for the users, the cyberattack forms are still advancing, which creates a challenge for the research community to build more efficient infrastructure. It motivates us to design more advanced algorithms based on a set of matrices that form a group under matrix multiplication, meaning they satisfy the group axioms of closure, associativity, identity, and irreversibility. Specifically, this study explores the application of three cryptographic algorithms on a special linear group of matrices over a ring of integers modulo m. The first algorithm relies on the rsa key exchange algorithm, which we modify to a special linear group. The second is an asymmetric rsa variant of a cryptographic algorithm defined on the co-adjoint orbit of element K belonging to a special linear group. All matrices from the orbit of matrix K have the same order and can be easily encrypted and decrypted by a pair of secret asymmetric cryptographic keys. We apply the Kronecker product of non-Abelian groups to construct an energy-efficient cryptographic algorithm with possible application on sensor networks. Due to the multiplicative property of the Kronecker product, both the encryption and decryption can be performed in parallel over the matrices of low degree. The third one is another rsa variant of a symmetric cryptographic algorithm, which can be encoded with a special linear group to significantly increase its complexity at the stage of non-negative matrix factorization. To encrypt a given set of numbers, we write it in a matrix form with a secret sequence of generators. As a result, the decryption relies on solving a simple system of nonlinear equations. Security of the algorithm lies in its complexity, aimed at building a correct sequence of generators necessary for encryption.
