Within this article, a method of symmetric encryption of information based on a hierarchical residue number system has been developed. The corresponding mathematical and algorithmic framework is presented. The proposed approach simplifies hardware implementation and enhances operational speed by reducing modulus sizes and consequently numerical operands at each subsequent level, as well as by parallelizing computational processes. Utilizing this encryption method enables the creation of reliable, efficient, and resistant-to-cryptanalysis systems for protecting information streams. A encryption/decryption scheme and an application example of the method are provided. © 2024 IEEE.

Advanced encryption Standard (AES) is one of the most widely used cipher for data encryption. However, recent studies have pointed out some weaknesses in the subkeys used in AES. Also, the sequential subkeys generation process of AES seems to be inefficient for resource-constrained IoT devices. Therefore, in this paper, we studied how secure and efficient the Secure Hash Algorithm-3 (SHA3) generated subkeys will be for the encryption of IoT data by just replacing the AES subkeys with it. For this purpose we used the statistical test suite provided by the National Institute of Standards and Technology and found that SHA-3 generated subkeys are highly random, and also it is significantly efficient for encrypting the IoT Data. However, as symmetric keys are repeatedly used, therefore, only upto 2 MB data, the encryption is significantly (∼ 1300 times) efficient. From the experimental analysis, we find that SEASHA3 generates subkeys that are random, non-linear, and irreversible, making it more secure and efficient than traditional AES subkey generation. © 2024 IEEE.

In the past decades cryptography and specifically encryption schemes were vastly researched. This is due to the developments in technology, communication, and the rising needs to use better, more resilient encryption for different types of attacks, that are getting more sophisticated and use much more computational power than before. For these encryption schemes, there is usually a use of mathematical computation, and different problems that are hard to solve, thus creating stronger schemes. There has been a use also in different classical problems of mathematics like computing prime numbers, using elliptic curves and lattices. In this paper we suggest a novel safe encryption scheme, that is based on a formula for manufacturing Pythagorean triplets (where both perpendiculars and hypotenuse are integers). We present the decryption and encryption formulas along with several examples of their operation and encoding results we achieved with the algorithm. © 2024 IEEE.

With the development of the internet, social software and media have become ubiquitous, making images increasingly important in daily life. The dissemination of a large number of images on social networks has made information security issues increasingly prominent, and image encryption technology has become increasingly important. This article mainly studies image encryption algorithms based on chaotic systems. Firstly, the background and history of image encryption were introduced, followed by an explanation of the basic concepts based on chaotic systems. Then, several chaos based image encryption schemes were comprehensively compared, and their advantages and disadvantages were analyzed. Subsequently, several common measures for evaluating the effectiveness of encryption schemes were introduced. Finally, the future development of image encryption algorithms based on chaotic systems is discussed. ©2024 IEEE.

With the rapid development in the field of quantum computing, the security of traditional encryption algorithms is facing serious challenges. And quantum key distribution (QKD) provides a new way to solve the key distribution problem, and QKD protocol has become a new hotspot of encryption technology. This research makes a breakthrough in optimizing and applying the unstructured QKD security proof model, which is not only applicable to a variety of QKD protocols, but also dramatically reduces the dependence on mathematical skills for solving the security key. By replacing the original classical optimization solver with a VQE optimization solver based on the BFGS algorithm, this research successfully improves the processing efficiency, simplifies the pairwise constraints, and optimizes the key rate optimization solving algorithm. In practical applications, it successfully implements the secure key rate computation and solving for the QKD protocol BB84 without security vulnerability, the measurement device independent QKD protocol, and the QKD protocol BB84 under laser seed attack. Through these application cases, this project not only verifies the wide applicability of the model, but also significantly improves the computation speed and the accuracy of key rate estimation by improving the key components in the model. © 2024 IEEE.

The applications of digital images is widespread in various fields such as medical diagnosis, film production, intelligent transportation, security monitoring, virtual reality and computer vision. The security of image transmission is a widely discussed topic, and ensuring the protection of digital images has become a focal point in Internet security communication. The selection of an algorithm with strong encryption performance holds significant theoretical and practical importance for image transmission. This paper takes the pseudo-random sequence as a starting point and primarily utilizes scrambling operations, the Mersenne rotation algorithm, and operations based on chaotic sequences to explore image encryption algorithms. Firstly, it introduces the encryption principles of these three methods, followed by respective application cases and implementation using MATLAB software. Pseudo-random sequences are employed as tools in all three methods, reo rdering pixel positions according to their order in the pseudo-random sequence during scrambling operation. In the Mersenne rotation algorithm, pseudo-random sequences are used to generate random number seeds. Chaotic sequences are utilized in combination with scrambling operations to achieve image encryption through generating pseudo-random sequences. Finally, after analyzing information entropy, histograms, encryption/decryption times, and adjacent pixel correlations, we select the optimal image encryption algorithm that provides better digital image encryption effects and higher security levels for each application case along with code implementations. © 2024 The Authors.

In this modern era, the exchange of information through the internet happens almost constantly. The security of this exchanged information is crucial to prevent unauthorized parties from misusing it. One frequently exchanged form of information is files. In this research, we employed the Elliptic Curve Diffie-Hellman and chaotic map function algorithms to secure files. The results of this study indicate that the Elliptic Curve Diffie-Hellman and chaotic map function algorithms can be used to secure files in the form of text, image, audio, and video by performing file encryption and decryption. We also compared the encryption and decryption times and the resistance level against attacks with methods used by previous researchers. The comparative results show that our method has faster encryption and decryption times, as well as a higher level of resilience. Using the fastest attack method, the Baby-Step, Giant-Step, the author's algorithm demonstrates a resistance level of approximately 2.16× 1011 % greater than Heru et al.'s [7] algorithm. © 2024 The Authors.

Due to the large amount of computation required for authentication and matching in the data sharing phase, there is a certain delay in the real-time performance of the corresponding efficiency. Therefore, this paper proposes the research on the security sharing method of big data based on ECC encryption algorithm and casual transmission. After encrypting the shared data by using the point operation and group algorithm in ECC pairing, a digital signature for the shared data is designed;OT (3-out-of-l OT) mechanism is introduced into the sharing protocol to realize the matching of wildcard patterns between two security parties. In the test results, the increase in attribute vector length did not have a significant impact on the computational cost of the data sharing stage. The specific computational cost remained stable within 2.0 ∗ 103 byts, and the sharing time was within 35.0ms. Compared with the control group, it had a significant advantage. © 2024 IEEE.

Ransomware uses symmetric encryption algorithms to lock user files to extort money. This paper proposes a cryptographic algorithm loop identification method based on bit-precise execution, aiming to solve the problem of identifying unknown loops. The structure of the loop body of encryption algorithms is fixed and usually includes nonlinear operations and linear operations. This article converts the loop body in the unknown software into a set of Boolean formulas, and converts the malware into a register data flow through the symbolic executor, thereby converting it into a set of Boolean formulas for execution. Execute known encryption algorithms with bit accuracy and establish a Boolean formula input-output relationship library for cryptographic components. The two sets of Boolean formulas are passed through a designed input matrix to achieve the Boolean formula mapping and input variable mapping of the confirmation algorithm, which can effectively judge the encryption algorithms in some malware. © 2024 IEEE.
