In an era where data security is paramount, this research presents MathCrypt, a novel symmetric encryption-decryption algorithm designed to address vulnerabilities in traditional cryptographic methods. Unlike conventional approaches, MathCrypt leverages numerical root-finding methods combined with the Diffie-Hellman algorithm to enhance security and computational efficiency. By integrating the Bisection, Newton-Raphson, and Secant methods into the encryption process, MathCrypt ensures robust protection against reverse-engineering attacks while maintaining scalability for large datasets. Performance evaluations demonstrate that iterative methods like Secant and Newton-Raphson significantly reduce encryption times compared to conventional approaches. This paper provides a detailed analysis of the proposed algorithm, comparing numerical techniques, and showcasing its potential for real-world cryptographic applications. The findings underline the feasibility and effectiveness of MathCrypt, paving the way for further advancements in secure communication systems. © 2025 IEEE.

In this paper, we have discussed isogeny-based cryptography as a rather appealing option for post-quantum security. We provide analysis of current protocols like SIDH (Supersingular Isogeny Diffie-Hellman) and SIKE (Supersingular Isogeny Key Encapsulation) setting up fundamental issues with their security and performance. In this work we introduce a novel isogeny pathfinding algorithm that employs graph theory as well as probabilistic models in order to lower its computational complexity. The results show significant improvement in both efficiency and security, strengthening the case for the use of isogeny based systems in a quantum-resilient cryptographic space. © 2025 IEEE.

Code-based cryptography is based on the difficulty of the syndrome decoding problem (SDP) and is one of the promising candidates for post-quantum cryptography. Information set decoding (ISD) is known as one of the most efficient frameworks for solving SDP. There has been some work analyzing the time complexity of ISD in the situation where the amount of memory consumption is limited. In this work, we propose a new variant of the Both-May algorithm which is known as the fastest ISD. The proposed algorithm achieves more efficient asymptotic time-memory trade-offs compared with the original Both-May algorithm and existing time-memory trade-off versions of other ISDs. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

With the advent of the era of big data and 5G communications' massive data, high-speed cryptographic algorithms are in demand. This paper proposes a new fast implementation of the Advanced encryption Standard (AES) algorithm based on graphics processing unit(GPU) and fixed slicing technology. Based on the structural features of AES, the algorithm's performance can be improved by fixing certain slices of AES and adjusting its linear layer on compute unified device architecture(CUDA). By further adopting full-bit fixed and half-bit fixed implementations of AES, it was found that the time and data throughput of the two methods were similar, but the half-bit fixed implementation used fewer operands. The research results show that the application of fixed slice technology can improve the performance of the AES algorithm and enhance its spatial utilization. Applying the fixed slice technology to implement the AES algorithm can achieve a 2.60-fold and 5.88-fold performance improvement on CPU and GPU, respectively, with the peak acceleration ratio on GPU reaching 310. Compared with existing AES parallel algorithms, the implementation results of this paper have the highest performance improvement of 21.6 times. In summary, GPU and slicing technology can significantly enhance the performance of symmetric cryptography. © 2025 SPIE.

Randomness is key to many of the protocols used in cryptography, various math algorithms, and communications. However, while it is widely used it is not well understood due to its mathematical nature and foundations. Most users would prefer to just be able to access random numbers and have them readily available for use rather than designing and implementing those functions. One of the suggested sources of randomness is the traffic found on a network. However, there are no studies that verify the veracity of the randomness of that data. Further, randomness may vary by the type of network to which the node is attached. It could also vary by the composition of the nodes attached to the network and the users of those endpoints. To settle the question of whether or not the internet can, or should, be used as a source of randomness a survey and statistical analysis of the resulting collected data are done. © 2025 IEEE.

The appearance of the terminal system of electric power Internet of Things has brought a lot of convenience to the electric power industry, but at the same time it is also facing increasingly severe network security challenges. In order to ensure the safety and confidentiality of power data, it is necessary to adopt high-intensity encryption technology. However, lightweight cryptography has attracted wide attention because of its smaller and more efficient features. The purpose of this experiment is to verify the application effect of lightweight cryptography technology in power IOT terminal system. Ten IOT terminal devices are selected, and their encryption and decryption tests are carried out under the condition that they adopt traditional encryption algorithm and lightweight encryption algorithm. The results show that the lightweight cryptography technology has faster encryption and decryption rate and shorter encryption and decryption time, and has better application performance in the terminal system of power IOT. In addition, some strategies such as strengthening the standardization and normalization of lightweight cryptography, strengthening its attack testing, and establishing a perfect application management and monitoring mechanism are put forward to ensure the security and stability of lightweight cryptography in the terminal system of electric power IOT. Specifically, the average encryption and decryption time of lightweight cryptography is 6.6 ms and 6.7 ms, and the average encryption and decryption rates are 155.2 Mbps and 149.3 Mbps, respectively, while the average encryption and decryption time of traditional algorithms is 7.0 ms and 7.0 ms, and the average encryption and decryption rates are 146.7 Mbps and 139.4 Mbps, respectively. It shows that the lightweight cryptography technology performs better than the traditional algorithm in the terminal system of power IOT. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025

We proposed methodology that enables users to encrypt text messages for secure transmission over cellular networks. This approach utilizes the AES algorithm following the proposed protocols for encryption and decryption, ensuring fast and reliable data protection. This approach ensures secure text encryption and enables users to enter messages that are encrypted using a key at the sender's end and decrypted at the recipient's end, which is compatible with any Android device. SMS are encrypted with the AES algorithm, making them resistant to brute-force attempts. As SMS has become a popular form of communication, protecting personal data, email alerts, banking details, and transactions information. It addresses security concerns by encrypting messages using AES and cryptographic techniques, providing an effective solution for protecting sensitive data during SMS exchanges.

Novel 2D nonlinear sine-log-sqrt-logistic map and staircase block scrambling for a rapid image encryption algorithm

引用

Journal of Information Security and Applications 2025年 92卷

作者： Wang, Meng-meng Jin, Shun-wen Wang, Hongxia Xu, Man-tao Liu, Si-hang School of Information and Control Engineering Qingdao University of Technology Qingdao266033 China College of Information Technology Shanghai Jian Qiao University Co Ltd Shanghai201315 China School of Intelligent Manufacturing Jiangxi Science and Technology Normal University Nanchang330038 China

In this paper, we propose a nonlinear 2-dimensional hyperchaotic map, called the 2D nonlinear sine-log-sqrt-logistic map (2D-NSLSLM), which introduces both the logarithmic function and the square root function. By incorporating the square root and logarithmic functions, the complexity of its nonlinear characteristics is further enhanced. This increases the dynamic complexity of the system and makes the system difficult to predict. Compared to some 2D chaotic maps, the 2D-NSLSLM exhibits higher sensitivity, a wider chaotic range, and more complex chaotic behavior. To explore its applications, 2D-NSLSLM is applied to formulate an image encryption algorithm with a new structure. The proposed algorithm consists of three steps: three rounds of staircase block scrambling, followed by one round of fast diffusion, and concluding with an additional round of staircase block scrambling. The simulation experiments prove that the structure not only has good anti-multiple-noise attacks and anti-differential attack ability, that is, it cleverly balances the robustness and anti-different attack ability, but also greatly improves the encryption speed. Through experiments and comparisons involving local Shannon entropy, information entropy, chosen plaintext attacks, and differential attacks, the results indicate that the new algorithm provides very secure encryption. © 2025
