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.

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

Chaos can be thought of as a superset of pseudo random number generators employed as a part of standard encryption algorithms and is a noteworthy and fundamental consequence of nonlinear dynamics. The important estimation of disarray is the capacity to create a wide range of different pseudo random number generating algorithms. While there are, on a fundamental level, a boundless number of chaos based algorithms that can be designed, they generally depend on the utilization of floating point arithmetic and require high precision floating point computations to produce sensibly extensive cycles. These floating point schemes are computationally intensive given that the number streams they create are generally changed into bit streams. In this context, this paper audits encryption methodologies in view of floating point algorithms.

In today's cryptographic landscape, evaluating encryption algorithms' integrity is crucial. Neural networks offer promise for extracting information from Data encryption Standard (DES) encrypted data. This report explores diverse methods of DES attacks using deep learning techniques. The primary aim is to decode DES-encrypted data with neural networks, extending this to contemporary encryption algorithms. The proposed system uses Long Short-Term Memory (LSTM) networks to improve plaintext reconstruction from DES-encrypted data. It evaluates LSTM network performance metrics and seeks to predict critical patterns. Findings reveal the neural network's impressive ability to predict plaintext with 98% accuracy after 250k training iterations. However, performance varies with the encryption key, and complete plaintext recreation remains challenging. This method also experiments using the Firefly algorithm to enhance key prediction, improving overall efficiency. Artificial Neural Networks (ANNs) for classification tasks on encrypted data show promise for practical applications. Future work can focus on enhancing classification accuracy, exploring diverse data types, and studying the critical impact on performance metrics. © 2023 IEEE.

Image encryption is a specialized subfield of cryptography, distinguished by the high correlation between neighboring pixels, which necessitates unique approaches to disrupt this correlation. While all encryption approaches fundamentally involve confusion and diffusion operators, the specific implementations of these operators can vary significantly. In recent years, approaches that combine chaos theory with optimization techniques, which aim to find the optimal solution among numerous possibilities, have become prevalent. These studies, which aim to enhance the security and efficiency of the encryption process, such as by selecting the initial values of chaotic maps in regions with high chaotic behavior, show promise. This study examines the most commonly applied optimization methods in the field of cryptography within the context of image encryption, providing a comprehensive overview. Additionally, it empirically demonstrates that the optimization techniques employed in image encryption studies improve encryption quality. © 2024 IEEE.

With the rapid development of Internet of Things (IoT) technology, interconnectivity between devices has become increasingly widespread. However, traditional IoT security measures struggle to cope with increasingly complex security threats and cannot fully exploit the advantages of interconnectivity due to the limited computational resources of the devices. To address this, we propose a blockchain-based IoT security framework comprising Wallet Component, Smart Contract Component, MultiLayer Security Component, and Common Component. This framework, designed for resource-constrained environments and embedded into cellular communication modules, enables multi-end offloading of computational tasks and secure transmission for IoT devices. Experimental results show that the data processing capability of the decentralized network architecture based on this framework is improved by 115.06% compared to traditional methods, enhances the security and autonomy of IoT devices, and significantly strengthens the degree of IoT decentralization. This provides a valuable reference for designing next-generation IoT security architectures. © 2014 IEEE.

Cryptography-Based Privacy-Preserving Method for Distributed Optimization over Time-Varying Directed Graphs with Enhanced Efficiency

In this paper, we study the privacy-preserving distributed optimization problem, aiming to prevent attackers from stealing the private information of agents. For this purpose, we propose a novel privacy-preserving algorithm based on the Advanced encryption Standard (AES), which is both secure and computationally efficient. By appropriately constructing the underlying weight matrices, our algorithm can be applied to time-varying directed networks. We show that the proposed algorithm can protect an agent's privacy if the agent has at least one honest neighbor at the initial iteration. Under the assumption that the objective function is strongly convex and Lipschitz smooth, we rigorously prove that the proposed algorithm has a linear convergence rate. Finally, the effectiveness of the proposed algorithm is demonstrated by numerical simulations of the canonical sensor fusion problem. © 2025 IEEE.
