With the rapid popularization of intelligent vehicles, the security of vehicle terminal firmware in the process of remote upgrade is becoming more and more important. To this end, two improvement measures are proposed to enhance the security of the firmware upgrading process: firstly, the key expansion in the traditional AES algorithm is improved, and a random function is used to generate the first-round key and optimize the round key expansion algorithm;secondly, a new key transmission method is proposed to enhance the security of the transmission process by using the dynamic insertion of the key technology. Experiments have shown that the combination of these two methods significantly improves the security of the firmware during the upgrade process without reducing the encryption efficiency. © 2024 IEEE.

The paper presents an optimized SIMON lightweight cryptographic algorithm that balances security, performance, and cost in contexts with limited resources. By lowering the computational cost and preserving strong security characteristics, the suggested changes make the algorithm appropriate for use in embedded systems, Internet of Things (IoT) devices, and mobile platforms. To improve encryption efficiency, changes have been made, such as fewer bit shift operations and the consolidation of bit-wise functions. A thorough evaluation process is applied to the updated algorithm, which involves calculating measures like information entropy, UACI (Unified Average Changing Intensity), and NPCR (Normalized Pixel Change Rate). Empirical findings show that the optimized SIMON algorithm significantly increases encryption efficiency and speed while maintaining the security of the algorithm. © 2024 IEEE.

In the era of edge computing, securing data transmission has become paramount, especially given the real-time requirements and limited computational resources of edge devices. This study introduces a novel Chaos Theory-Based Lightweight encryption Algorithm (CTBLEA) designed to enhance data protection in edge computing environments. The proposed algorithm leverages the inherent unpredictability of chaotic maps to secure data streams without imposing significant computational burdens. By adopting a lightweight encryption mechanism, CTBLEA ensures minimal latency and energy consumption, making it ideal for resource-constrained edge devices. Extensive experiments were conducted to evaluate the algorithm’s performance. CTBLEA achieved an encryption and decryption time of 0.25 ms per kilobyte, showing a 35% reduction in latency compared to traditional AES encryption in similar environments. Furthermore, the algorithm demonstrated an energy consumption reduction of 40% while maintaining high security standards with an average key space of 10^15, making brute-force attacks infeasible. Security tests showed a correlation coefficient close to zero (0.003) between the original and encrypted data, indicating high randomness and minimal data correlation. Additionally, the algorithm’s resistance to statistical and differential attacks was validated, with a 99.7% randomness score from the NIST suite tests. These results confirm the potential of CTBLEA for safeguarding real-time data in edge computing, offering a secure, efficient solution for next-generation IoT and edge environments. © 2024 IEEE.

Aiming at the problem of improving image security in the process of transmission line monitoring under the condition of limited computing resources, a security encryption algorithm for transmission line monitoring images is proposed. The algorithm uses the information of the image itself as the original key, realizes the secure sharing of the original key, and expands the key space. On this basis, the algorithm uses chaotic maps to perform diffusion encryption and scrambling encryption on the image. Experimental results show that the proposed algorithm can effectively resist brute force attack, brute force attack and statistical analysis attack, and can effectively improve the security of the monitoring image. It has a broad application prospect in the field of transmission line visual monitoring. © 2024 IEEE.

To ensure data security during the gateway's data uploading process, we introduce the advantages of chaotic mapping to AES. We then develop a multi-protocol encrypted gateway architecture based on an improved AES data encryption algorithm using domestic chips. To enhance the benefits of chaotic mapping, we introduce normalization based on the traditional Logistic mapping to create a new L-Logistic mapping. This expands the range of chaotic mapping. Our experiments demonstrate that the random number series generated by the L-Logistic mapping can pass the frequency and travel tests specified by NIST. The study proposes a composite chaotic AES encryption method that combines the L-Logistic mapping and Chebyshev mapping with AES encryption. This method encrypts data in groups using a single secret. The study found that the composite chaotic AES encryption has a more stable avalanche effect (65±5) compared to the result of 60±10 for AES encryption alone. © 2024 IEEE.

This paper introduces an image encryption algorithm based on 2D-Sine-Cosine chaotic mapping and compressed sensing technology. This algorithm introduces a novel 2D-Sine-Cosine chaotic mapping function. By using nested sine and cosine functions and selecting appropriate parameters, chaotic oscillators with strong randomness, wide traversal range, and complex nonlinear behavior trajectories can be generated in phase space. Combined with compressive sensing theory, image compression and encryption can be achieved. The experimental results show that the encryption algorithm proposed in this paper has good performance. © 2024 Technical Committee on Control Theory, Chinese Association of Automation.

Modular exponentiation (ME) is a mathematical operation that is used for several public-key cryptosystems (PKCs) and other applications. It is a complex task that is an essential computational tool that enables efficient handling of large numbers, especially in cryptography and computer algorithms. Its efficiency is obtained from advanced mathematical techniques like exponentiation by squaring, which is known to reduce computational complexity significantly. In this method, an efficient ME operation i.e. the modular exponentiation method is presented which improves raising any integer x to a power, namely k, and reducing the result to the modulo some integer n. This ME operation is easy to implement on paper but is expensive for resource-constrained devices in terms of the time of computation, energy consumption, etc. To tackle this problem, several different methods of computation have been proposed its implementation efficiently. In this paper, we present the implementation of an efficient ME method for single word size and then implement the method in hardware using Verilog HDL. Then, after implementation, we compare the results of the implementation of our results with two of the most frequently used conventional methods of ME i.e. Montgomery method and the Barret method. The performance parameters like clock cycles, power, and utilization are compared and presented. The low power and faster exponentiation can have potential application in emerging internet of things (IoT) and low power sensor nodes in future. © 2024 IEEE.

The traditional image encryption algorithm provides a strong security in protecting image data, and there is a situation that the encryption and decryption process consumes too much time resource computing resources, and before the image encryption operation, the algorithm adopts the LANCZOS resampling method, which can retain the details and clarity of the image to the greatest extent by using the Lanczos filter for resampling, thereby reducing the size of the picture and speeding up the encryption and decryption of the picture, Firstly, the algorithm generates three random sequences through the logistic chaotic system, uses the improved Henon chaotic system to generate the row scramble sequence and the column scramble sequence, and uses the SM4 encryption algorithm to add the hash value generated by the image pixel matrix to the end of the image ciphertext, so as to ensure that one picture and one secret can be known whether the image ciphertext information has been tampered with in the transmission process to ensure the integrity of the image. Experimental verification shows that the encryption algorithm has high security and excellent encryption performance, and can resist brute force attacks, statistical attacks and differential attacks. © 2024 Copyright held by the owner/author(s).
