Resilient substitution boxes (S-boxes) with high non-linearity are important cryptographic primitives in the design of certain encryption algorithms. There are several trade-offs between the most important cryptographic parameters and their simultaneous optimisation is regarded as a difficult task. In this study, the authors provide a construction technique to obtain resilient S-boxes with so-called strictly almost optimal non-linearity for a larger number of output bits m than previously known. This is the first time that the non-linearity bound 2(n-1) - 2(n/2) of resilient (n, m) S-boxes, where n and m denote the number of the input and output bits, respectively, has been exceeded for m >[n/4]. Thus, resilient S-boxes with extremely high non-linearity and a larger output space compared with other design methods have been obtained.

Security and privacy of the Internet of Things (IoT) systems are critical challenges in many data-sensitive applications. The IoT systems are constrained in terms of execution time, flexibility and computational resources. In recent years, many encryption algorithms have been proposed to provide the security of IoT communication. In this study, flexible and high-throughput hardware structures of the PRESENT, SIMON, and LED lightweight block ciphers are presented for IoT applications. The proposed flexible structures can perform various configurations of these block ciphers to support variable key sizes. For example, the PRESENT, SIMON, and LED ciphers support key sizes (80, 128 bits), (96, 144, 128, 192, and 256 bits), and (64, 128 bits), respectively. Therefore, these architectures provide versatile implementations that enable adaptive security level using a variable key size. In the proposed structures, sub-blocks of the ciphers are implemented based on optimised circuits. In the PRESENT and LED ciphers, the S-boxes are implemented based on area-optimised logic circuits. The implementation results of proposed flexible architectures are achieved in 180 nm CMOS technology. Area, throughput and throughput/area of the proposed structures have improved compared to other related works.

Diagnostic radiology is a core and integral part of modern medicine, paving ways for the primary care physicians in the disease diagnoses, treatments and therapy managements. Obviously, all recent standard healthcare procedures have immensely benefitted from the contemporary information technology revolutions, apparently revolutionizing those approaches to acquiring, storing and sharing of diagnostic data for efficient and timely diagnosis of diseases. Connected health network was introduced as an alternative to the ageing traditional concept in healthcare system, improving hospital-physician connectivity and clinical collaborations. Undoubtedly, the modern medicinal approach has drastically improved healthcare but at the expense of high computational cost and possible breach of diagnosis privacy. Consequently, a number of cryptographical techniques are recently being applied to clinical applications, but the challenges of not being able to successfully encrypt both the image and the textual data persist. Furthermore, processing time of encryption-decryption of medical datasets, within a considerable lower computational cost without jeopardizing the required security strength of the encryption algorithm, still remains as an outstanding issue. This study proposes a secured radiology-diagnostic data framework for connected health network using high-performance GPU-accelerated Advanced encryption Standard. The study was evaluated with radiology image datasets consisting of brain MR and CT datasets obtained from the department of Surgery, University of North Carolina, USA, and the Swedish National Infrastructure for Computing. Sample patients' notes from the University of North Carolina, School of medicine at Chapel Hill were also used to evaluate the framework for its strength in encrypting-decrypting textual data in the form of medical report. Significantly, the framework is not only able to accurately encrypt and decrypt medical image datasets, but it also successful

A Blockchain Technology: Analysis of a Secure Payment Mode for Enterprise E-Commerce Import and Export Trade

引用

International Journal of Network Security 2024年第5期26卷 861-866页

作者： Dong, Xianfeng Li, Jing Henan Mechanical & Electrical Vocational College Henan Zhengzhou451151 China

This paper briefly introduces the payment mode of e-commerce import and export trade based on blockchain. In this mode, the blockchain is utilized to store transaction information, while the Bresson, Catalano, and Pointcheval (BCP) encryption algorithm is employed to encrypt the transaction amount. Additionally, the additive homomorphism of the algorithm is utilized to aid in storing and validating the blockchain. Subsequently, simulation experiments were conducted in a laboratory. The results demonstrated that this payment mode enabled the successful uploading of normal transaction information onto the blockchain while effectively safeguarding the privacy of the transaction amount. It was observed that the receiver exhibited the highest efficiency in processing transaction information, whereas the initiator exhibited the lowest efficiency. Moreover, this mode effectively resisted violent decryption attempts by third parties. © (2024), (International Journal of Network Security). All rights reserved.

Image encryption algorithm based on hyperchaotic system and dynamic DNA encoding

Since the existing DNA encryption algorithms only have fixed DNA coding and decoding rules and a single algorithm that cannot meet more complex and more secure encryption requirements, an image encryption algorithm based on hyperchaotic system and dynamic DNA coding is proposed. The algorithm proposes two new operation methods in the DNA operation rules, namely the equal-additive column transformation and the equal-subtractive column transformation. which combine the SHA-256 function and the external key to generate the initial value of the chaotic system to ensure that key and plaintext of algorithm are correlated. In the encryption process, the plaintext image is firstly converted into a two-dimensional matrix for rotation and scrambling. Then the chaotic sequence generated by the hyperchaotic Chen system is used to perform DNA dynamic encoding, decoding and operation on the scrambled matrix and block matrix generated by logistic chaotic sequence. Finally, the encrypted matrix is scrambled in one dimension. Simulation results show that the improved encryption algorithm has a larger key space, breaks the strong correlation between image pixel layers, and can effectively resist multiple attacks.

The security of multimedia data and its applications has become a building block of any digital communication technology. The extensive use of multimedia content over wireless networks makes the applications exposed to different types of network attacks. Cryptography is the main technology that provides security and confidentiality to prevent unauthorised data access. A suitable design of an encryption system must be chosen to fully secure and maintain the privacy of data. On the other hand, the large size of data will be the prominent issue. In order to maintain a better performance of Internet of Things (IoT) applications, an appropriate compressionencryption scheme has to be used to ensure a secure and fast scheme without increasing the cryptosystem complexity to achieve a large encryption capacity. Therefore, this presents a hybrid scheme of H.264/MVC compression procedure and an encryption process of Latin Square Cipher (LSC) using symmetric keys. The Latin square whitening and Latin square substitution and permutation operations are included in the encryption algorithm. The simulation results and analysis of different RGB video frames using MATLAB show that the proposed scheme achieves high protection, integrity, and security performance for different transmitted video frames, high robustness performance against different network attacks, and high-security accomplishment compared to the state-of-the-art algorithms.

Cloud Communication Environment is an internet-based computing, where shared resources, software, and information are provided with computers and devices on-demand. They guarantee a way to share distributed resources and services that belong to different organizations. In order to develop cloud computing applications, security and trust to share data through distributed resources must be assured. This paper offers a study of the different mechanisms used in open cloud environments such as keys generation and management, and encryption/decryption algorithms. In addition, the paper proposes a new cryptographic environment, annotated as "CCCE" that deploys the combination between quantum key distribution mechanisms (QKD) and advanced encryption standard (AES), and demonstrates how quantum mechanics can be applied to improve computation.
