    Yi-Bo Cao1,*, Xiu-Bo Chen1, Yun-Feng He2, Lu-Xi Liu2, Yin-Mei Che2, Xiao Wang2, Ke Xiao3, Gang Xu3, Si-Yi Chen1

    CMC-Computers, Materials & Continua, Vol.78, No.2, pp. 2813-2827, 2024, DOI:10.32604/cmc.2024.046816

    Abstract Due to the rapid advancements in network technology, blockchain is being employed for distributed data storage. In the Internet of Things (IoT) scenario, different participants manage multiple blockchains located in different trust domains, which has resulted in the extensive development of cross-domain authentication techniques. However, the emergence of many attackers equipped with quantum computers has the potential to launch quantum computing attacks against cross-domain authentication schemes based on traditional cryptography, posing a significant security threat. In response to the aforementioned challenges, our paper demonstrates a post-quantum cross-domain identity authentication scheme to negotiate the session key used in the cross-chain asset… More >

    Hybrid Dynamic Optimization for Multilevel Security System in Disseminating Confidential Information

    Shahina Anwarul1, Sunil Kumar2, Ashok Bhansali3, Hammam Alshazly4,*, Hany S. Hussein5,6

    Computer Systems Science and Engineering, Vol.47, No.3, pp. 3145-3163, 2023, DOI:10.32604/csse.2023.041061

    Abstract Security systems are the need of the hour to protect data from unauthorized access. The dissemination of confidential information over the public network requires a high level of security. The security approach such as steganography ensures confidentiality, authentication, integrity, and non-repudiation. Steganography helps in hiding the secret data inside the cover media so that the attacker can be confused during the transmission process of secret data between sender and receiver. Therefore, we present an efficient hybrid security model that provides multifold security assurance. To this end, a rectified Advanced Encryption Standard (AES) algorithm is proposed to overcome the problems existing… More >

    CeTrivium: A Stream Cipher Based on Cellular Automata for Securing Real-Time Multimedia Transmission

    Osama S. Younes1,2,*, Abdulmohsen Alharbi1, Ali Yasseen1, Faisal Alshareef1, Faisal Albalawi1, Umar A. Albalawi1,3

    Computer Systems Science and Engineering, Vol.47, No.3, pp. 2895-2920, 2023, DOI:10.32604/csse.2023.040162

    Abstract Due to their significant correlation and redundancy, conventional block cipher cryptosystems are not efficient in encrypting multimedia data. Stream ciphers based on Cellular Automata (CA) can provide a more effective solution. The CA have recently gained recognition as a robust cryptographic primitive, being used as pseudorandom number generators in hash functions, block ciphers and stream ciphers. CA have the ability to perform parallel transformations, resulting in high throughput performance. Additionally, they exhibit a natural tendency to resist fault attacks. Few stream cipher schemes based on CA have been proposed in the literature. Though, their encryption/decryption throughput is relatively low, which… More >

    Efficient Technique for Image Cryptography Using Sudoku Keys

    M. A. P. Manimekalai1, M. Karthikeyan1, I. Thusnavis Bella Mary1, K. Martin Sagayam1, Ahmed A Elngar2, Unai Fernandez-Gamiz3, Hatıra Günerhan4,*

    CMC-Computers, Materials & Continua, Vol.77, No.1, pp. 1325-1353, 2023, DOI:10.32604/cmc.2023.035856

    Abstract This paper proposes a cryptographic technique on images based on the Sudoku solution. Sudoku is a number puzzle, which needs applying defined protocols and filling the empty boxes with numbers. Given a small size of numbers as input, solving the sudoku puzzle yields an expanded big size of numbers, which can be used as a key for the Encryption/Decryption of images. In this way, the given small size of numbers can be stored as the prime key, which means the key is compact. A prime key clue in the sudoku puzzle always leads to only one solution, which means the… More >

    Enhancing the Trustworthiness of 6G Based on Trusted Multi-Cloud Infrastructure: A Practice of Cryptography Approach

    Mingxing Zhou1,2, Peng Xiao3, Qixu Wang1,2,*, Shuhua Ruan1,2, Xingshu Chen1,2, Menglong Yang4

    CMES-Computer Modeling in Engineering & Sciences, Vol.138, No.1, pp. 957-979, 2024, DOI:10.32604/cmes.2023.028612

    Abstract Due to the need for massive device connectivity, low communication latency, and various customizations in 6G architecture, a distributed cloud deployment approach will be more relevant to the space-air-ground-sea integrated network scenario. However, the openness and heterogeneity of the 6G network cause the problems of network security. To improve the trustworthiness of 6G networks, we propose a trusted computing-based approach for establishing trust relationships in multi-cloud scenarios. The proposed method shows the relationship of trust based on dual-level verification. It separates the trustworthy states of multiple complex cloud units in 6G architecture into the state within and between cloud units.… More >

    A Low-Cost and High-Performance Cryptosystem Using Tripling-Oriented Elliptic Curve

    Mohammad Alkhatib*, Wafa S. Aldalbahy

    Intelligent Automation & Soft Computing, Vol.37, No.2, pp. 1807-1831, 2023, DOI:10.32604/iasc.2023.038927

    Abstract Developing a high-performance public key cryptosystem is crucial for numerous modern security applications. The Elliptic Curve Cryptosystem (ECC) has performance and resource-saving advantages compared to other types of asymmetric ciphers. However, the sequential design implementation for ECC does not satisfy the current applications’ performance requirements. Therefore, several factors should be considered to boost the cryptosystem performance, including the coordinate system, the scalar multiplication algorithm, and the elliptic curve form. The tripling-oriented (3DIK) form is implemented in this work due to its minimal computational complexity compared to other elliptic curves forms. This experimental study explores the factors playing an important role… More >
