Abstract

In today’s interconnected world, the increasing connectivity and data exchange in fields such as mobile cyber–physical systems (MCPS) and the internet of things (IoT) create a growing need for secure communication and data protection. Traditional security protocols and blockchain technologies may pose disadvantages in terms of performance and resource usage, especially for resource-constrained devices. This study proposes a comprehensive model that integrates a lightweight and quantum-resistant security protocol with a directed acyclic graph (DAG)-based blockchain structure for resource-constrained MCPS applications. The model is demonstrated using connected vehicles as an example of an MCPS application. The proposed protocol ensures secure communication and data integrity by employing quantum-resistant symmetric and asymmetric encryption. The DAG-based blockchain structure is utilized to reduce computational workload and enhance scalability in these devices. The blockchain is encrypted with AES-256 and hashed with SHA-256. Experimental results demonstrate that the proposed protocol and its integration with a DAG-based blockchain can provide a secure and efficient communication environment for MCPS applications. Security analysis reveals that the protocol is resilient against various attacks, including man-in-the-middle (MITM), denial-of-service (DoS), replay attacks, brute force attacks, and quantum attacks.
一种新的后量子轻量安全模型和基于有向无环图的移动网络物理系统区块链集成
在当今互联互通的世界中,移动网络物理系统(MCPS)和物联网(IoT)等领域的连接性和数据交换日益增加,对安全通信和数据保护的需求日益增长。传统的安全协议和区块链技术在性能和资源使用方面可能存在缺点,特别是对于资源受限的设备。本研究提出了一个综合模型,该模型将轻量级和抗量子安全协议与基于有向无环图(DAG)的区块链结构集成在资源受限的MCPS应用中。该模型以互联汽车为例进行了MCPS应用的演示。该协议通过采用抗量子对称和非对称加密来确保通信的安全性和数据完整性。利用基于dag的区块链结构来减少这些设备中的计算工作负载并增强可伸缩性。区块链采用AES-256加密,SHA-256散列。实验结果表明,该协议及其与基于dag的区块链的集成可以为MCPS应用提供安全高效的通信环境。安全分析表明,该协议能够抵御各种攻击,包括中间人(MITM)、拒绝服务(DoS)、重放攻击、暴力破解攻击和量子攻击。

期刊介绍: The impact of computers has nowhere been more revolutionary than in electrical engineering. The design, analysis, and operation of electrical and electronic systems are now dominated by computers, a transformation that has been motivated by the natural ease of interface between computers and electrical systems, and the promise of spectacular improvements in speed and efficiency. Published since 1973, Computers & Electrical Engineering provides rapid publication of topical research into the integration of computer technology and computational techniques with electrical and electronic systems. The journal publishes papers featuring novel implementations of computers and computational techniques in areas like signal and image processing, high-performance computing, parallel processing, and communications. Special attention will be paid to papers describing innovative architectures, algorithms, and software tools.
