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.
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.
