Secure Inter-Vehicle Communication Using Blockchain-Based Distributed Security Frameworks
Year: 2026
Type: conference-paper
Abstract: Although secure and reliable communication among vehicles is essential for intelligent transport systems (ITS) and full automation of driving, traditional frameworks for vehicular communication have weaknesses concerning data loss and vandalism, node impersonation, and denial of service (DoS). This paper presents an innovative security framework based on blockchain technology for wireless vehicular communication systems, where vehicles exchange messages using cryptographic techniques (hashing algorithms and digital signatures), with decentralized validation and a blockchain-based reputationvoting consensus (RVPC) system. The proposed architecture allows vehicles to authentically and securely exchange messages, maintaining the integrity of the data through blockchain. Each vehicle creates a replica of the vehicle and the vehicle becomes an owner of the vehicle, having the ability to transmit messages and create signed messages. Thus, received messages can be validated by the neighboring vehicles. A decentralized consensus mechanism, based on vehicle reputation and voting thresholds, is used to improve trust and fault tolerance in the communication network. Test results confirm that the proposed system demonstrates a remarkable improvement in communication, compared to existing vehicular blockchain approaches. With a latency of 50 ms, a throughput of 1.20 Tx/sec, a scalability of 95%, and a security level of 98%, the system outperforms all existing Proof of Work vehicular blockchain systems with 150 ms latency and a throughput of 0.6 Tx/sec. Additionally, the proposed system demonstrates maximum performance with an average of 3.8 J energy consumption, compared to 9.5 J in Proof of Work systems. Additionally, the proposed system attains 1400 TPS transaction speed, 2 seconds block time, and 15% network overhead, facilitating effective real-time communication between vehicles. These metrics prove that the proposed blockchain technology based system offers next-generation intelligent transport systems a communication infrastructure that prioritizes scalability, energy efficiency, and security.
