- 摘要:
- 在智能交通系统快速发展的背景下，车联网已成为实现智能化交通管理的关键技术。然而，确保车辆间通信的安全性和隐私保护仍是重要挑战。为此，提出了一种基于跨链技术的车联网可信认证系统。系统集成多种密码学和盲签名技术，设计了基于侧链技术的双链车联网架构，优化车辆与路侧单元间的身份认证和数据交换过程。侧链采用拜占庭共识协议，主链存证与哈希锁定，协同保障跨区域数据一致性与安全性。此外，系统利用智能合约模拟双链结构并实现系统参数的自动更新。基于Fabric的仿真实验表明，该系统相比于传统单链的公钥基础设施(public key infrastructure, PKI)方案，将每笔交易计算开销降低了12%～33%，显著提高认证效率，有效解决了传统车联网中心化认证的不足，同时验证了系统的实用性和可扩展性。
- Abstract:
- As intelligent transportation systems rapidly evolve, telematics plays a vital role in enabling efficient traffic management. However, maintaining security and privacy in inter-vehicle communication remains a challenge. To address this issue, we propose a trusted authentication system built on cross-chain technology. The system introduces a dual-chain vehicular networking architecture using side-chain technology, cryptographic methods, and blind signature schemes to enhance authentication and facilitate secure data exchange between vehicles and roadside units. The side chain adopts a Byzantine consensus protocol, while the main chain employs deposit-based validation and hash locks to maintain data consistency and ensure cross-regional security. Smart contracts are used to emulate the dual-chain structure and support the dynamic updating of system parameters. Fabric-based simulation experiments demonstrate a 12%–33% reduction in computational overhead per transaction compared with traditional single-chain PKI-based schemes. The results confirm significant improvements in authentication efficiency, address the limitations of centralized authentication in vehicular networks, and validate the system’s scalability and practical applicability.
