The blockchain-based management system has been regarded as a novel way to improve the efficiency and safety of Vehicular Ad Hoc Networks (VANETs). A blockchain-based scheme’s performance depends on blockchain nodes’ computing power composed from the road-side unit (RSU). However, the throughput of blockchain-based application in VANETs is limited by the network bandwidth. A single blockchain cannot record large-scale VANETs’ data. In this paper, we design an atomic cross-chain swap-based management system (ACSMS) to boost the scalability of blockchain-based application in VANETs. The blockchain-based public-key encryption with keyword search is further introduced to protect user privacy. The analysis shows that ACSMS achieves cross-chain swap without loss of CAV security privacy. The simulation results show that our method can realize multiple blockchain-based applications in VANETs.

车载Ad Hoc网络中基于原子跨链交换的管理系统

基于区块链的管理系统已被视为提高车辆自组织网络（VANET）的效率和安全性的一种新颖方法。基于区块链的方案的性能取决于路边单元（RSU）构成的区块链节点的计算能力。但是，VANET中基于区块链的应用程序的吞吐量受到网络带宽的限制。单个区块链无法记录大规模VANET的数据。在本文中，我们设计了一个基于原子跨链交换的管理系统（ACSMS），以提高VANET中基于区块链的应用程序的可伸缩性。进一步引入了带有关键字搜索的基于区块链的公钥加密，以保护用户隐私。分析表明，ACSMS可以在不损失CAV安全隐私的情况下实现跨链交换。
