摘要:

随着汽车工业和物联网技术的快速发展，车联网(IoV)技术受到了越来越多的关注。车联网能够提高运输效率，促进车辆间的信息共享和合作。然而，由于该网络的高机动性和波动性等特质，车辆间的信任和隐私仍然是一个亟待解决的问题。对于车联网来说，防止内部车辆接收伪造信息的同时保护车辆隐私免受跟踪攻击是至关重要的。为解决上述问题，本文提出了一种基于区块链的安全数据共享机制。在该机制中，共享信息和车辆的信誉值是通过区块链进行存储的，为了激励更多车辆参与道路信息共享，车辆发布真实的交通信息可以获得数字货币奖励。该机制不仅通过多重签名技术和信誉机制验证共享信息的可信性，而且还使用基于用户隐私需求的假名替换技术确保用户信息的隐私性。最后，理论分析和仿真实验表明该机制可以有效地提升车联网中信息共享的安全性和可靠性。

Abstract:

A secure data sharing mechanism based on blockchain was proposed aiming at the security and privacy issues of vehicle sharing information in the Internet of Vehicles. In this mechanism, the shared message and reputation value were stored through the blockchain based on the DAG structure, and the storage burden of the vehicle would be reduced. The malicious information in the network was excluded through the reputation mechanism. In addition, a pseudonym substitution strategy based on user privacy needs was introduced, which parameterize vehicle driving goals and driver privacy protection needed. A calculation method for the replacement interval of pseudonyms was proposed, which redefined the frequency of pseudonym replacement. Experiments showed that when the malicious nodes in the network reached 30%, the accuracy of the vehicle recei-ving information was higher than 91%, the mechanism could effectively improve the safety and reliability of information sharing in the Internet of Vehicles.
