摘要：The vehicle to everything (V2X) requires the real-time integration of all kinds of information on roads, pedestrians, the environment, and vehicles themselves. This information also needs to be shared with other vehicles. The effective integration of information and the strong privacy protection are the key restrictions on the development of the V2X. The previous privacy protection model has mainly focused on the centralized network, and there were problems with the centralized gateway and single-point decision, which were not suitable for the decentralized scenario. Therefore, this paper proposes a remote attestation security model based on a privacy-preserving blockchain. The overall model involves two core steps. First, the vehicle provides the network with an evidence of a credible identity and integrity. Secured, the vehicles in the network calculate the nodes to make their respective decisions, and the accounting nodes summarize the sub-conclusions, form the final results, and write them into data blocks. The analysis shows that it possesses the security features of decentralization, traceability, anonymity, irreplaceability, and high efficiency. The model framework, core block chain structure, and protocol process are described in detail. The experimental results based on a realistic infrastructure are presented. These experimental results demonstrate that our scheme can effectively enhance the security of the communications of intelligent vehicles in the V2X.
