Abstract
As the Internet of Vehicle (IOV) being widely applied throughout our daily life, how to secure data privacy of each vehicle is nowadays a hot topic. Taking an aim of solving this problem, a privacy protection system on double-layered chain basis is designed to eliminate the said security risk during vehicle data communication. At the same time, the nontampering nature of the block chain is used to realize reasonable arbitration in traffic accident disputes, vehicle insurance claims, and other states of affairs. Specifically, an IOV double-layered chain model is constructed to simulate a semicentralized system that is convenient for government to supervise; also, a RSA protocol based on zero-knowledge proof (ZKP) is designed to bring safety and zero-knowledge property to the system; finally, we give the application scenario of this IOV privacy protection system based on double-layered chain that it can be widely used in vehicle-sharing industry. The communication costs, respectively, under double-layered chain and single-layered chain frameworks, are compared to prove that the double-layered structure does save cost. Thus an IOV privacy scheme that is safer and more cost-efficient is given.

With the rapid development of science and technology, vehicles have been used at a large scale in the modern society
Chen et al introduce a light-weight and anonymous aggregation protocol based on fog computing-based V2I communication scenario [19]; this paper proposes the Internet of Vehicles (IOV) privacy protection system based on blockchain design and solves the problem with its ability of anticollusion
We have designed a double-layered chain IOV model by investigating the current privacy protection model of vehicle network, which aimed at the assumption that the cloud is not necessarily credible in real life
Summary
With the rapid development of science and technology, vehicles have been used at a large scale in the modern society. In order to solve this problem, we consider making use of the nontampering nature of the block chain to ensure the authenticity of the data in traffic accident disputes, vehicle insurance claims, and other situations requiring arbitration. We formulate the RSA digital signature agreement based on zero-knowledge proof It prevents roadside unit from obtaining any information from signature and establishes the private data protection system for the automatic double-layered chain vehicle network. It increases the data credibility in traditional models, reduces the excessively channel resource consumption in vehicle network, and prohibits opponents from forging RSU to obtain information
