IOV Privacy Protection System Based on Double-Layered Chains

الملخص EN

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.
