Abstract

The invention relates to an Internet-of-Vehicles hierarchical authentication method based on a blockchain technology, and belongs to the technical field of Internet of Vehicles. The method comprises the following steps: S1, based on a hierarchical certificate service model of a block chain, constructing a hierarchical authentication network composed of three levels of authentication mechanisms ona mainstream block chain platform; S2, performing a hierarchical reputation consensus mechanism; S3, dynamically managing the entities on the chain based on the reputation points and the authentication behaviors in the two consensus intervals, namely rejecting unreliable authentication entities and adding new authentication entities; and S4, performing rapid or security verification, wherein the rapid verification time efficiency is high, and the security verification can improve the reliability of the entity in a long-distance complex communication scene. Reliability and safety of the distributed authentication entity can be effectively guaranteed, expandability and efficiency of consensus are improved through a consensus mechanism based on reputation points, and certificate verificationis more flexible in safety and time efficiency selection through a new verification mode.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, and relates to a layered authentication method for the Internet of Vehicles based on block chain technology. Background technique [0002] Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing paradigm for programming and manipulating data through smart contracts composed of code. Blockchain technology has the characteristics of decentralization, tamper-proof, public audit, transparency, distributed trust consensus, and autonomous programming. Generally speaking, blockchain is divided into data layer, network layer, consensus layer, contract layer and application layer from bottom to top. Nowadays, blockchain techn...
