A hierarchical authentication method for Internet of Vehicles based on blockchain technology

Abstract

The invention relates to a layered authentication method for the Internet of Vehicles based on block chain technology, which belongs to the technical field of the Internet of Vehicles. The method includes: S1: a layered certificate service model based on blockchain, constructing a layered authentication network composed of three-level authentication agencies on the mainstream blockchain platform; S2: layered reputation consensus mechanism; S3: reputation-based Points and authentication behaviors within two consensus intervals dynamically manage entities on the chain, that is, eliminate unreliable authentication entities and the addition of new authentication entities; S4: fast or security verification, fast verification time efficiency is high, and security verification can be improved Reliability of entities in complex communication scenarios over long distances. The present invention can effectively guarantee the reliability and security of distributed authentication entities, and at the same time, the consensus mechanism based on reputation points improves the scalability and efficiency of the consensus, and the new verification method makes certificate verification more efficient in terms of security and time efficiency. Choices are more flexible.

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...

Problems solved by technology

However, in the decentralized verification system, there are problems that the credibility of distributed verification nodes is difficult to measure and the dynamic reward and punishment management mechanism is not perfect.

Although the authentication mechanism for the blockchain utilizes the security features of the blockchain, most of them are based on the traditional consensus mechanism or simply use the blockchain to store important information. There is no authentication structure and consensus mechanism that is truly suitable for the Internet of Vehicles. Proposed
