Abstract

The invention provides a blockchain-based vehicle trusted authentication and caching method, including establishing a vehicle trusted authentication architecture; establishing a system transmission model based on the vehicle trusted authentication architecture; establishing a vehicle on the blockchain based on the system transmission model Trusted authentication mechanism; when the edge node detects that a new vehicle enters its coverage area, it authenticates and authorizes the new vehicle; after the new vehicle is authenticated and authorized, it finds the corresponding location matrix and cache matrix in the blockchain network layer, And obtain the delay relationship between the new vehicle and the edge node to construct the objective function: transform the objective function into an optimal matching problem based on the edge node and the new vehicle, and use the many-to-many matching algorithm to find the optimal solution of the objective function, and obtain The minimum average latency for a new vehicle to obtain the required data from the blockchain network layer. The implementation of the invention can solve the vehicle's requirements for credible authentication and low delay.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a blockchain-based method for vehicle trusted authentication and caching. Background technique [0002] With the development of industrial Internet of Things technology in the Internet of Vehicles, data sharing between vehicles is becoming more and more frequent, which also poses a serious threat to data security and privacy security. In order to realize real-time monitoring of vehicles and promote data sharing between devices, an authentication system that can realize trusted access is extremely needed. The blockchain that provides credible authentication and privacy security is also regarded as a key technology to solve the credible authentication problem. Due to the mobility of vehicles and their widespread distribution, the Internet of Vehicles model built solely on the blockchain network cannot cover all smart vehicles. At the same time, the data flood generat...
