Internet of Vehicles cross-domain authentication method based on side chain technology trust model

Abstract

The invention provides an Internet of Vehicles cross-domain authentication method based on a side chain technology trust model. The Internet of Vehicles cross-domain authentication method comprises the following steps: S10, an initialization and registration stage; S20, a cross-domain vehicle identity verification stage; S30, repeating a cross-domain authentication stage; and S40, in an identity logout stage, if the RSU receives a plurality of logout applications for the same vehicle ID, informing a CA center of the logout applications, the CA center binding the identity ID of the vehicle to be logged out with a logout identifier 'REVOKE' and signing and disclosing the logout identifier 'REVOKE' in a main chain layer, and if the intelligent contract retrieves that the vehicle identity ID is marked with 'REVOKE', indicating that the vehicle identity is logout and cannot access a network. According to the Internet of Vehicles cross-domain authentication method based on the side chain technology trust model, the block chain side chain technology is innovatively applied to cross-domain identity authentication research of the Internet of Vehicles, and unforgeability, tamper resistance and traceability of vehicle identities are guaranteed through the characteristics of block chain distributed data storage and the like; the problem of centralized single-point failure of a cross-domainauthentication mechanism of the traditional Internet of Vehicles is solved.

Description

technical field

[0001] The invention relates to the technical field of security application of the Internet of Vehicles, in particular to a cross-domain authentication method for the Internet of Vehicles based on a side chain technology trust model. Background technique

[0002] The Internet of Vehicles is a system that uses vehicles as mobile sensing objects to perform wireless communication and interconnection perception between vehicles and X (vehicles, roads, Internet, etc.), and realize the integration of traffic intelligent management, service intelligent decision-making and vehicle intelligent control. Identity authentication is an important security mechanism to ensure the security of Internet of Vehicles information, and identity authentication based on Public Key Infrastructure (PKI) is currently a relatively mature and widely used authentication technology. In the Internet of Vehicles environment, the trusted authority (certification center, or CA) of the public k...
