Embodiment Construction

[0048]In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following detailed description will be given in conjunction with the accompanying drawings and specific embodiments.

[0049] like figure 1 As shown, the technical solution of this embodiment involves the following devices:

[0050] On-board terminal (On Board Unit, OBU), that is, the OBU installed on the vehicle (such as smart rearview mirror, smart car machine, etc.), supports Uu communication and PC5 communication, on the one hand, through Uu communication, obtain certificates from edge computing nodes, On the other hand, by monitoring the PC5 broadcast, it can obtain early warning information such as traffic light information and road events, and verify the signature of the data through the obtained certificate.

[0051] Edge computing nodes, namely V2X edge computing nodes, with the popularization of Internet of Things ap...

Abstract

The invention provides a direct communication authentication method and device, and belongs to the technical field of communication. The direct connection communication authentication method is applied to an edge computing node and comprises the steps that an authentication application sent by a vehicle-mounted unit is received, and the authentication application requests to verify the identity of a vehicle carrying the vehicle-mounted unit; and after the identity verification of the vehicle is passed, issuing M-ID identifiers and a key Kd list of the vehicle-mounted unit and other edge computing nodes having a topological relation with the vehicle-mounted unit to the vehicle-mounted unit. According to the technical scheme, the service continuity can be guaranteed, frequent authentication in the vehicle driving process is reduced, and direct connection communication between the vehicles can be achieved without multiple times of authentication on the vehicles within the coverage range of the adjacent heterogeneous edge computing nodes.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a method and device for authentication of direct connection communication. Background technique [0002] At present, there are mainly two types of authentication mechanisms for the direct connection of the Internet of Vehicles: [0003] 1. Use the PKI (Public Key Infrastructure) mechanism based on public key certificates to achieve secure authentication and secure communication. In the process of direct connection communication, the IoV terminal uses the CA (Certification Authority, certificate authority) public key to digitally sign the transmitted message, so as to realize the security authentication of the legal identity of the terminal and the security authentication of the message content. [0004] The above technologies are independent of the cellular network, but their implementation relies on the PKI public key infrastructure, which is limited by the solutio...
