Embodiment 1

[0046] Such as figure 1 with figure 2 As shown, a V2X-based digital certificate application method includes:

[0047] Step S101, the vehicle-mounted terminal generates a digital certificate application request, and sends the digital certificate application request to the certificate access server;

[0048]Step S102, the certificate access server forwards the digital certificate application request to the certificate registration server;

[0049] Step S103, the certificate registration server verifies the digital certificate application request, and after the verification is passed, sends the digital certificate issuance request to the certificate issuance server, and returns a digital certificate application response to the certificate access server at the same time;

[0050] Step S104, the certificate issuing server issues the digital certificate and returns it to the certificate registration server;

[0051] Step S105, the certificate registration server receives the dig...

Embodiment 2

[0074] The difference between this embodiment and Embodiment 1 is that roadside equipment is added on the basis of Embodiment 1, because in specific application scenarios, vehicle-mounted terminals (such as vehicles) may not have an available Uu network interface, that is, they cannot communicate with The certificate access server is directly connected to the network. At this time, the roadside equipment can be used to transfer information, that is, the vehicle-mounted terminal and the roadside equipment can conduct short-distance communication through PC5 point-to-point.

[0075] The specific process is:

[0076] In step S101, the vehicle-mounted terminal performs short-distance communication with the roadside device, and after the vehicle-mounted terminal generates a digital certificate application request, it sends the digital certificate application request to the certificate access server through the roadside device;

[0077] In step S103, the certificate access server re...

Embodiment 3

[0083] Such as figure 2 As shown, this embodiment provides a V2X-based digital certificate application system, including a certificate access server, a certificate registration server, and a certificate issuance server; the certificate registration server is respectively connected to the certificate access server and the certificate issuance server. The server; when the vehicle-mounted terminal applies for a digital certificate, execute the steps of the V2X-based digital certificate application method described in Embodiment 1.

Abstract

The invention provides a V2X-based digital certificate application method and system, and the method comprises the steps that a vehicle-mounted terminal generates a digital certificate application request, and transmits the digital certificate application request to a certificate access server; the certificate access server forwards the digital certificate application request to a certificate registration server; the certificate registration server verifies the digital certificate application request, sends the digital certificate issuing request to the certificate issuing server after the digital certificate application request passes the verification, and returns a digital certificate application response to the certificate access server; the certificate issuing server issues a digital certificate and returns the digital certificate to the certificate registration server; the certificate registration server receives the digital certificate, compresses the digital certificate to forma download packet, and synchronizes the download packet to the certificate access server; and the vehicle-mounted terminal requests the certificate access server to download the compressed packet of the digital certificate according to the received digital certificate application response forwarded by the certificate access server.

Description

technical field [0001] The present invention relates to the field of digital certificates, in particular to a V2X-based digital certificate application method and system. Background technique [0002] V2X applications of the Internet of Vehicles, the Internet, and the mobile Internet will also face a variety of network security attacks. Attacks on Internet of Vehicles applications will bring greater harm to individuals and society. Security authentication technology is very important. It fundamentally establishes a trust system for vehicles, facilities, networks, and users, and realizes identity verification and message integrity verification. It is the first line of security defense for V2X applications in intelligent connected vehicles. [0003] Registration certificate agency: used to be responsible for the issuance of registration certificates (EC), and registration certificate agencies are generally operated by car companies. [0004] Certificate registration authority...
