Embodiment 1

[0049] figure 1 The present invention shows a schematic diagram of an online certificate status acquisition system for V2X.

[0050] like figure 1 As shown, the first aspect of the present invention proposes an online certificate status acquisition system for V2X, the system includes:

[0051] The requesting terminal is used to generate the certificate status request message body of the digital certificate to be queried, and judge the certificate status of the digital certificate to be queried based on the obtained certificate status response message body;

[0052] The certificate status query mechanism is used to query and obtain the certificate status of the digital certificate to be queried based on the received certificate status request message body, and generate a certificate status response message body; preferably, the certificate status query mechanism can be an OCSP responder;

[0053]The roadside device communicates with the requesting terminal in a short distance...

Embodiment 2

[0071] The difference between this embodiment and embodiment 1 is: as image 3 and Figure 4 As shown, the certificate status inquiry mechanism includes an OCSP responder and an edge network; the OCSP responder performs network communication with the edge network, and is used to synchronize batch certificate status to the edge network in advance;

[0072] The edge network communicates with the drive test device network, receives the certificate status request message body sent by the requesting terminal, and obtains the status of the corresponding digital certificate based on the certificate status request message body, and generates a certificate status response message body , and returned to the drive test device.

[0073] Further, the OCSP responder communicates with the edge network, and the OCSP responder synchronizes the revocation status of the certificate used for V2X to the edge network in real time in advance, and the requester (such as the requesting terminal) can ...

Embodiment 3

[0076] This embodiment provides a communication system for V2X, such as Figure 5 As shown, including the first terminal, the second terminal, the drive test equipment and the certificate status inquiry machine;

[0077] The first terminal is connected to the second terminal for generating a V2X message and sending it to the second terminal;

[0078] The second terminal, the drive test device and the certificate status query unit form the online certificate status acquisition system described in Embodiment 1; wherein, the second terminal serves as a requesting terminal, and through the online certificate status acquisition system acquiring the certificate status of the digital certificate of the first terminal;

[0079] The second terminal verifies the validity of the V2X message based on the certificate status.

[0080] Specifically, when the certificate status of the digital certificate of the sender of the V2X message is valid, the digital certificate of the sender of the...

Abstract

The present invention proposes an online certificate status acquisition method, system and communication method for V2X, including: requesting a terminal, generating a certificate status request message body of a digital certificate to be queried, and judging the status of the certificate to be acquired based on the obtained certificate status response message body. Query the certificate status of the digital certificate; the certificate status query mechanism, based on the received certificate status request message body, query and obtain the certificate status of the digital certificate to be queried, and generate a certificate status response message body; the roadside device sends the request terminal The certificate status request message body is forwarded and routed to the certificate status inquiry institution, and the certificate status response message body responded by the certificate status inquiry institution is forwarded and routed to the requesting terminal. The invention can ensure the safety and reliability of the V2X application environment of the Internet of Vehicles.

Description

technical field [0001] The present invention relates to the field of digital certificates, in particular to a method, system and communication method for obtaining online certificate status for V2X. 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] Digital certificate is the main means to realize security authentication technology. Under normal circumstances, a car may have more types and more digital certificates, such as pseudonym certificates, ...
