Abstract

A method for issuing a reliable certificate to a vehicle for a vehicle-to-anything (V2X) communication in a server on a network comprises receiving a certificate issue request including vehicle identification information and road-side unit (RSU) identification information from an RSU. Log information for the certificate issue request is extracted from a database. Normality or abnormality is determined according to whether a predetermined certificate issue criteria is satisfied by analyzing the certificate issue request and the log information. The certificate is issued and the certificate is transmitted to a vehicle communication module according to determination of normality, or certificate revocation information is registered according to determination of abnormality.

Claims

1. A method for issuing a reliable certificate to a vehicle for a vehicle-to-anything (V2X) communication in a server on a network, the method comprising steps of:

(a) receiving a certificate issue request including vehicle identification information and road-side unit (RSU) identification information from an RSU;

(b) extracting log information for the certificate issue request from a database;

(c) determining normality or abnormality according to whether a predetermined certificate issue criteria is satisfied by analyzing the certificate issue request and the log information; and

(d) issuing the certificate and transmitting the certificate to a vehicle communication module according to determination of normality, or registering certificate revocation information according to determination of abnormality.

2. The method according to claim 1, wherein the RSU receives the vehicle identification information for requesting the certificate issue request from the vehicle communication module supporting a wireless access in vehicular environment (WAVE) communication.

3. The method according to claim 1, wherein the log information includes whether a certificate signing request (CSR) certificate corresponding to the vehicle identification information is issued or a certificate of the log information, an RSU position for the certificate issue request, or a certificate issue request time.

4. The method according to claim 1, wherein the certificate issue criteria includes whether the corresponding issue request is correct, whether an RSU position is suitable, or whether a certificate issue request time in a corresponding RSU position is adequate.

5. The method according to claim 1, wherein the step (c) includes a step of determining whether the RSU identification information is registered in the database.

6. The method according to claim 1, wherein the step (c) includes a step of determining whether a previously issued CSR certificate corresponding to the vehicle identification information exists or is issued in the log information and verifying whether it is valid.

7. The method according to claim 1, wherein the step (c) includes a step of determining whether the certificate issue request is an issue request after a predetermined time or more is elapsed since a previous issue request time by referring to the log information.

8. The method according to claim 1, wherein the step (c) includes a step of determining whether a corresponding RSU position for the certificate issue request is suitable by referring to the log information.

9. The method according to claim 1, wherein the step (c) includes a step of determining whether a certificate issue request time in a corresponding RSU position for the certificate issue request is adequate.

10. A system for issuing a reliable certificate to a vehicle for a V2X communication, the system comprising:

a misbehavior processor configured to receive a certificate issue request including vehicle identification information and RSU identification information from an RSU and extract log information for the certificate issue request from a database; and

a misbehavior detection engine configured to determine normality or abnormality according to whether a predetermined certificate issue criteria is satisfied by analyzing the certificate issue request and the log information,

wherein the system issues the certificate and transmits the certificate to a vehicle communication module according to determination of normality, or registers certificate revocation information according to determination of abnormality.

11. The system according to claim 10, wherein the RSU receives the vehicle identification information for requesting the certificate issue request from the vehicle communication module supporting a WAVE communication.

12. The system according to claim 10, wherein the log information includes whether a CSR certificate corresponding to the vehicle identification information is issued or a certificate of the log information, an RSU position requesting the certificate issue, or a certificate issue request time.

13. The system according to claim 10, wherein the certificate issue criteria includes whether the corresponding issue request is correct, whether an RSU position is suitable, or whether a certificate issue request time in a corresponding RSU position is adequate.

14. The system according to claim 10, wherein the misbehavior detection engine determines whether the RSU identification information is registered in the database.

15. The system according to claim 10, wherein the misbehavior detection engine determines whether a previously issued CSR certificate corresponding to the vehicle identification information exists or is issued in the log information and verifies whether the previously issued CSR certificate is valid.

16. The system according to claim 10, wherein the misbehavior detection engine determines whether the certificate issue request is an issue request after a predetermined time or more is elapsed since a previous issue request time by referring to the log information.

17. The system according to claim 10, wherein the misbehavior detection engine determines whether a corresponding RSU position for the certificate issue request is suitable by referring to the log information.

18. The system according to claim 10, wherein the misbehavior detection engine determines whether a certificate issue request time in a corresponding RSU position for the certificate issue request is adequate.

19. The system according to claim 10, wherein the system issues the certificate or registers the certificate revocation information in a certificate authority (CA) server of a certificate authority for generating, issuing, and managing the certificate, and transmits the certificate issued from a registration authority (RA) server operated by a registration authority for relaying a certification registration to the vehicle communication module through the RSU.
