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.

First claim

What is claimed is:

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.
