Misbehaviour warnings in intelligent transportation systems

1. A method, comprising:

determining, by a network server, that an intelligent transportation system (ITS) station is misbehaving;

in response to the network server determining that the ITS station is misbehaving, transmitting, by the network server, a misbehaviour warning message to the ITS station indicating that the ITS station is misbehaving;

after transmitting the misbehaviour warning message, determining, by the network server, whether the ITS station continues to misbehave after the network server transmitting the misbehaviour warning message; and

in response to determining that the ITS station continues to misbehave after the misbehaviour warning message:

including, by the network server, information of the ITS station in a certificate revocation list (CRL), wherein the information of the ITS station comprises at least a linkage seed associated with an elliptic-curve Qu-Vanstone (ECQV) implicit certificate issued to the ITS station by a certificate authority; and

broadcasting, by the network server, the CRL that includes the information of the ITS station.

2. The method of claim 1 , further comprising:

in response to determining that the ITS station is misbehaving, including the information of the ITS station in a misbehaviour warning list (MWL), wherein the MWL is different than the CRL; and

in response to determining that the ITS station is continuing to misbehave, removing the information of the ITS station from the MWL.

3. The method of claim 2 , further comprising:

determining, at the network server, that a second ITS station is misbehaving;

in response to determining that the second ITS station is misbehaving, including information of the second ITS station in the MWL;

transmitting a second misbehaviour warning message to the second ITS station indicating that the second ITS station is misbehaving; and

in response to transmitting the second misbehaviour warning message and determining that the second ITS station is no longer misbehaving, removing the information of the second ITS station from the MWL.

4. The method of claim 3 , further comprising:

in response to transmitting the second misbehaviour warning message, receiving, from the second ITS station, a query message requesting information of misbehaviour.

5. The method of claim 3 , wherein determining that the second ITS station is no longer misbehaving comprises receiving, from the second ITS station, an indication indicating that the second ITS station is no longer misbehaving.

6. The method of claim 1 , wherein the misbehaviour warning message includes information of misbehaviour.

7. The method of claim 1 , wherein the ITS station is deployed on a vehicle.

8. A network server, comprising:

a memory; and

at least one hardware processor communicatively coupled with the memory and configured to:

determine that an intelligent transportation system (ITS) station is misbehaving;

in response to the network server determining that the ITS station is misbehaving, transmit a misbehaviour warning message to the ITS station indicating that the ITS station is misbehaving;

after transmitting the misbehaviour warning message, determine whether the ITS station continues to misbehave after the network server transmitting the misbehaviour warning message; and

in response to determining that the ITS station continues to misbehave after the misbehaviour warning message:

include information of the ITS station in a certificate revocation list (CRL), wherein the information of the ITS station comprises at least a linkage seed associated with an elliptic-curve Qu-Vanstone (ECQV) implicit certificate issued to the ITS station by a certificate authority; and

broadcast the CRL including the information of the ITS station.

9. The network server of claim 8 , wherein the at least one hardware processor is further configured to:

in response to determining that the ITS station is misbehaving, include the information of the ITS station in a misbehaviour warning list (MWL), wherein the MWL is different than the CRL; and

in response to determining that the ITS station is continuing to misbehave, remove the information of the ITS station from the MWL.

10. The network server of claim 9 , wherein the at least one hardware processor is further configured to:

determine that a second ITS station is misbehaving;

in response to determining that the second ITS station is misbehaving, include information of the second ITS station in the MWL;

transmit a second misbehaviour warning message to the second ITS station indicating that the second ITS station is misbehaving; and

in response to transmitting the second misbehaviour warning message and determining that the second ITS station is no longer misbehaving, remove the information of the second ITS station from the MWL.

11. The network server of claim 10 , wherein the at least one hardware processor is further configured to:

in response to transmitting the second misbehaviour warning message, receive, from the second ITS station, a query message requesting information of misbehaviour.

12. The network server of claim 10 , wherein determining that the second ITS station is no longer misbehaving comprises receiving, from the second ITS station, an indication indicating that the second ITS station is no longer misbehaving.

13. A non-transitory computer-readable medium containing instructions which, when executed, cause a network server to perform operations comprising:

determining that an intelligent transportation system (ITS) station is misbehaving;

in response to the network server determining that the ITS station is misbehaving, transmitting a misbehaviour warning message to the ITS station indicating that the ITS station is misbehaving;

after transmitting the misbehaviour warning message, determining whether the ITS station continues to misbehave after the network server transmitting the misbehaviour warning message; and

in response to determining that the ITS station continues to misbehave after the misbehaviour warning message:

including information of the ITS station in a certificate revocation list (CRL), wherein the information of the ITS station comprises at least a linkage seed associated with an elliptic-curve Qu-Vanstone (ECQV) implicit certificate issued to the ITS station by a certificate authority; and

transmitting the CRL including the information of the ITS station.

14. The non-transitory computer-readable medium of claim 13 , wherein the operations further comprise:

in response to determining that the ITS station is misbehaving, including the information of the ITS station in a misbehaviour warning list (MWL), wherein the MWL is different than the CRL; and

in response to determining that the ITS station is continuing to misbehave, removing the information of the ITS station from the MWL.

15. The non-transitory computer-readable medium of claim 14 , wherein the operations further comprise:

determining that a second ITS station is misbehaving;

in response to determining that the second ITS station is misbehaving, including information of the second ITS station in the MWL;

transmitting a second misbehaviour warning message to the second ITS station indicating that the second ITS station is misbehaving; and

in response to transmitting the second misbehaviour warning message and determining that the second ITS station is no longer misbehaving, removing the information of the second ITS station from the MWL.

16. The non-transitory computer-readable medium of claim 15 , wherein the operations further comprise:

in response to transmitting the second misbehaviour warning message, receiving, from the second ITS station, a query message requesting information of misbehaviour.

17. The non-transitory computer-readable medium of claim 15 , wherein determining that the second ITS station is no longer misbehaving comprises receiving, from the second ITS station, an indication indicating that the second ITS station is no longer misbehaving.
