Method and system for intelligent transportation system certificate revocation list reduction

A computing device within a vehicle Intelligent Transportation System (ITS) endpoint, the computing device comprising:

• a processor;
• and
• a communications subsystem,
• wherein the computing device is configured to:
• receive a trigger event;
• based on the trigger event, compose a first message, the first message including at least tailoring information for the endpoint and intended journey details for the endpoint, the intended journey details comprising at least one time stamp, each time stamp of the at least one time stamp being associated with a geographic location, where the tailoring information comprises one or more of:
• location information for the endpoint;
• one or more endpoint identifiers belonging to the endpoint;
• or one or more certificates or identities of ITS endpoints that have communicated with the endpoint within a threshold time period;
• send the first message to a certificate revocation list (CRL) provisioning server;
• and
• receive, from the CRL provisioning server, a tailored certificate revocation list.

A non-transitory computer readable medium for storing instruction code, which, when executed by a processor of a computing device within a vehicle Intelligent Transportation System (ITS) endpoint cause the computing device to:

• receive a trigger event;
• based on the trigger event, compose a first message, the first message including at least tailoring information for the endpoint and intended journey details for the endpoint, the intended journey details comprising at least one time stamp, each time stamp of the at least one time stamp being associated with a geographic location, where the tailoring information comprises one or more of:
• location information for the endpoint;
• one or more endpoint identifiers belonging to the endpoint;
• or one or more certificates or identities of ITS endpoints that have communicated with the endpoint within a threshold time period;
• send the first message to a certificate revocation list (CRL) provisioning server;
• and
• receive, from the CRL provisioning server, a tailored certificate revocation list.
