METHOD AND SYSTEM FOR DISTRIBUTING CERTIFICATE REVOCATION LIST FOR VEHICLE COMMUNICATION, APPARATUS FOR ACQUIRING CERTIFICATE REVOCATION LIST THEREOF

摘要

invention, terrestrial multimedia broadcasting (DMB) channels used to communicate on the vehicle used for certificate revocation lists the distribution and proper vehicle relates to communication certificate revocation list distribution techniques to acquire, for this purpose, unlike the aforementioned conventional method for distributing the certificate revocation list of vehicles using the road or around the vehicle peripherals, delivered from the distribution unit conversion certificate revocation lists in the vehicle communication (CRL) of the CRL of data available for transmission vehicle terminals via a broadcast channel, and insert the converted CRL data for data broadcast channel of a terrestrial multimedia broadcasting (DMB) and distributed via the broadcast repeater by the broadcast terminal is mounted on the vehicle can acquire the CRL of the vehicle in real-time communication. Accordingly, the present invention can be distributed in real-time distribution of a sufficient interval (period) CRL, regardless of the size and because of the use of the DMB data services having sufficient bandwidth, CRL is stored in the vehicle data of the vehicle for communication via this communication device can be secured, because the most recent data always be maintained in a malicious attack vehicle or vehicles can block the communication failure to use the revoked certificates effectively secure the safety of the vehicle communication securely, also the size of the CRL (volume) and the CRL data communication, regardless of the vehicle can be deployed very short period to ensure the reliability is on the CRL is stored in the vehicle data communication apparatus. ;
