9. The V2X platform according to claim 7, wherein the vehicle information comprises at least: position information of the vehicle;

the first processor is specifically configured to determine, from the RSU topology, at least two RSU units that match the vehicle based on matching the position information of the vehicle with the position information of RSU units.

10. The V2X platform according to claim 7, wherein said first processor is specifically configured to determine from said RSU topology at least one RSU unit having an N-level topological relationship with said first RSU unit, N being a positive integer.

11. The V2X platform of claim 7, further comprising in the vehicle information: movement information of the vehicle;

the first processor is specifically configured to determine, from the RSU topology structure, at least one RSU unit that has an M-layer topological relationship with the first RSU unit and matches with the movement information of the vehicle, where M is a positive integer.

12. The V2X platform of claim 7, wherein the vehicle information includes at least: path information of the vehicle;

the first processor is specifically configured to determine, from the RSU topology, at least two RSU units whose positions have an overlapping region with the path of the vehicle based on matching the path information of the vehicle with the position information of the RSU units.

13. A V2X platform, the V2X platform comprising: a second processor and a memory; wherein, the first and the second end of the pipe are connected with each other,

the second processor is configured to execute a program stored in the memory to implement the steps of:

receiving an authentication application from a vehicle; the authentication application at least comprises vehicle information;

determining at least two RSU units matched with the vehicle from the RSU topological structure based on the matching of the vehicle information and the RSU units in the RSU topological structure; wherein the determining at least two RSU units matching the vehicle from the RSU topology comprises: determining the RSU unit closest to the vehicle as a first RSU unit; determining, based on the first RSU unit, at least one second RSU unit associated with the first RSU unit;

and sending the key information of the at least two RSU units to the vehicle, wherein the key information is used for analyzing the broadcast message of the corresponding RSU unit.

14. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the method according to any one of claims 1 to 6.
