Abstract: An apparatus for a vehicle-to-everything (V2X) service establishes a secure session with a V2X server by using a transport layer security (TLS) handshake on the basis of an X.509 certificate of the V2X server. The apparatus generates a signed V2X message having a digital signature generated on the basis of a pseudonym certificate. The apparatus encodes the signed V2X message on the basis of the X.509 certificate.

Abstract: A method of operating a message exchange server related to vehicle-to-everything (V2X) message transmission and reception in a wireless communication system can include obtaining, by the message exchange server, information of an adjacent message exchange server from a lookup server; and receiving, by the message exchange server, a message published by a User Equipment (UE). Also, in response to determining, by the message exchange server, that a topic included in the message published by the UE is not included in a topic list of the message exchange server, the method can further include transmitting, by the message exchange server, a handover message to the UE.

Abstract: A server for a vehicle-to-everything (V2X) service receives, from a first V2X device, a subscription request for requesting subscription of the V2X service, and sets a subscription area for the first V2X device. The server publishes, to the first V2X device, at least one V2X message published by at least one second V2X device associated with the subscription area.
