1. A device for vehicle-to-everything (V2X) service, the device comprising:
a processor; and
a memory operatively coupled with the processor and configured to store instructions that, when executed by the processor, cause the device to perform functions comprising:
acquiring a pseudonym certificate from a certification authority;
establishing a secure session with a V2X server using a Transport Layer Security (TLS) handshake based on X.509 certificate of the V2X server;
generating an encrypted signed V2X message by encrypting a signed V2X message with a digital signature generated based on the pseudonym certificate based on the X.509 certificate, the signed V2X message including a V2X ID randomly generated by the device and location information of the device; and
transmitting the encrypted signed V2X message to the V2X server.
