1. A cloud center device, comprising:
memory in which at least one program is recorded; and
a processor for executing the program,
wherein the program performs:
generating cloud-based vehicle data security policies, which are formats of data to be stored in a cloud, and a pseudonym for a vehicle in response to a request to register a cloud-based vehicle data security service from the vehicle;
requesting an authentication center to generate a pseudonym certificate for the generated pseudonym and receiving the pseudonym certificate generated by the authentication center;
