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;
transmitting the generated cloud-based vehicle data security policies to the vehicle along with the pseudonym and the pseudonym certificate,
wherein the program further performs:
before receiving the request to register a cloud-based vehicle data security service from the vehicle,
receiving a message signed with a private key thereof from the vehicle;
verifying the message signed with the private key, which is received from the vehicle, using a public key of the vehicle; and
transmitting a result of authentication of the vehicle to the vehicle,
wherein receiving the request to register a cloud-based vehicle data security service from the vehicle is performed when the vehicle is successfully authenticated.
