when the received random data and the generated random data match each other, register the user device as the general device or the temporary device, and store at least a portion of the user information and the device information included in the authentication request in a memory.

7. The device registration and authentication apparatus of claim 6 , wherein the generated random data comprises first random data corresponding to registration as a general device and second random data corresponding to registration as a temporary device, and

the processor is configured to:

register the user device as a general device when the received random data matches the first random data; and

register the user device as a temporary device when the received random data matches the second random data.

8. The device registration and authentication apparatus of claim 2 , wherein the processor controls a registration process for registering the user device as a master device, a general device, or a temporary device when it is detected that the user has the FOB and there is another device registered as a master device.

9. The device registration and authentication apparatus of claim 8 , wherein the processor is configured to:

generate random data for authentication of the user device;

transmit the generated random data according to random data destination information of another device registered as the master device;

when random data is input through the user device in response to the transmission of the random data, receive the input random data from the user device; and

register the user device as a master device, a general device, or a temporary device based on the received random data, and store at least a portion of the user information and the device information included in the authentication request in a memory.

10. The device registration and authentication apparatus of claim 9 , wherein the generated random data comprises first random data corresponding to registration as a general device, second random data corresponding to registration as a temporary device, and third random data corresponding to registration as a master device, and

the processor is configured to:

register the user device as a general device when the received random data matches the first random data;

register the user device as a temporary device when the received random data matches the second random data; and

register the user device as a master device when the received random data matches the third random data, and cancel registration of another device previously registered as a master device.

11. The device registration and authentication apparatus of claim 1 , wherein the processor is configured to:

estimate a distance between the vehicle and the user device using the communication unit or a relative location of the user device with respect to the vehicle;

estimate, by using the at least one antenna, a distance between the vehicle and the FOB or a relative location of the FOB with respect to the vehicle; and

check that the user has the FOB when a difference between the estimated distances or the relative locations is less than a preset threshold.

12. A method of registering and authenticating a user device for controlling a vehicle, the method comprising:

receiving, by a device registration and authentication apparatus included in the vehicle, an authentication request from the user device;

checking, by the device registration and authentication apparatus, whether the user device is registered in response to the received authentication request, and detecting whether a user of the user device has a FOB of the vehicle; and

performing a registration process of the user device which is set differently depending on whether the user has the FOB when the user device is not registered.

13. The method of claim 12 , wherein the performing of the registration process comprises:

performing a first registration process for registering the user device as a master device when it is detected that the user has the FOB and there is no other device previously registered as a master device, and

the performing of the first registration process comprises:

generating, by the device registration and authentication apparatus, random data for authentication of the user device, and transmitting the generated random data according to random data destination information included in the authentication request;

receiving, by the user device, an input according to the transmission of the random data, and transmitting the received input to the device registration and authentication apparatus; and

registering, by the device registration and authentication apparatus, the user device as a master device when the received input matches the generated random data.

14. The method of claim 12 , wherein the performing of the registration process comprises:

performing a second registration process for registering the user device as a general device or a temporary device when it is detected that the user does not have the FOB and there is another device registered as a master device, and

the performing of the second registration process comprises:

generating, by the device registration and authentication apparatus, random data for authentication of the user device, and transmitting the generated random data according to random data destination information of another device previously registered as the master device, the random data comprising first random data corresponding to registration as a general device and second random data corresponding to registration as a temporary device;

receiving, by the user device, an input according to the transmission of the random data, and transmitting the received input to the device registration and authentication apparatus; and

registering, by the device registration and authentication apparatus, the user device as a general device or a temporary device based on a comparison result between the received input and the generated first random data and second random data.

15. The method of claim 12 , wherein the performing of the registration process comprises:

performing a third registration process for registering the user device as a master device, a general device, or a temporary device when it is detected that the user has the FOB and there is another device previously registered as a master device, and

the performing of the third registration process comprises:

generating, by the device registration and authentication apparatus, random data for authentication of the user device, and transmitting the generated random data according to random data destination information of another device previously registered as the master device, the random data comprising first random data corresponding to registration as a general device, second random data corresponding to registration as a temporary device, and third random data corresponding to registration as a master device;
