1. A method for authenticating a first vehicle to a second vehicle, the method comprising:
- receiving a first packet including position information of the second vehicle and first identity information from the second vehicle through a first communication scheme;
receiving a second packet including the first identity information from the second vehicle through a second communication scheme different from the first communication scheme;
acquiring first distance information about a distance between the first vehicle and the second vehicle based on the position information of the second vehicle;
acquiring second distance information about a distance between the first vehicle and the second vehicle based on an interval between a first time point when the first packet is received and a second time point when the second packet is received and a transmission speed of the second communication scheme; and
authenticating the second vehicle based on the first distance information and the second distance information.

13. A first vehicle comprising:
-
a first communication interface comprising communication circuitry configured to receive a first packet including position information of a second vehicle and first identity information from the second vehicle through a first communication scheme; a second communication interface comprising communication circuitry configured to receive a second packet including the first identity information from the second vehicle through a second communication scheme different from the first communication scheme; and a processor configured to acquire first distance information about a distance between the first vehicle and the second vehicle based on the position information of the second vehicle, to acquire second distance information about a distance between the first vehicle and the second vehicle based on an interval between a first time point when the first packet is received and a second time point when the second packet is received and a transmission speed of the second communication scheme, and to authenticate the second vehicle based on the first distance information and the second distance information. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A computer program product comprising a non-transitory computer-readable storage medium having stored thereon instructions which when executed configure a first vehicle to:
-
receive a first packet including position information of a second vehicle and first identity information from the second vehicle through a first communication scheme; receive a second packet including the first identity information from the second vehicle through a second communication scheme different from the first communication scheme; acquire first distance information about a distance between the first vehicle and the second vehicle based on the position information of the second vehicle; acquire second distance information about a distance between the first vehicle and the second vehicle based on an interval between a first time point when the first packet is received and a second time point when the second packet is received and a transmission speed of the second communication scheme; and authenticate the second vehicle based on the first distance information and the second distance information.
