Abstract:
A smart key authentication method for a vehicle remote key system that includes a smart key performing bi-directional communication with a vehicle to control the vehicle and a vehicle authentication module provided at the vehicle to authenticate the smart key is provided. The smart key authentication method includes generating, by the vehicle authentication module, a random number and sharing the random number with the smart key and performing a first authentication process based on the random number, and performing, by the vehicle authentication module, a second authentication process by comparing at least one location information value among an access point (AP) list, a satellite-based positioning sensor value, or a geomagnetic sensor value, which are respectively measured at the vehicle and at the smart key and determining whether or not to permit an authentication to the smart key.

Claim (Index 18):
The smart key authentication method for the vehicle remote key system according to  claim 17 , wherein\n the second authentication process is performed when the first authentication for the smart key is permitted in the first authentication process, and the vehicle authentication module checks whether a common AP ratio is greater than a predetermined value, the common AP ratio being a ratio of APs commonly included in the first AP list measured at the vehicle and the second AP list measured at the smart key among the first and second APs.
