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 8):
The smart key authentication method for the vehicle remote key system according to  claim 6 , wherein\n when the second authentication process is performed by comparing the location information of the satellite-based positioning sensor value and the geomagnetic sensor value, the vehicle authentication module checks whether a sum of a value obtained by multiplying a difference between the satellite-based positioning sensor value measured at the vehicle and the satellite-based positioning sensor value measured at the smart key by a predetermined constant, and a value obtained by multiplying a difference between the geomagnetic sensor value measured at the vehicle and a geomagnetic sensor value measured at the smart key by a predetermined constant is smaller than a predetermined value.
