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 19):
The smart key authentication method for the vehicle remote key system according to  claim 17 , wherein the smart key generates a first random number, and when smart key authentication information containing the first random number is transmitted to the vehicle authentication module, the smart key receives a response signal containing the first random number and a second random number generated at the vehicle authentication module from the vehicle authentication module, and\n wherein the smart key verifies the response signal with the first random number, and, when the response signal is verified, the smart key extracts smart key location information including an AP list, generates an authentication request signal containing the smart key location information and the second random number received from the vehicle authentication module, and transmits the authentication request signal to the vehicle authentication module.
