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 9):
A vehicle remote key system comprising:\n a smart key configured to generate a first random number, when smart key authentication information containing the first random number is transmitted to a vehicle authentication module provided at a vehicle, receiving a response signal containing the first random number and a second random number generated by the vehicle authentication module, verifying the response signal with the first random number, when the response signal is verified, extracting smart key location information including at least one of an AP list, a satellite-based positioning sensor value, and a geomagnetic sensor value, generating an authentication request signal containing the smart key location information and the second random number received from the vehicle authentication module, and transmitting the authentication request signal to the vehicle authentication module; and the vehicle authentication module configured to perform a first authentication process by comparing the second random number contained in the authentication request signal with the second random number generated by the vehicle authentication module, when a first authentication for the smart key is permitted according to the first authentication process, extracting vehicle location information corresponding to the smart key location information, and performing a second authentication process by comparing the vehicle location information with the smart key location information contained in the authentication request signal, determining whether or not to permit the authentication to the smart key.
