Abstract
The present invention relates to a method for preventing a relay-attack on a smart key system, and in particular, provides an advantage of preventing a vehicle and equipment stored inside the vehicle from being stolen by using predetermined information transmitted and received when the SMK UNIT of the vehicle and a FOB Key wirelessly communicate with each other and enabling a holder of the FOB Key to make the relay-attack once the holder secures visibility from the vehicle.
