Abstract
A smart key for a vehicle includes: a communication unit including a low frequency (LF) antenna which receives an LF signal; and a control unit determining a strength and a direction vector of the LF signal. The control unit estimates a first location of the smart key based on the strength of the LF signal, estimates a second location of the smart key based on the direction vector of the LF signal, and determines a presence of a relay attack by analyzing the first location and the second location and comparing the first location with the second location.
