SMART KEY AND CONTROLLING METHOD FOR THE SAME

A smart key comprises: a communication unit having an LF (low frequency) antenna receiving an LF signal; and a control unit determining an intensity of the LF signal and a direction vector. A control unit estimates a first position of the smart key based on the intensity of the LF signal and estimat...

Zusammenfassung:	A smart key comprises: a communication unit having an LF (low frequency) antenna receiving an LF signal; and a control unit determining an intensity of the LF signal and a direction vector. A control unit estimates a first position of the smart key based on the intensity of the LF signal and estimates a second position of the smart key based on the direction vector of the LF signal. Moreover, the control unit compares and analyzes the first position and the second position to determine a relay attack. 스마트키는 LF(Low Frequency)신호를 수신하는 LF안테나를 포함하는 통신부, LF신호의 세기 및 방향 벡터를 판단하는 제어부를 포함하되, 제어부는 LF신호의 세기에 기초하여 스마트키의 제 1 위치를 추정하고, LF신호의 방향 벡터에 기초하여 스마트키의 제 2 위치를 추정하고, 제 1 위치와 제 2 위치를 비교 분석하여 중계 공격을 판단할 수 있다.
