A method and an apparatus for preventing hacking of a wireless signal for a vehicle are disclosed. According to an aspect of the present invention, a vehicle wireless signal hacking prevention method comprises the steps of: sequentially transmitting, by a smart key (SMK) ECU, first and second low frequency (LF) signals of different amplitudes to a FOB key through a plurality of antennas installed inside a vehicle; detecting, by the FOB key, first and second received signal strength indicators (RSSIs) of the first and second LF signals received from each of the plurality of antennas, respectively, and transmitting the first and second RSSIs of each antenna to the SMK ECU; and comparing, by the SMK ECU, the first and second RSSIs of each antenna, selecting an antenna having a maximum value, and determining whether a wireless signal is hacked using the first and second RSSIs of the selected antenna.

    차량용 무선신호 해킹 방지 방법 및 장치가 개시된다. 본 발명의 일 측면에 따른 차량용 무선신호 해킹 방지 방법은, SMK(Smart Key) ECU가 차량 내부에 설치되는 복수의 안테나 각각을 통해 서로 다른 진폭의 제1 및 제2 LF(Low Frequency) 신호를 순차적으로 포브키(FOB Key)로 송신하는 단계, 상기 포브키가 상기 복수의 안테나 각각으로부터 수신한 제1 및 제2 LF 신호의 제1 및 제2 RSSI(Received signal strength indicator)를 각각 검출하고, 각 안테나의 제1 및 제2 RSSI를 상기 SMK ECU로 송신하는 단계, 상기 SMK ECU가 각 안테나의 제1 및 제2 RSSI를 비교하여 최대 값을 가지는 안테나를 선택하고, 상기 선택된 안테나의 제1 및 제2 RSSI를 이용하여 무선신호의 해킹 여부를 판단하는 단계를 포함한다.
