RELAY ATTACK PREVENTION METHOD FOR SMART KEY SYSTEM FOR VEHICLE

摘要

The present invention relates to a relay attack prevention method for a smart key system for a vehicle. Particularly, an RF signal such as a searching signal (RF signal) transmitted from a SMK Unit of the vehicle and a second reaction signal (RF signal) transmitted from a FOB key in reaction to the searching signal bidirectionally communicates to determine whether the FOB key approaches and is separated and whether the relay attacks. Here, a function operation part of the vehicle may be controlled only when the FOB key approaches to the vehicle, and thus a more powerful invasion prevention system against third party may be provided.;COPYRIGHT KIPO 2015
