Abstract

A method for detecting intrusion into an in-vehicle network using an intrusion detection system (IDS) of a vehicle includes: receiving messages of the in-vehicle network in a preset cycle, calculating a current count value per message of the received messages, receiving operation state information of the vehicle when the cycle starts, determining a normal count value per message corresponding to the operation state information, calculating a linearly approximated relative distance function per message using the current count value and the normal count value, and determining whether an intrusion state occurs by comparing the calculated linearly approximated relative distance function per message to a preset threshold value.

Description

technical field [0001] The present invention relates to an intrusion detection system (IDS: intrusion detection system) for preventing intrusion of an in-vehicle network and a method for controlling the same. Background technique [0002] Recently, functions of electronic control units (ECU: electronic control units) installed in vehicles have been significantly increased. At the same time, the network can be accessed from the vehicle via wireless network. However, as described above, if the vehicle is connected to a wireless communication network and a peripheral network environment, intrusion into the ECU of the vehicle can be remotely achieved through the network. A malfunction of a vehicle due to external intrusion may be fatal to a driver or a passenger of the vehicle. [0003] The problem is that vehicles that have been produced have no or fewer solutions to the above problems. Although various IDS techniques have been proposed, these techniques cannot be easily imp...
