Side Channel Analysis: A New Perspective for Vehicle Intrusion Detection System

This is an online IEEE VTS Distinguished Lecturer seminar.

Date: 12 Apr 2022

Time: 06:00 PM to 07:00 PM

Presenter: Dr. Jiajia Liu


Intelligent connected vehicles (ICVs) have become the mainstream in the development of automobile industry. Many emerging technologies have been proposed to provide users with comfortable and convenient driving experience. Note that some of the communication interfaces are vulnerable and can be easily attacked. Although many malicious attacks can be carried out in various ways, their final step must be in the in-vehicle network, i.e., the controller area network (CAN) bus. In order to protect the security of CAN bus, it is of great importance to design an intrusion detection system (IDS) which can monitor the message transmission in real time. There are various defense mechanisms that have been proposed, but they cannot meet the high security requirements of safety-critical ECUs against in-vehicle network attacks. In this talk, we propose three vehicle IDS solutions from the perspective of side channel analysis, based on the unique voltage characteristics of each ECU, the clock skew of each ECU, and the correlation among data frames in CAN bus. They neither occupy the bandwidth and computing resources of CAN bus, nor need to modify the original CAN protocol. They can not only accurately detect malicious attacks, but also identify the attack source with high precision, thus realizing timely discovery and isolation of vehicle attacks.
