Analysis of Threats and Countermeasures for Odomter Protection

초록

In the used car market, mileage is one of the principal criteria used for evaluating the overall condition of a vehicle. For this reason, mileage fraud continues to occur. Futhermore, the number of malicious brokers who obtain a monetary advantage by manipulating vehicle mileage is increasing. As many used cars with manipulated mileage are sold each year, buyers have suffered significant monetary damages. Although the number of mileage fraud reports has remained steady, governments and OEMs have no technical countermeasures to prevent it, beyond asking used car buyers to pay careful attention when purchasing used cars. This paper classifies odometer system architectures according to the types of sensors and controllers used to measure and transmit vehicle speed, and defines the assets to be protected in a secured odometer. Based on this classification, we analyze potential security threats related to mileage fraud. Finally, we propose realistic security requirements to prevent mileage fraud, within a resource constrained automotive controller environment.
