T-Box: Tamper-resistant vehicle data collection system for a networked digital tachograph

With the widespread deployment of digital tachograph, an ability to record the driving data in a tamper-resistant manner has become a critical issue. The installation of the digital tachograph has been mandatory for all business vehicles in Korea since 2012. As its next step, a networked digital tachograph has been developed for real-time monitoring of the driving time, breaks, as well as rest periods undertaken by a driver. In this paper, we propose a tamper-resistant logging system for the networked digital tachograph, called T-Box. To provide the tamper-resistant logging, we devised a TPM-based logging mechanism in which even the drivers cannot modify or falsify the driving data.
