TITLE: SECURITY AND PRIVACY MEASUREMENT OF RFID-BASAED ELECTRONIC TOLL COLLECTION SYSTEMS

Abstract:

Electronic Toll Collection (ETC) systems in transportation have brought in tremendous economic benefits with traffic efficiency and accounting accuracy but, at the same time, leached out great threats to public security and privacy. Modern ETC systems mostly adopt Radio Frequency IDentification (RFID) technology for its advantages of not requiring a line of sight, a large set of unique identifiers, and capability of incorporating sensor and data process. However, RFID tags, called transponders in ETC systems, have limitations on computation resources and open accessing within proximity, vulnerable to attacks such as replay charging and location tracking.

This dissertation studies the security and privacy challenges unique to RFID-based ETC systems and offers counterattack measures for the entire system, focusing on the most vulnerable components currently not adequately covered by literature. By extending formal analysis of security and privacy protocols with security and privacy metrics of physical components, our approach merges the mathematical rigor for the logics of protocols with the practical values for the physics of environment. The toolbox to be developed from this research not only assists policy makers and system developers in transportation but also is applicable to other RFID-based applications for assess security and privacy products.
