Privacy Enhanced Authentication Protocol for RFID Tag System Security


Sang-Soo Yeo, Jin Kwak


Vol. 7  No. 9  pp. 1-6


Radio Frequency Identification (RFID) system is now becoming widely accepted for many ubiquitous computing applications. However, RFID system has some privacy problems. Therefore, many researches results related to security and privacy in RFID system. However, we cannot choose anything among them for applying to the current RFID system. Most of them require either of high-cost hardware specification or giving up potential convenience of consumers. In this paper, we propose a simple privacy protection scheme that can be used for the current existing RFID system such as ISO 18000-6 type C. We modify this standard tag identification protocol slightly and introduce a light-weight proxy device for privacy enhancing.
