Low-cost Authentication Protocol of the RFID System Using Partial ID

Previous RFID techniques, cause serious privacy infringements such as excessive information exposure and user's location information tracking due to the wireless characteristics and the limitation of RFID systems. Especially the information security problem of read only tag has been solved by physical method. In this paper, we propose a low-cost mutual authentication protocol which can be adapted to read-only tag and is secure to several attacks using XOR computation and Partial ID concept. The proposed protocol is secure against reply attacking, eavesdropping, spoofing attacking and location tracking; therefore it can be used to support secure and low cost RFID system
