An untraceable and server-independent RFID authentication scheme

RFID technology is an object identification technology which will become promising and ubiquitous attracting a lot of research attentions. But due to the open-medium nature of the radio communication and the simple structure of RFID tags, most RFID systems have to be tethered to a backend database and prone to tag tracing attacks which will lead to user privacy leakage. In this paper, we propose a RFID authentication scheme which enhances the mobility of the RFID systems by making backend database removable and protects user privacy by a label/ID sharing scheme.
