RFID Authentication Protocol for Anti-Counterfeiting and Privacy Protection

RFID (radio frequency identification) is one of the most promising NFC (near field communication) technologies for pervasive and ubiquitous network societies in recent year. The main factor for more and more interests from both industry and academic institutes is due to the lower and lower costs, which may pose a threat to information security while RFID become part of our daily life because the lower cost, the weaker cryptographic algorithms provided by RFID tags. A feasible security mechanism for anti-counterfeiting and privacy protection is proposed that features mutual two-pass authentication and uses hash function and XOR operation to enhance the RFID tag´s security but still with low cost.
