An Enhanced RFID Authentication Protocol

RFID is a technology for automatic identification and tracking, which as a substitute for barcodes is an important part of The Internet of Things. However, since the inherent characteristic that the information transmitted in the open air can easily be intercepted and eavesdropped, the security and privacy is an important issue for RFID communication system. Recently, Khor et al. presented an electronic fingerprint-based RFID authentication protocol which conforms to the EPC Class-1 Generation-2, however, we find it remain exist some security weakness about Khor et al.'s protocol. Then, we propose an enhanced protocol to remedy these weaknesses.
