RFID Authentication and Communication Protocol Based on the Dynamic Active Tag ID and Key

Abstract

The reliability of Radio Frequency Identification (RFID) mechanism is disturbed by illegal tracking and information intercepted.The paper proposed a new active RFID authentication protocol based on the dynamic tag ID and encryption key,which transforms the tag ID using chaotic transformation during authentication and communication between the reader and tags,and realizes mutual authentication of the reader and tags.Through the analysis of security, the protocol not only can ensure the integrity, fresh and confidentiality of data, but also can effectively prevent illegal tracking labels and replay attack.
