Secure and efficient RFID mutual authentication protocol

Radio Frequency IDentification (RFID) is an automatic technology for identification of objects in the open system environment. The technology currently offers a wide range of application prospects in logistics, manufacturing, retail and many other areas. Thus how to design secure and efficient authentication protocols for RFID systems is a fundamental issue. In this paper, a novel RFID mutual authentication protocol that utilized a keyed hash function and synchronized information was proposed. We described the protocol in detail and discussed the related protocols. The results show our protocol has the advantages in security and efficiency.
