A secure access control protocol of RFID tags based on EPC C1G2

The weak security capability of RFID systems has greatly hindered the development of RFID applications in the Internet of things. EPC C1G2 has many security risks, such as the plain-text transmission of tag information, the easily compromised passwords, and the shortage of tag authentication. Some studies on designing security protocols for RFID tags either do not conform to EPC C1G1 or suffer from security flaws. After analyzing the existing security protocols, this paper designs a secure access control protocol of RFID tags. The analysis results have showed that the proposed protocol meet the security requirements of RFID systems based on EPC C1G2.
