Research on the Security Issues of RFID-Based Supply Chain

Safety is one of the most important issues of communication systems, especially for wireless communication systems which use insecure wireless channel to communicate with each other. In RFID systems, data transmission between tags and readers or sometimes even data transmission between readers and back-end database uses the wireless channel. There are some risks inherent in RFID systems, such as counterfeit RFID tag attacks, reply attacks, eavesdropping attacks, etc. Therefore, how to ensure the security of RFID systems is particularly important. Unlike common RFID systems, the security issues of RFID-based supply chain also involve ownership transfer. In this paper, these security issues are researched and analyzed in detail and the key point is point out clearly.
