THE USE OF SECURE SYMMENTRIC AUTHENTICATION FOR RFID TAGS

Radio frequency identification system (RFID) is an automatic technology and aids machines or computers to identify objects, record metadata or control individual target through radio waves. Connecting RFID reader to the terminal of internet, the readers can identify track and monitor the objects attached with tags globally, automatically and in real time, if needed. The advantages of using RFID technology is growing tremendously and is gaining much attention as is seen by an increase in its deployment, such as object tracking and monitoring supply chain management and personalized information services. Numerous authentication protocols for RFID systems were proposed in an attempt to prevent unauthorized tracking and monitoring, impersonation or cloning and information leakage. Many of these attempts fail to enforce anonymity and order only weak authentication and some fail under denial of service. With a small introduction to RFID tags this paper enhances passive RFID (Radio Frequency Identification) tags with cryptographically secure authentication starting with a short introduction into common RFID systems, we demonstrate vulnerabilities of current RFID systems and explain how application of an authentication mechanism can solve them. Further-more we explain how authentication protocols work and how they can be included in the RFID protocol standard ISO-18000
