Radio Frequency Identification (RFID) systems can uniquely identify objects, and have many applications. However, security issues pose significant challenges on these systems due to computational and communicational limitation of low cost RFID tags. This motivates us to provide a discussion on security issues in RFID systems with solutions and enhancements in this article.
Radio frequency identification (RFID) is a way to identify a person/object using a radio frequency transmission from an embedded transponder, known as tag. An RFID reader (transceiver) is used to scan the area for RFID tags by generating an electromagnetic field and then to collect the information broadcasted by the tags, including a serial number, model number, color, place of assembly, and other data.1 A RFID tag can take one of three forms: passive where the tag relies upon a current generated by incoming radio as its power source, semi-passive where a tag possesses a battery but is otherwise passive, and active where a tag has its own power supply...
