Theoretical analysis of RFID security protocols

Radio Frequency Identification (RFID) is a system that transmits an entity´s identity wirelessly using radio waves in the form of a unique serial number. RFID systems are broadly applied in various applications. The remarkable increase in the use of RFID technology has resulted in a number of security and privacy issues. Moreover, most previous security schemes suffer from the lack of a global standard secure communication and the time-consuming computational process of the necessary database activities. This paper focuses on the problems faced by RFID protocols attempting to raise security and privacy. Therefore, several criteria of RFID protocols will be compared and discussed on some chosen security protocols; including conformity to the EPCglobal C1-G2 standard, ability to implement on low-cost tags, anonymity, privacy, tracking, forward security, DoS attack, and impersonation attack.
