Radio Frequency IDentification (RFID) is an automatic identification technology to remotely store and retrieve data, and has been used in various application fields. Wireless readers are used more and more widespread, it brings higher design requirements for RFID protocols. Based on wireless communication, signal broadcasting, and non-symmetry between the forward channel and the backward channel, RFID systems are confronted with many security problems. Due to strictly limited calculation resources, small storage capacity and faint power supply of low-cost tags, it is difficult to apply an ordinary and complicated but safe cryptographic algorithm to a RFID system and these factors are hindering the rapid spread of this technology.
