A Radio-Frequency-Identification (RFID) tag is a small and cheap device which is combined in IC chip and an antenna for radio communications. The RFID tag is used for management of goods and used as a substitute for a bar code. However, RFID system may infringe on a consumer’s privacy because it has a strong tracing ability. In this paper, we propose a key change scheme which can prevent previous owner from reading the RFID tag after changing its owner. By using our scheme, previous owner cannot read and trace ID information on the RFID tag. Moreover it is possible to combine other privacy protection scheme with our scheme because our scheme uses only symmetric key cryptography.
