An Efficient and Private RFID Authentication Protocol Supporting Ownership Transfer

Radio Frequency IDentification based systems, which are the most famous example of ubiquitous networks, are getting pervasively deployed in many daily life applications where privacy sensitivity is entrusted to tag or server. In some applications, ownership transfer of RFID labels is another significant requirement. Specifically, the owner of RFID tags could be required to change several times during its lifetime. During the transfer, new owner first obtains necessary private information from the old owner, with these information. Then, the authors take over tag identification and authorization so as to have secure communication with tags. Security and privacy are major issue in the presence of malicious adversary.
