Strong and robust RFID authentication enabling perfect ownership transfer

摘要: RFID technology arouses great interests from both its advocates and opponents because of the promising but privacy-threatening nature low-cost tags. A main privacy concern in systems results clandestine scanning through which an adversary could conduct silent tracking inventorying persons carrying tagged objects. Thus, most important security requirement designing protocols is to ensure untraceability tags by unauthorized parties (even with knowledge a tag secret due no physical tags). Previous work this direction mainly focuses on backward untraceability, requiring that compromise should not help identify past communication transcripts. However, paper, we argue forward i.e., future events even current secret, be considered as equally or more property protocol designs. Furthermore, may often change hands during their lifetime thus problem ownership transfer dealt another key issue problems; once transferred party, old owner able read any more. It rather obvious complete possible only if some degree provided. We propose strong robust authentication satisfying enabling ownership.
