Research And Improvement Of The Grouping-proof Protocol For RFID Tags In Internet Of Things

RFID as the core of Internet of Things is a new auto identification technology. Itis regarded as one of most promising information technology. And it can be widely usedin many fields such as production, traffic, logistics, security and national defense.The security and privacy are the key factor whether RFID technology can becommercial. RFID is wireless, has strong anti-interference capacity and can identifymultiple targets compared with Barcode, Magnetic and IC card. Otherwise, it also bringabout new security communication problem. RFID label can be tracked easily becauseof wireless feather. And the customer will be placed under new security threat. On theother hand, group security certification will be research again for the function ofidentifying multiple targets.In this article the characteristics and security of RFID in the Internet of Thingsare analyzed and summarized. And the author made the requirement analysis anddesigned privacy protection for RFID grouping-proof protocol. Then the author studiedthe protocol created by Zhangzhong seriously, analyzed the advantage and disadvantageof RFID, and showed own design idea. And the author issued a new grouping-proofprotocol about low cost synchronized RFID key label. Multiple tags certification in thetags group will be solved by this protocol. So the author analyzed the new protocolfrom function, security, efficiency and used lightweight encryption algorithm. Overall,the efficiency of identification is improved and the cost of communication is reducedby the new protocol compared with safe RFID protocol based on UC grouping-proof inInternet of Things listed by Literature [12].
