摘要：It was proposed a secure group ownership transfer protocol for tags in RFID system to transfer the ownership of multiple tags simultaneously. Old owner executes authentication and updates secrets of a group of tags. Afterwards, it sends the secrets updated to new owner in a secure way. New owner also implements authentication and update procedure with tags. The protocol was analyzed by using GNY logic. It provides mutual authentication between tags and owners. It resists replay attack, man-in-the-middle attack and desynchronization attack. It also protects forward security, backward security and user's location privacy. Our protocol was implemented and simulated. We obtained experimental data including time cost by tag in the procedure of ownership transfer. It infers that our protocol has much less time cost by tag compared with other protocols.
