摘　　要：针对可扩展射频标签(RFID)认证鉴权子协议P1存储代价与寻签查找效率的矛盾和密钥更新子协议P2的非同步攻击缺陷,提出了一种改进的RFID轻量级、可扩展、自同步所有权变更协议(LSDARP).该协议采用滑动窗口机制,仅存储和维护标签新旧相邻特征值,既降低了存储代价又可避免产生特征值组耗尽后的寻签效率退化问题,在遭受连续非同步攻击后自行恢复同步.在存储代价、计算复杂度、后向安全、抵御非同步攻击和Tag Killing攻击等方面,LSDARP协议比P1、P2协议更优.Aiming at the conflict of the storage cost, the update frequency in P1and the de-synchronizing defect in P2, an improved scalable radio frequency identification tag （RFID） ownership transfer protocol- lightweight scalable desynchronizing attack resistant protocol （LSDARP） was proposed. By the mecha- nism of sliding windows, the scheme only stores the tag＇ s old and new adjacent eigenvalues to reduce the storage cost and avoid search efficiency degeneration when a group of eigenvalues was used out. It can be also re-synchronized when suffering de-synchronizing attacks continuously. Comparative analysis shows that LSDARP performs very well in aspects of the storage cost, computational complexity, backward secu- rity, de-synchronizing attack resistant and Tag Killing resistant.
