Well scalability is an important requirement for RFID systems, how to alleviate workload of the backend server so as to deal with large scale tags becomes a challenging research object. Index inner table used in RFID reader can efficiently utilize calculation capacity and storage space of a reader to construct a filter which can sift authentication applications from tags, thus, alleviate workload of the backend server and resist replay attack from an adversary. In this paper, revised index inner table is proposed, then modified structure and filter algorithm, update and sorting algorithm, eraser algorithm of index inner table can be applied in different filter modes according to various factual application environments.
