Abstract: Aiming at the present problems existing in security of RFID protocol and high spatial and temporal complexity, a new communication protocol which uses an efficient NTRU encryption for RFID tripartite certification is proposed. Based on the tags, readers and servers tripartite certified communication model is built. Combined with the actual security threats, safety and performance of the proposed protocol are discussed. Compared with other relevant protocols, the protocol has provided improved security in mutual authentication and good performance.
