Abstract: In the mobile RFID system, the channel between reader and server is usually insecure, therefore the security and performance of current mobile RFID authentication protocol is analyzed. The mobile RFID security privacy model is established. Based on the model, a mutual authentication protocol, which can resist impersonation attack and desynchronization attack, as well as provide the forward secrecy protection, is proposed. It is compatible with EPC Class-1 Generation-2 low-cost tag system. Security proof and performance analysis show that the protocol not only achieves the designing purpose, but also can be applied to the large scale mobile RFID system with low-cost tag.
