The RFID technique is spot-lighted as the main technology in Ubiquitous era to identify the information of the objects. Because the communication on the RFID system is operated in the wireless, the secure and privacy problems always exist. In this paper, we propose mutual authentication protocol which is good for the low-cost tags based on ECC and AES. By using AES, the protocol could minimize tag resources. Even if the shared key might be opened to the world, the actual tag IDs encrypted by ECC are secure. We verified the security of the protocol using AVISPA.
