Abstract

Due to the very limited computing resource, storing space and electric power supply of tag, it is a great challenge for us to design a practical RFID protocol which is security, efficient and can be used in the low-cost tag. In 2007, He et al. proposed an authentication and key agreement protocol which is used in the process of communication between the low-cost tag and reader. They also proved the security of the protocol through the extended strand space model. This paper presents a more efficient authentication and key agreement protocol for RFID system than He et al.'s protocol. Compare with He et al.'s protocol, the proposed protocol reduces the computational costs as well as protocol communication rounds to agree a shared session key between the reader and the tag.
