Two-way Authentication Protocol Based on SM2 and Zero Knowledge for Radio Frequency Identification

Abstract

To ensure the wireless communication security of the reader and tag in the Radio Frequency Identification(RFID) system,based on domestic public key cryptography algorithm SM2 and introducing zero knowledge proof idea,this paper proposes a two-way authentication protocol.Then security and efficiency analysis are given.The formal analysis is made by using BAN logic.Results show that the two-way authentication of the proposed protocol is completed in the case that reader and tag just interact twice,and has high safety and communication efficiency.
