Abstract
This paper proposes a new security protocol with satisfying the lightweight requirements of the security of RFID system---A Minimalist Mutual Authentication Protocol for RFID System Based on EPC C1G2 Standard. The scheme makes sufficiently use of the limited resources of RFID system to encrypt, decrypt and implement mutual authentication between readers and tags, Then the paper gives qualitative analysis against various security attacks and BAN logic analysis of the security of the protocol. The results demonstrate that the protocol can effectively solve the security problem of RFID system based on C1G2 standard.
