Super Lightweight Mobile RFID Authentication Protocol for Bit Replacement Operation

Abstract

In the traditional RFID system, the secure wired channel communication is used between the reader and the server, and the new mobile RFID system is different from the traditional RFID system. The reader and the server communicate based on the wireless channel. This makes authentication protocols applicable to traditional RFID systems not applicable to mobile RFID systems. To solve this defect, a two-way authentication protocol MSB is proposed for ultra-lightweight mobile radio frequency identification system based on bit replacement operation. MSB (most significant bit) encrypts information based on bitwise operations, and the amount of computation of the communication entity is reduced. Tags, readers, and servers first authenticate and then communicate. MSB can be resistant to common attacks. The security analysis of the protocol shows that the protocol has high security attributes, and the performance analysis of the protocol shows that the protocol has the characteristics of low calculation volume. The formal analysis of the protocol is given based on GNY logic.
