摘要: 为降低无线射频识别(RFID)的标签成本,解决后台数据库与标签间更新不同步的问题,提出一种基于异或运算的RFID双向认证协议。通过改变数据库与标签更新次序,实现标签和数据库之间的同步更新,在标签中仅使用异或运算和随机数生成器,使其适用于低成本RFID系统。实验结果表明,该协议的运算量、标签硬件成本开销较小,能保证数据传输安全。

Abstract: In order to overcome the high complexity of tag and resynchronization between tag and database, a new mutual authentication protocol is proposed based on Exclusive OR(XOR) operation. The new protocol can deal with the synchronization of data update by changing the update order. As only XOR and random number generator are required to be computed by tags, it is very suitable for low-cost Radio Frequency Identification(RFID) system compared with hash-based authentication protocols. Experimental results show that this protocol can guarantee the safety of data transmission, and the hardware cost and computation spending is low.

Key words: Radio Frequency Identification(RFID), mutual authentication protocol, Exclusive OR(XOR), synchronous update, low- cost, security
