移动射频识别(RFID)系统独有的无线传输、信号广播以及前向信道与后向信道的非对称性,使得移动RFID系统面临着诸多安全问题。针对这些问题,分析了现有的几个典型的RFID安全协议的特点和缺陷,提出一种新的移动RFID双向认证协议,实现了标签、读写器与后端数据库服务器三者的双向认证,在实现上仅使用Hash和异或运算,降低了标签的计算复杂性,并对其安全性进行了分析和GNY逻辑证明。
Abstract：Based on wireless communication,signal broadcasting,and non-symmetry between the forward channel and the backward channel,mobile RFID systems are confronted with many security challenges. To address these issues,the features and issues pertinent to several current typical RFID security protocols are analyzed. A new mutual authentication protocol for mobile RFID is proposed.It can achieve mutual authentication between tags,readers and back-end database server. Its implementation only involves Hash and exclusive XOR operations,which reduces computing complexity. The security of the proposed protocol is analyzed. GNY logic is applied to prove its correctness.
