中文摘要：

探究了当前RFID安全认证协议中较少涉及的标签编组领域,分析了典型标签编组协议Yoking Proof的安全问题,提出了基于标签编组的RFID相互认证协议（MATG）。MATG协议将同类标签进行编组,在协议相互认证过程中,阅读器能选择特定的标签组,并在一次协议过程中自动完成对组中所有标签的识别。对所提出协议的安全性进行了分析和BAN逻辑证明,并用C语言编程进行了重放攻击仿真。理论分析和仿真结果显示,MATG协议克服了Yoking Proof协议的缺陷,提高了成组商品标签的识别效率和安全性。

英文摘要：

Explore the tag grouping field less involved in current RFID security authentication protocol, Yoking Proof protocol＇ s security problems are analyzed. An RFID Mutual Authentication protocol based on Tag Grouping （MATG） was proposed. The same tags are grouped by MATG, reader can select a group of tags in the mutual authentication process, and then identify targets automatically in a protocol processing. Safety of the proposed protocol is analyzed and proved with the BAN logic, and then attack simulation is performed using C programming language. Theoretic analysis and simulation results show that MATG protocol overcomes Yoking Proof protocol＇ s shortcomings and improves working efficiency and safety when dealing with a group of tags.
