RFID 安全读写机制的设计与实现

摘要

射频识别(RFID)技术是一项产生已久的应用技术,近年来在物流与供应链、身份
识别、安全门禁、电子购票、交通等领域得到了广泛的应用。由于目前并不存在着适
用于 RFID 系统的安全协议,安全隐患成为制约该技术大规模运用的重要因素。
由于 RFID 系统低成本要求的限制,当前许多成熟的密码算法无法适用于该系统
中。本文针对 RFID 系统的发展现状,采用了一种基于 TDES 算法的相互认证机制对
当前安全系统和协议进行改进。目前对密码算法的研究一般从速度优先的角度出发,
以消耗一定的资源为代价,但是对于 RFID 系统而言,如何减小芯片的面积是最主要
的问题。本文重点研究了 TDES 算法的架构,采用模块复用和串行数据传输的思想对
其进行面积优先的设计,使用工艺库进行综合仅需要约 1400 多门,符合
RFID 低成本的要求。同时采用相互认证机制实现了标签数字电路的设计,系统数据
传输基本能够满足机密性、完整性、可用性等要求,在当前的技术条件下具有极大的
现实意义。

RFID Security Solution and Implementation

ABSTRACT
Radio frequency identification (RFID) technology has been appeared for a long time,
which gains its popularity in a broad region such as automated identification and supply
chain applications, identification, entrance guard, electronic tickets, traffic etc. in recent
years. While the development inspiring, the security problem has emerged at the same time,
which brings some potential threat to the users.
For the strict limitation of low-cost requirement, the cipher arithmetic existed can’t be
used in the RFID system. In this paper, we develop a new security solution of
authentication based on the TDES arithmetic. Current research on the cipher arithmetic is
mainly about the speed of the circuit at the cost of some areas. But in this system, area is
the preferential factor. This paper has a study of the TDES arithmetic architecture, and
designs the circuit under the guiding ideology of module reuse and serial data transfer. As a
result, the new architecture needs only more than 1400 gates for implementation which
meet with the requirement of RFID system. Furthermore, plete the digital circuit
design for RFID bined with the mutual authentication. This method can meet the
security require such as confidentia
