基于椭圆曲线密码的 RFID 安全协议
摘
要
无线射频识别(radio frequency identification,简称 RFID)技术是
从上世纪六、七十年代兴起的一项非接触式自动识别技术。RFID 技术
目前被广泛应用于工业生产和日常生活的各个方面,但其在应用中还存
在着不可忽视的隐患——缺乏安全机制,因此无法有效保护 RFID 标签
中的数据信息。当前,RFID 的安全性已经成为制约其大规模运用的重
要因素。本文对 RFID 系统存在的安全问题和隐私问题进行了详细阐述,
进而对无线射频系统现有的安全协议进行了评估分析,指出其不足之
处。并在此基础上提出了基于椭圆曲线密码的安全机制,用以保护 RFID
标签与读写器之间的数据交换,还对利用该安全机制所构造的协议进行
了全面的分析。

THE SECURITY PROTOCOL OF RFID
BASED ON ELLIPTIC CURVE CRYPTOGRAPHY
ABSTRACT
Radio frequency identification (RFID) technology is an untouched
auto-identification technology which had been raised in 60’s-70’s last
century. Now RFID technology is used in a lot of facets of industry
manufacture and everyday life, but there is a hidden trouble which can’t be
ignored in RFID system, it is lack of security mechanism, so RFID is not
able to protect its date effectively. Currently security of RFID has been an
important factor which restricts RFID used on a large scale. This article
expatiates on existent security problem and privacy problem of RFID system
in detail, at the same time, analyzes and evaluates the existing security
protocols which are used in RFID system, then points out its shortages.
Ground on these works, my article affords a security mechanism based on
elliptic curve cryptography, the data changed between RFID tag and reader
can be protected by this mechanism. My article also analyzes the protocol
which is constructed by the security mechanism in the round.
