射频识别技术安全问题研究

Research on security problem of radio frequency identification

RFID（Radio Frequency Identification）是一种利用射频信号自动识别目标对象并获取相关信息的技术，已经在各个领域内显示出其强大的优越性，随着标签制造成本的下降，RFID应用将更加广泛，但安全和隐私问题不容忽视。该文分析了当前RFID的安全与隐私威胁状况，提出并比较相关保护方案，最后分析RFID的系统缺陷、缓冲器溢出、代码植入、蠕虫等RFID系统可能会遇到的攻击。

Radio frequency identification （RFID） technology is used to identify objects and automatically takes advantage of contextual information, which has exhibited great advantages in every application area. As long as the cost decrease of making tag, the application of RFID technology will be more broadly and make life more convenient obviously, but privacy and security threats can be concerned with the consumer. Therefore, this paper surveys recent privacy and security threats of RFID, brings up some protection schemes, and discusses system limitation, buffer overflow, SQL injection, worm attack of RFID system.
