RFID安全与隐私威胁

Privacy and security threats in RFID

RFID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。随着标签制造成本的下降，RFID技术大规模应用已成定局，但人们对RFID普及应用所遭受的安全与隐私威胁还不够重视，甚至认为资源严重受限的标签会免于病毒攻击。该文分析了RFID技术应用中的一般安全与隐私威胁及其系统的安伞缺陷．着雷讨论基于RFID的入侵、病毒原理和移动RFID的隐私威胁。

Radio frequency identification （RFID） technology is used to identify objects and users, and automatically takes advantage of contextual information such as users location. This technology has been applied to many fields such as retail and supply chain. At recent, there are increasing number of concerns, and even some resistance, related to user tracking and profiling and other security concerns using RFID technology. Therefore, this paper surveys recent technical research on the problems of privacy and security in various RFID applications and brings up some ideas in mobile RFID and RFID virus, worm and so on.
