RFID系统安全分析

Security Analysis of RFID Systems

无线射频识别(RFID)技术与条形码技术等相比,具有防水防磁、读取距离远、存储容量大、数据可加密等优点,目前己被广泛应用于交通、物流、医疗、食品安全等领域,但其作为物联网重要的感知设备因缺乏有效的安全机制而影响到物联网的应用与推广。文章从物理安全、通信安全和信息安全3个角度分析RFID系统安全问题及其解决方法。

RFID technologies have many intrinsic advantages, comparing to barcode technology and others, such as waterproof, antimagnetic, longer distance contact, bigger storage, data encryption. Recently, RFID technologies have been widely used in the area of transportation, logistics, medical treatment, food safety guarantee technology. However, as important sensing equipments, RFID are influenced to use more widely owing to security mechanism deficiency. In this paper, we analysis RFID system security problems and present corresponding solvers.
