基于RFID的物联网安全性研究

Internet of Things Security Research Based on RFID

通过物联网的研究历史和现状进行了总结和分析,阐述和分析物联网以及RFID的组成和工作原理,并根据这些内容对现有技术中存在的一些安全隐私问题进行重点研究。针对关于RFID的攻击手段,分别介绍基于物理机制的解决方案以及基于密码技术的解决方案。为了满足RFID系统对安全隐私方面的需求,并改善原有安全协议中的缺陷,提出一个基于时间戳的挑战——应答模式的双向认证协议。

Security threats restricted the development of the Internet of Things. This paper summarizes the historical and present situation of the Internet of Things, analyses the structure and working principle of RFID, and lays emphasis on the research of the privacy problems caused by existing technologies. Two kinds of methods, based on the physical mechanism and password technology, used to solve the attacks of RFID are introduced. An two-way authentication protocol based on timestamp is proposed which can meet the security requirements of RFID, and improve the defects of present security protocols.
