物联网RFID系统安全防护浅析

Analysis on security protection of RFID system in Internet of Things

随着物联网技术的发展,物联网安全问题受到了广泛的关注。作为物联网关键技术之一,无线射频RFID技术正面临着严重的安全威胁。本文分别对物联网体系结构、RFID系统组成和工作原理进行了阐述,分析了RFID系统在数据保密性、完整性、可用性以及身份真实性方面所面临的安全问题,最后从物理措施和认证协议两方面总结了具体的防范措施。

With the development of Internet of things technology, the security of Internet of things has been attracted extensive attention.As one of the key technologies of the Internet of things, the RFID(radio frequency Identification) is facing a serious security threat. In this paper, the structure of the Internet of things and the composition and working principle of RFID system are discussed first. And then we analyze the security problems in the aspects of data security, integrity, availability and authenticity of RFID system. Finally, the concrete precautions are summarized from two aspects of the physical measures and the authentication protocol.
