随着RFID(radio frequency identification)技术的广泛应用,引发的隐私威胁问题越来越突出.了解RFID隐私的内涵和常见攻击方法,掌握现有的RFID隐私保护技术,有助于减少RFID隐私信息的泄漏.从RFID技术的基本概念入手,全面分析了RFID隐私及隐私威胁,给出了RFID隐私分类方法;对RFID隐私中的跟踪攻击和罗列攻击两种攻击方法进行了深入探讨.在此基础上,对现有典型的RFID隐私防御方法进行了详细讨论.全面介绍了RFID隐私保护技术发展现状和动态,可作为开展RFID隐私保护技术研究工作的参考和借鉴.
This survey investigates different approaches proposed in the literature for addressing the privacy issues derived from the radio-frequency identification (RFID) and RFID based applications. The concep of RFID privacy and the vulnerability of privacy in RFID are both discussed. A detail discussion about the classification of RFID privacy is provided. Typical RFID privacy attacks, tracking attack and inventorying attack are also addressed. Finally, concentrating on the existing solutions for RFID privacy, and elaborates how the privacy in RFID and RFID based applications can be assured. The main goal of this survey is to give a concise classification of the most relevant privacy protection solutions applied to RFID privacy. For purpose of brevity and clarity, only the most relevant approaches are selected and addressed.
