RFID enabled traceability networks: a survey

The emergence of radio frequency identification (RFID) technology brings significant social and economic benefits. As a non line of sight technology, RFID provides an effective way to record movements of objects within a networked RFID system formed by a set of distributed and collaborating parties. A trail of such recorded movements is the foundation for enabling traceability applications. While traceability is a critical aspect of majority of RFID applications, realizing traceability for these applications brings many fundamental research and development issues. In this paper, we assess the requirements for developing traceability applications that use networked RFID technology at their core. We propose a set of criteria for analyzing and comparing the current existing techniques including system architectures and data models. We also outline some research opportunities in the design and development of traceability applications.     

A minimum disclosure approach to authentication and privacy in RFID systems

In this paper we present a novel approach to authentication and privacy in RFID systems based on the minimum disclosure property and in conformance to EPC Class-1 Gen-2 specifications. We present two security schemes that are suitable for both fixed reader and mobile/wireless reader environments, the mutual authentication and the collaborative authentication schemes respectively. Both schemes are suited to the computational constraints of EPC Class-1 Gen-2 passive RFID tags as only the cyclic redundancy check (CRC) and pseudo random number generator (PRNG) functions that passive RFID tags are capable of are used. Detailed security analysis of both our schemes show that they offer robust security properties in terms of tag anonymity, tag untraceability and reader privacy while at the same time being robust to replay, tag impersonation and desynchronisation attacks. Simulations results are also presented to study the scalability of the schemes and its impact on authentication delay. In addition, Yeh et al. (2010) [20] proposed a security scheme for EPC Class-1 Gen-2 based mobile/wireless RFID systems. We show that this scheme has a security vulnerability and is not suitable for mobile/wireless RFID systems.     

Anti-cloning protocol suitable to EPCglobal Class-1 Generation-2 RFID systems

Radio frequency Identification (RFID) systems are used to identify remote objects equipped with RFID tags by wireless scanning without manual intervention. Recently, EPCglobal proposed the Electronic Product Code (EPC) that is a coding scheme considered to be a possible successor to bar-code with added functionalities. In RFID-based applications where RFID tags are used to identify and track tagged objects, an RFID tag emits its EPC in plaintext. This makes the tag inevitably vulnerable to cloning attacks as well as information leakage and password disclosure. In this paper, we propose a novel anti-cloning method in accordance with the EPCglobal Class-1 Generation-2 (C1G2) standard. Our method only uses functions that can be supported by the standard and abides by the communication flow of the standard. The method is also secure against threats such as information leakage and password disclosure.     

EPC Gen2标准下强安全射频识别认证协议

由于现在很多射频识别（RFID）认证协议不符合EPC Class 1 Gen 2(EPC Gen2)标准的要求,同时对RFID系统的计算能力要求很高,因此很难在低端标签中实现。针对上述问题,通过分析已有协议的安全性,总结出不安全协议的缺陷,提出了一种新的基于EPC Gen2 标准的RFID认证协议,并采用BAN逻辑对协议进行了安全性证明。通过安全性分析,新协议满足了信息机密性、数据完整性和身份真实性的RFID系统认证协议的安全需求。

Conformation of EPC Class 1 Generation 2 standards RFID system with mutual authentication and privacy protection

Radio frequency identification (RFID) technology has recently aroused great interest due to its convenience and economic efficiency. Through RFID become popular worldwide, it is susceptible to various attacks and security problems. Since RFID systems use wireless transmission, user privacy may be compromised by malicious people intercepting the information contained in the RFID tags. Many of the methods previously proposed to prevent such attacks do not adequately protect privacy or reduce database loading. In this paper, we propose a new authentication and encryption method that conforms to the EPC Class 1 Generation 2 standards to ensure RFID security between tags and readers. Our scheme not only reduces database loading, but also ensures user privacy. Finally, we survey our scheme from several security viewpoints, and prove its feasibility for use in several applications.     

面向EPC Gen2标准的RFID标签分组多位隙并行识别协议

在分析EPCglobal UHF class1 generation2和基于DFSA协议的高速标签识别算法的基础上,采用位隙FSA协议标签响应标志位隙的设置方法,通过在标签上设置一个组位隙响应标志字,提出了一种EPC Gen2 标准下的RFID标签分组多位隙并行识别协议GMBPIP,设计了一条新的分组查询命令和基于DFSA的多组标签并行识别协议流程,从理论上了分析GMBPIP协议的性能,并使用EPC Gen2 标准协议时间参数进行了仿真实验。结果表明,GMBPIP协议在不增加标签太多计算负担的情况下,能够在EPC Gen2标准下有效降低时隙空闲率和冲突率,提高了标签的识别率、时隙利用率;平均识别率不仅突破了帧时隙ALOHA协议最高36.8%的瓶颈,而且高于目前文献所述同类算法的性能指标,达到了70.95%~81.61%。GMBPIP可以作为低成本RFID系统高速识别大量被动标签的支撑协议。     

ID-Services: an RFID middleware architecture for mobile applications

The use of RFID middleware to support application development for and integration of RFID hardware into information systems has become quite common in RFID applications where reader devices remain stationary, which currently represents the largest part of all RFID applications in use. Another field for applying RFID technology which is offering a huge set of novel possibilities and applications are mobile applications, where readers are no longer fixed. In order to address the specific issues of mobile RFID-enabled applications and to support developers in rapid application development, we present ID-Services, an architecture for an RFID middleware that is designed to support mobile applications. The ID-Services approach has been used to implement MoVIS (Mobile Visitor Information System), a mobile application which allows museum visitors to request individually adapted multimedia information about exhibits in an intuitive way.     

Vulnerability of an RFID authentication protocol conforming to EPC Class 1 Generation 2 Standards

Recently, Chien et al. proposed an RFID authentication protocol, which consists of only the cyclic redundancy code (CRC) and the pseudo-random number generator (PRNG) [H. Chien, C. Chen, Mutual Authentication Protocol for RFID Conforming to EPC Class 1 Generation 2 Standards, Computer Standards & Interfaces, vol. 29, Elsevier, 2007, pp. 254–259]. They claimed that the protocol conforms to current EPC tags, and would be secure against all attacks on RFID systems. However, in this paper, we show that the protocol is not secure; firstly an attacker can impersonate a valid tag temporarily by a single eavesdropping. Secondly the attacker can forge a tag permanently by eavesdropping two consecutive sessions. Finally he can make a valid tag useless (DoS attack) by modifying the second attack slightly. The computational complexities of the attacks are so practicable that Chien et al.'s protocol cannot enhance the RFID security any more than the original EPC standard.
